Re: [QGIS-Developer] QGIS Desktop as WMS client - purpose of format "Feature"
Hi, Forget to add other explanations: The retrieve geometry from wms is useful also because is in any available srs. So the user can have one single geometry in an srs reprojected on server rather than on qgis. This is better because the wms server can reproject using proprietary grids . Meanwhile the reprojection on qgis is without proprietary grid and so less exact.

Re: [QGIS-Developer] QGIS Desktop as WMS client - purpose of format "Feature"
Hi, We use the feature option in getfeatureinfo in qgis to allow the users to retrieve the geometry from a feature on the map. This really useful rather than wfs because wfs is inefficient and we often dont want allow the downloading of the featureset. So we disable the wfs and suggest to the users to retrieve one single geometry using the feature option in getfeatureinfo in qgis wns client. Regards, A.

Re: [Qgis-developer] Missing the support for scale parameter in WMS Legend
Hi Nyal, Unfortunatelly no. No news on this. I have no the skill to understand what is the code interested. I know it should on one the the committed link due a report send us at that time. Now I try to install the qgis 2.2 or qgis 2.4, and try to test it again. Maybe I could do a video. >(* insert the usual disclaimer about "no one should ever sponsor a > feature without an explicit requirement for unit tests in the > contract") But for some enhancement like this, "the wms parameter scale" s quite difficult to do a unit test. Please pay attention that the enhancement funded from us was only in the provider wms (the client). The qgis-server almost at that time don't support this feature (the abiity to have distinct scale rendering for the same layer). This was a feature enhancement forward the other wms-server like geoserver or mapserver. So I guess will be quite difficult to do a UNIT-TEST. Even if we want to do a unit-test, it need a wms service always available and under the control of the qgis team, and obviously it should be a qgis-server. So there was not more chance to be able to test this enhancement that is specifically for the wms client interface. When is developed an enhancement for a WMS in a GIS client the test should be done on more than the own wms service (qgis-server). So need a mapserver, a geoserver and a qgis-server always availables. I know this is quite impossible so also is quite impossible to do a well formed unit-test in the wms section.

Hi Nathan I find only this commit. https://github.com/qgis/QGIS/commit/836e1a86368f9eace236d24ba40b7af77a6bc63d But it speak of don't refresh legend symbology everytime the extent changes I'm not so skill on qgis code to understand what it do.

Effectivelly my tests on the qgis 2.18 on an our wms ehre the legend is sensible to the scale confirm that it is not working, but I still don't know why it was removed.

Re: [Qgis-developer] Valid or invalid geom in PostGIS?
You have right. The ST_MAkeVaild is capable to return a valid geometry. But it dont remove redundant vertexs. The redundant vertex is not always considered an Unvalidity (I guess yes) so originally it was separated from the MakeValid function. I guess is better if qgis do: before a removeredundants and after a makevalid. Also pay attention to extract right type from the makevalid with the couple forcecollection and after the extractcollection (or collectionextract).

Re: [Qgis-developer] Labelling in QGIS Server/Lizmap
Hi, our webgis framework "Tolomeo" multilayer and multiwms is working like this. It group all the layers in one only service GetMap request for every service. But when the tree is filled with layer coming from different wms services. It must split also for service and for layer. So is quite impossible to have 1 only request , but often there are 3-4 request everyone with more than one layer instead of 20-30 requests. Another question is if the user move the order of the layer up or down in the tree. The framework should recognize this and change the splitting of the request to support the new order. Another question is if the user request some client operation like put a transparency on a layer. This mean that that laywe should request separatly from the other to allow after the change of transparency on the client side. This to explain that the question can rapidly increase in complexity.

Re: [Qgis-developer] [Server] performance questions
I Guess the time difference between the qgis desktop and qgis-server when using a postgres, is due to the protocol. Infact the http is a connection-less session-less protocoll, so after every map the qgis-server disconnect from postgres. Instead when you work on a qgis desktop as a user on its own pc you are connectin with a postgres and sray connected for all the time. So the postgres don't waste time to open and staryup your connection. Also don't forget that if you stay about 18-20 minutes without do nothing on qgis in a postgres connection. The postgres kill your connection and your qgis go in crazy state.

Re: [Qgis-developer] Contextual WMS legend graphics forgets option
Hi, strk, and Paolo. I can confirm our goal was to have a per-layer option. Because not all the layers in a wms service are good to have a contextual legend. Actually the more layer don't need a contextual legend. Only few layer with really many layer are this need. Of course the proebl of a per-layer configuration is to have a web client capable to do a non standard call. Meanwhile a per-server configuration will work with every client. This is why we fund also the capability of qgis to set the wms provider to do a contextual-client call. With a per-server configuration this will not need. But another question about why we prefer a per-client configuration is that this is the same configuration used by mapserver in it contextual legend. nfact we originally use the contextual legend in mapserver and after see how good it was on some layer we decided to fund to have the same contextual legend call in qgis-server. This is a good question fo interoperability to have the same request in more then one wms server. This kind of request is surely not standard for ogc but is the same for mapserver and for qgis-server. This mean that a wms provider client that can call the contextual legend on mapserver can call also on qgis-server. Instead If qgis-server was working with a different kind of request for contextual legend, it will be incompatibile and this mean that every client that support the mapserver contextual call don't conseguentially support the qgis-server contextual call. The theird question is that a per-client configuration will allow t have the full legend and also the contextual legend. Instead aper-server configuration will allow to have always only one of both legends. This mean a lesser useful usage. Because not always is useful to have the contextual legend (also on a lyar with many domains).

The default is for contextual WMS legend to be off (it's not a standard call). Eventually you might want a per-server default configuration, but would be an enhancement. sorry, I do not see your point: if an user chooses to display the legend for a server, it is more than likely that he will expect further connections to that server will remember his choice. but OK, it can be an enhancement. I would even argue that such option should not exist. Most users will probably not understand its meaning. If necessary, such option should be in WMS server configuration dialog, not in the main WMS dialog. Anyway I think QGIS should try to figure it out itself whether the server supports contextual legend. Contextual legend is a non-standard feature, not sure how QGIS could rely on capability info to figure out. Moreover the user might want it enabled only for some of the layers. The per-layer option was explicitly requested by the funding party (Regione Toscana). So I would see a per-server option to determine a per-layer default (overridable) and eventually an autodetect choice for that option in case there's a likely-to-work way to do that. --strk; ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer -- - Andrea Peri . . . . . . . . . qwerty àèìòù - ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Snapping tolerance
Hi, perhaps I dont understand well what this mean. Infact we usually editing always in native reference system, never editing in reprojected SRS. But I guess that using the project reference system instead of the layer srs for snap operations could cause the snap will affect from an error due to the reprojection operation. If this is true, this could mean that the editing result could change moving from a PC where the precision in due to some local NTv2 data (more precision in reporjection), to another pc where the NTv2 are not available. And also it could depend from the trasformation choose for the reprojection. Im worng the mean of the snap question ?

Recently there was even a bug report filed for that: https://hub.qgis.org/issues/11634 I would like to change the behavior so that the map units in snapping config dialog would mean units in project's CRS. Would there be any objections? Alternatively we could just rename map units to layer units to make it less surprising (and eventually add a third option to use project's units).

This concerns mainly the print composer legend, but perhaps the legend in the legend tree could be solved at the same time. At the same time we should also think how these improved legends could be exposed in QGIS server. I am trying to list the things I would like to see improved: 1. Support for legends for graphical properties defined with map units. Currently these legends display in the print composer at very strange, unpredictable and unusable sizes. E.g. a stroke-width or dash defined in map units is either way too big or too small. Same for symbol sizes defined in map units. We need a way to translate these map units in usable paper units suitable for display in the legend. Let the map author define a corresponding mm size (along with the map units) - solely for the display of the legend. 2. Display of legends for graphical properties defined with data-defined symbology. We need a way to specify common graphical properties in the legend that are of interest in the legend. F.e. - if I define the colors data-defined I would like to be able to specify the expected colors that may appear in my data/project. This could be either done dynamically (by scanning the data) or statically (decided by the map author). Perhaps both methods. To me, the static method may be more predictable and more performant. 3. Legends for diagrams (pie charts, bar charts) - something similar to http://esri.force.com/servlet/rtaImage?eid=08730008Nki; feoid=Bodyrefid=0EM3000Co0O - showing both sizes and colors - nicely stacked into each other. 4.

But the European require to certificate the reality of the Fund putting a disclaimer on the product realized. Otherwise no fund at all. I guess a citation in a page that is mied with many other developers is not what ask the europe , because is not possible to localize exactly what was don with the european fund. Ths is surely a problem and I guess is really hard to use successfully European fund for enhancement on QGIS. Instead the EU fund are really good for start new never existent before gfoss products.

Re: [Qgis-developer] Memory Layers - some proposals
I agree. It seem me a silly question. If an user choose a memory layer it know that is a memory layer :) So it is not a permanent dataset. I like the memory layer because they as really useful for temporary elaborations and quickly tests. lso another question is. If an user choose the memory layer it crunch the ram resources. And after it begin to ask for more resources because its million records daataset is not well used with the memory layer. However if like to put a memory layer persistent. Why dont return to old question. Change the project save from XML to a spatialite ? Storing the project in a spatialite will allow easily to host also in the spatialte the datasets if this is the like of the qgis community. Also the spatialite start to support also the raster with rasterlite extension. So tomorrow you should do also a memory raster layer. Regards, Andrea. 2014-09-25 9:19 GMT+02:00 Matthias Kuhn matthias.k...@gmx.ch: Hi, Please excuse my ignorance, but Why would you want a memory (as in RAM) layer when you want permanent data? For portability reasons? That's fine, but then we should offer a possibility to support portability support for a real geo-format (with spatial index and all the goodies). To stuff it into the project file there can be support from a plugin, but I would not vote for adding this to core. To me it seems that the current demand for this comes mainly from wrong expectations created by the name (and people subsequently loosing data). And we can fix the name. For the portability issue, I'd rather go the longer way but get it right.

Re: [Qgis-developer] Module dependencies
Hi Paolo, I have some doubt on automatic installation of dependencies. This fear this will be a bad practice for security. As example: one black-hacker could create a simply and apparently innocent plugin for qgis. A plugin that the responsible manager of the plugin repo of qgis could surely admit in the repo of qgis. Because it seem to have no particular problems except some extern dependencies. But that plugin will have a dependencies that cause the installer automatically to install another plugin from external source. And this thirdy part plugin could be a malware.

Re: [Qgis-developer] QEP: QGIS Mapserver Python Plugins
I guess the main goal is to avoid that the adopt of python on server could slow it. Infact , the main difference from a desktop and a server is that the first is serving only one perosn and this mean that the user could wait also for a work for himself. Instead a server is used from many users and every of them dont like to wait too much. So the preferrable is if the python server solution sill be optional. So who don't need it could to not compile it. Sincerelly I don t see any advantage in the python server side inside the qgis. The only scenario I could admit is for a rapid prototype of some solution, but afer, this for an usage in a production environment the python solution should be transform in a C/C++ solution to have the sufficient execution rapidity.

August 2014, 14.49:47 schrieb Alessandro Pasotti: as anticipated to some of you during the last HF, I've started to add Python plugins support for the server side. The rationale behind server plugins is doublefold: first they could provide additional services without the need to touch the C++ codebase, second they allow for GUI-based configuration since the server plugins are not separated from the desktop plugins (of course the environment and permissions should be carefully configured to allow information sharing from the desktop user to the webserver user ). This looks like the first real case for an RFC! I'm quite sceptical adding Python to QGIS server. In my opinion this should be discussed thoroughly first. Hello Pirmin, thanks for the feedback!!! At least this is the start of a discussion :) I knew from previous conversations with some of you that adding python plugins to the server was not at the top of the priority list and I added QEP (RFC) in the original subject because I know this topic must be discussed: I'm not going to do a PR anytime soon, and my implementation is more like an hack to see how far can I go with this idea, but, so far, it seems quite promising. Everybody knows how has been important to have Python plugins on the desktop side, coding in Python is 5 to 10 times faster than building C++ code and moreover the lower barrier to start being productive will bring a lot of new functionalities from a larger pool of developers. Last but not least, python plugins do not need to pass the PR/pull/build/relase cycle that affect the C++ core, which adds a considerable delay to bug fixes and new features. That said, I would really like to hear more from you all about the reasons to be against this idea. -- Alessandro Pasotti w3: www.itopen.it ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer -- - Andrea Peri . . . . . . . . . qwerty àèìòù - ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

If you give them voting rights, and potentially veto right (not sure how the rules of the voting system of QGIS are), then they are defacto PSC members, since they can steer the direction of the project. Not saying this is bad. Just a consequence. I'd say neither psc nor commit rights are a good fit. While I agree that the psc should definitely have a say, not everyone on the psc is a developer or has c++ coding experience. Similarly, we have people who have commit rights who are neither developers nor psc members. I had the same impression as Nyall. PSC is meant to steer direction of the whole project, not to deal with technical details of implementations in QEPs - after all, only 3 out of 7 positions are meant for developers. At the same time I understand that creating another developer committee would make things more complex. I think that voting on QEPs could be started when the QEP's author has impression that enough consensus was reached. Most projects also allow their RFCs to go to 'deferred' state if the proposal is too controversial. Since a big part of the qep would be commenting on proposed technical architecture, I think its fairly important that developers have a good say in the process. But conversely if the qep process determines the direction of QGIS, then non devs on the psc should also have a say. Originally I thought that only new functionality would be covered by QEPs, but it is actually quite useful to have one common process for any significant changes in the project - ranging from development stuff through infrastructure changes to organizational changes (like introduction of trademark). So it makes sense to have PSC vote on QEPs. So my 2c: - From the PSC point of view the intention is that the PSC facilitate teams to work on specific areas e.g. documentation team, UX team etc. I think RFC's would probably come under Marco's remit (PSC: Code Manager). I don't think it is necessary for the whole PSC to be involved unless Marco wants help. So the normal modus operandi would be: * Marco forms an RFC review team * People submit RFC's * Review team accepts or denies the RFC's * PSC is available to resolve any disputes that may arise or aid in decision making where review team feels the impact on the project is broad.

Re: [Qgis-developer] Geospackage Slow in QGIS
Hi Stefan, More information to explain better: The code is available in qgis. But don't work. I try it using a spatialite 4.2.0 created with spatialite-gui. And having a table with two geometry fields. One of type Polygon and another of type Point (the centroids of the polygons geometries). Using the OGR provider it see both the geometry, but when load them the point layer don't work.

[Qgis-developer] QGIS_server: add a maptip field at the getfeatureinfo response.
Hi,
I notice on some response text/html to a GetFeatureInfo,
on some layer qgis-server add an hardcoded field named maptip.
Also I notice it is not always added but nly on some layer.
I found the code in the
qgswmsserver.cpp
//add maptip attribute based on html/expression (in case there
is no maptip attribute)
if ( layer-fieldNameIndex( layer-displayField() ) 0 )
{
QString displayField = layer-displayField();
if ( !displayField.isEmpty() )
{
QDomElement maptipElem = infoDocument.createElement( Attribute );
maptipElem.setAttribute( name, maptip );
maptipElem.setAttribute( value,
QgsExpression::replaceExpressionText( displayField, feature, layer )
);
featureElement.appendChild( maptipElem );
}
}
Why this adding hardcoded ?
I guess it could be a refuse of something other old code ? And so removable ?
Actually this is quite fastidiosus (embarassing) for us, because it is
a not corresponding fied to the real structure of the layer.
Thx,

The only necessary change is to substitute a /BR with a HR class=.. tag. But using the same css is possible to hide the line of the hr tag and aso change its height.

[Qgis-developer] How do a correct GetFeatureInfo request
Hi, I send this message originally to user list, but perhaps is better to send to this list. And meanwhile I update with the last news. We are having some troubles with qgis-server when send a GetFeatureInfo from our framework webgis (Tolomeo webgis framework). QGIS-Server is returning a Service not specified. The SERVICE parameter is mandatory error. After some test, we perhaps find the issue: So understand better so I need to hve an information on qgis-server. When do a POST GetFeatureInfo request, the parameter SERVICE should be set on the querystring or in a post parameter ? ;) Infact seem the issue is that the SERVICE parameter is effectively present but perhaps is not where qgis-server would have it . Our framework is usually working with mapserver and geoserver and its settings for parameter GetFeatureInfo work surely with them both. Now we try to understand where the SERVICE paramete is wanted by qgis-server when the client do a post request. Any hint is welcome. Thx, - After this message , we have do some other test. The results are that effectively seem the QGIS-Server need to have all the aprameters in POST section and seem to ignore every paameter put in the querystring. Our framewor is using the post only to pass the huges coordinates of a polyon when the user start to edit it. Instead usually send the usually parameters in the querystring section. However after this experience with qgis-server, because this is effectively a no more clear section of HTTP specs. We start to change the work of out framework to repeat the same parameter in the query string also in the POST parameters.

Re: [Qgis-developer] QgisLogger can be a serious bottleneck
Hi GioHappy, the empty-collection is absolutelly not necessarylly a bug. It is the obviously result of an operation on a machine (like the computer) with a binary finite arithmetic. Usually the empty is due to a too low value to be describe with a finite binary arithmetic. If the dataset is small or it is topologically correct (this not mean only to be snapped). the collection results never happened. Instead if the dataset is not topologically correct and is big the probability to have some collection result grow. We tipically have alway an 0.01% of collection on our results. I suggest you to use directly postgis or spatialite to do this kind of operations. In these products you have the useful tools to resolve the collections correctly.

Re: [Qgis-developer] QgisLogger can be a serious bottleneck
Thx GioHappy, this is imprtant for me to know. So is surely better to use the postgis or spatialite because it allow you to extract from the collection the section with the right type. If you do a difference beetwen two polygons is the result is a collection with a polygon section and a point section. You should extract the polygon and discard the point. If the strategu is discard all the collection this mean that on qgis the difference could lost domething of important and so potentially the difference do a wrong result.

Re: [Qgis-developer] Geom collection and QGIS (was QgisLogger can be a serious bottleneck)
Is wrong. The geos return a collection when the collectionis the right result. if the result is a collection like: collection (multipolygons, multilinestrings, multipoint) why it should remove the lines and points. It could be useful to the client. The fact that the client is capable to understand only point/line and polgons is a problem of the client , not of the geos. If the invoker is not capable to understand collection, but it want do operation that could return collection.

Re: [Qgis-developer] qgis-server will crash on a specific project
Hi, I confirm. There is a layer limit in QGIS-Server I do a huge test removing one by one all the layers from my project. And after the removing of every single layer I retest the working. Aftr a while of time. I reach the limit. And the project begin to run. I do other test to exclude that was the number of layer inside a single group. All the test give the response that seem to be the max number of layers in a project. So the question is: QGIS desktop allow to put more layers rather than how many are accepted from qgis-server. This not good for a WYSIWYG system. Ok, I will try to patch my server when found exactly where is the problem. Meanwhile, Now the question is on what structure is this limit ? I don't guess it is simply a layer limit but perhaps a more specific structure. Now I have a project that crash , and a project with a one less layer that work. Doing a DIFF beetween the two projects I see the possible structure breakable are: layer-tree-canvas - custom-order - item maplayer Digitizing - LayerSnappingList - value (type QStringList) Digitizing - LayerSnappingEnabledList - value (type QStringList) Digitizing - LayerSnapToList - value (type QStringList) Digitizing - LayerSnappingToleranceList - value (type QStringList) I check if in the code there is a limited array dimension for this objects.

Re: [Qgis-developer] qgis-server will crash on a specific project
Hi, thx for response. meanwhile, I notice that the max allowed layers is exactly 101. This mean (knowing C/C++) an array of 100 elements.

Re: [Qgis-developer] qgis-server will crash on a specific project
I guess it is not a timeout question. To avoid the interference of the server web I test it running into a shell (a cgi is always an executables) I guess there is something else. If I set the MAX_CACHE_LAYERS qgis server run and return the getcapabilities (I ask it to test) otherwise it crash. My project seem to have 164 layers. But perhaps I count wrong, because if I set MAX_CACHE_LAYERS = 163 it run. Instead if I set =162 it crash. :) 2014-06-22 16:01 GMT+02:00 Marco Hugentobler marco.hugentob...@sourcepole.ch: Just tried it with a project containing 111 layers here and the WMS server works fine for me.

In the SLD world this was allowed and a unfortunately and worst understanding of it will born a lot of incompatible dialects. Also in the metadata world (iso19115) the possibility to extend the specs will produce incompatibility monster. :) This exists in the html world, over time there are winners. If you don't care to use the extra features you are always welcome to use the base which is 100% compliant. The winners or some compromise variant end up in the next version of the spec. I guess surely better and easy is put the new functions in in a distinct and new kind of request. After reading the WMS doc I believe using the tags I mention is the correct way to do it. Technically the result is WMS 1.3.0 compliant. Clients are free to ignore the extra functions as not using them does not remove any required features. As to why fund it?

Looking at an analogy with html specs I find this limitation appalling short-sighted. It means there can be no innovation testing new features with the spec unless you manage to get it into the future spec. I find it hard to comprehend that clients don't just skip tags that fail to match a known tag. In html land its very common for some browsers to know some non-standard tags, which are new features in testing to be proposed or reworked into future standards. IE's policy of only adhering to the spec and including no experimental tag support has been seen be web designers as discouraging to any change. Why, because their is no way to publicly test new ideas. So from the QGIS side, in order to comply we would need to reply with only allowed tags if a user requests WMS=1.3.0, we can reply with more stuff like GetPrint if they don't specify that version. Or perhaps we have to invent a 1.3.0+ variant specifically for when a user knows it's QGIS server. Anyone more familiar with WMS that can shed more light on the best way to work around this issue and have both compliance and the ability to add extra features that have no standard equivalent yet. My point still stands, that EU agencies with this concern should be funding compliance efforts, not removing funding for lack of compliance.

Re: [Qgis-developer] [Qgis-user] A discussion: is qgis still affordable in Europe if it violate the Inspire directive ?
Hi, The last response of Jef in the ticket explain clearly what it the strateguy of qgis.The important is tobe compatible with other software GS. Thie mean the QGIS-server don't metter for real wms compatibility and interoperability. I guess is not really clear that the XML response to GetCapabilities is a protocol tocommunication between system. It is not only for other gis softwar. It is for every system can need to ask to the server wms. The response need to be aboslutely compatible tobe really interoperable. As example: this simplest case: http://www502.regione.toscana.it/geoscopio/servizi/wms/OFC.htm Tis html page is product autocatically from an our system Not gis that call the mapserver and with an xslt that parse the XML response produce this html page periodically. also thi http://www502.regione.toscana.it/geoscopio/servizi/wms/INFRASTRUTTURE_E_PRESIDI.htm and this http://www502.regione.toscana.it/geoscopio/servizi/wms/CTR.htm and so on Also we could use the same mechanism to implement a B2B colloquial betwen a metadato system and other systems or to the wms server. This mean to be interoprability. Mean grant to work with every other system that work with the same specs (WMS spacs in this case), not only with other GIS software. The server wms is not only a maps-dispenser. This page http://www502.regione.toscana.it/geoscopio/servizi/wfs/html/comuni.html is product from another xslt proc that again parse a WFS response from a TinyOWS system (please notice also the wfs of qgis-server is not complaint to specs) This is an automatically parse of a wfs request to a tinyows that return the list of cadastral parcels and propose this page. http://www502.regione.toscana.it/geoscopio/servizi/wfs/html/elenco_foglicat.html?com=047001 This is the list of street of a single comunity http://www502.regione.toscana.it/geoscopio/servizi/wfs/html/elenco_strade.html?com=047001 And clicking on one of them you can jump to the system webgis to see them.

It mean to use many system differents but all understanding the same single set of informations and capable to exchange to each other the same information. Is not only a question betwen three or four software GIS. When I say arcgis or autoca try to explain that could be more other system that could be n difficult to operate with a qgis-server that resonse a non standard XML response at getcapability request. But if the response of qgis group is we see the main GIS software work and this is sufficient for us. This mean the QGIS-Server is not planning to be WMS compliant. I test the response with XMLSpy and see it is not compliant WMS because it fail when use the official xsd from OGC. Instead other product (mapserver and geoserver) will pass the test. If I report this issue and the response is: is all okay for us. This response is more clearly of every other. Bye. Andrea. Il 08/giu/2014 09:07 Mats Elfström mats.elfst...@gmail.com ha scritto: Hi!

Re: [Qgis-developer] Qgis server is really compliant OGC?
Hi, I update the ticket. The first problem is that the tag GetLegendGraphics is without a namespace. This is pretty easy to resolve. Unfortunately after resolve this there is two more complex problems. The GetStyle and GetPrint tags. The first is a dismissed tag from OGC available in WMS 1.1.0 and not available in WMS 1.3.0. Unfortunately the qgis declare its capabilities to be Version=1.3.0. The second tag GetPrint seem to be a total invention f GetPrint. AFAI it don't be include in a GetCapabilities response that is uniquely dedicate to list standard elements. If QGIS need to report this information it should be add another kind of response something like: GetQGISCapabilities and put inside it all the tags it need and are not available in the standard WMS.

Re: [Qgis-developer] [Qgis-user] A discussion: is qgis still affordable in Europe if it violate the Inspire directive ?
No, you can esperiment new functionality . Simply you cannot put them in a standard response. The right solution is what say Steafn in ticket. QGIS has a request QGISPropterySettings. The new powerful but incompatible features put them in it. Don't abuse of standard responses. . Also: You don't undestand. I don't spaek the agency EU. The inspire directive say: that the europan menbers italy, france, deutch, and so on... must recepit the directive them and all their sub agency national and local. The directive don't say fund to put a qgis to be compiant. The drective say use only compliant and interoperability wms product . The EU put no money for this. Every menber can use it want . Commercial or Open product is indifferent. The imprtant is that it is interoperability. The Geoserver is interoperabilyt The Mapserver is interoperability. Why A public administration should choose QGIS-server ? It mean lost fund when there is some one more and more copliant with Inspire. What is the motivation to spend public resource to have a a QGIS-server comliant. I guess this should be interest of who sell service on QGIS to have a qgis compliant otherwise it has not a market in the public administrations. Or better again. Why there is a GetPrint and GetStyle s tags ? In the response: the more easy solution is remove these two tags. I do it in few minutes and can give the patch at we ask me. So why there is this two tags ? They are put from someone. This someone has break the qgis wms compatibility. SO AFAIK should be it to fund for repair what it break.

Re: [Qgis-developer] [Qgis-user] A discussion: is qgis still affordable in Europe if it violate the Inspire directive ?
This is not only a inspire need. This more important because is an WMS invalidity. I try to explain better. The mapserver was not inpire compliant because it miss of something metadata elements. OK, but almost it was OGC WMS compliant. The inspire specs say take an OGC WMS compliant and on it add something that I say to you. The QGIS IS not WMS Compliant . This is worst than inspire non compliant. Also inspire say the interoperability is the base to start all together. The invalidity of qgis-server is due to the add of a proprietary tag that fail the xsd tests OGC WMS. So it is not interoperability with other products. This is worst than : To be more inspire compliant. The question here is: qgis-erver is not OGC WMS compliant. However I say what is the problem: The ticket is here: http://hub.qgis.org/issues/10489 The problem are a worst definition of the Tag GetLegendGraphics, but as report in the ticket the solution is described in the ticket. The other two probles are the presence of a GetStyle in the wms 1.3.0 response. The GetStyle was dismissed from OGC in the 1.3.0 response. And the presence of the proprietary tag GetPrint. My simplesolution was change the GetLegendGraphics. This is a simply change in the code. I have patched my server using sld prefix because is the standard. But also the solution of Jef to use the qgis prefix is ok because is valid for a good validator (xmlspy I use). So If the qgis groups decide to adopt the qgis prefix namespace for GetLegendGraphics, I have no problem to change my patch. Otherwise I leave the standard name sld. The other two problems. GetStyles and GetPrint. They are not tags of the WMS 1.3.0 specs. So they should not be present in the response. The solution is remove them or put them in the specific dedicated section. But obviously they are put correctly in that section.

I guess surely better and easy is put the new functions in in a distinct and new kind of request. After reading the WMS doc I believe using the tags I mention is the correct way to do it. Technically the result is WMS 1.3.0 compliant. Clients are free to ignore the extra functions as not using them does not remove any required features. As to why fund it? If QGIS provides other value to your organization in some other way, total cost of operation may be lower to simply ensure it's compliant rather than to switch software or have to use multiple software.

Re: [Qgis-developer] Geospackage Slow in QGIS
Hi Giovanni. You have point an interesting question. The question is: geopackage and spatialite will be binary compatible (almost in the blob where there are store the geometry) ? I guess no because I don't realize how a geopackage spec could support some different binary formats. If this is true (i cannot be sure now, hope wrong obviously) this mean that will be another different format in a sqlite. The first is spatialite, the second is the porting of qgis to spatialite, the third is this next coming version of geopackage on spatialite. A. 2014-05-17 14:45 GMT+02:00 G. Allegri gioha...@gmail.com: The spatialite will never to be a real interchange format if the only software to use it is qgis and the same qgis is not real compatible with the original spatialite spec. So the spatialite actually is a really good and strong work format . Instead surely geopackage are no one strong point in elaboration so I'm not surprise that it is slow. As you will know the GeoPackage SQLite Extension is pending for future versions of the specification. In case it would make Spatialite/Geopackage purposesquite similar... giovanni Il 17/05/2014 11:24, Paolo Cavallini ha scritto: Il 17/05/2014 11:03, Andrea Peri ha scritto: Do you know the requirements of gpkg ?

Re: [Qgis-developer] Spatial index - what about having it automatically created and updated ?
I guess more better is to use this extremely simple batch and create all the index in one step only. sing the gdal/ogr from osgeo4w. http://trac.osgeo.org/gdal/wiki/BatchCreationIndexesForShapefilesOnDOS Regards, 2014-02-27 10:47 GMT+01:00 kimaidou kimai...@gmail.com: Hi list, I have some concerns about spatial indexes in QGIS. Spatial indexes are very usefull, and for me rather mandatory as soon as you deal with more than 100 features. I would like to share some ideas about them : 1) Extend QGIS so that it can create spatial indexes for more vector format. If I am correct, for now only Shapefiles and Database vector layers can have a spatial index created by QGIS . Why not for GeoJson, CSV files, etc ? 2) If possible, create a spatial index for each vector layer added to the canvas if no one is already present. Since it is a quite fast operation, the small time needed is worth it. 3) If possible, update the spatial index (replace the old qix by a new one) every time the vector layer is updated. No need to do so for database layers, but this can be very usefull for big shapefiles. I have seen some people creating a spatial index, then as time passes, they add more and more data into the shapefile but forget to update the spatial index. Sometimes this can lead to some data not displayed in QGIS because QGIs seems to rely on the outdatedSpatial index. For me, using spatial indexes is like brushing my teeth : I do it very often without even thinking of it. But many users do not know that spatial indexes exists, or do it but forget to use them as needed. I really think QGIS should help them to improve perfs in the background.

Re: [Qgis-developer] Spatial index - what about having it automatically created and updated ?
Create or updte a spatial index in a table is a danger operation .. So in postgis it is availabale only to user with write grant. QGIS is unable to understand if a connection is readonly or write enable so try to do an automatic update is a trouble-matic operation if a table was open from a read-only user. Another question is why it should be complex for an user to create an index ? A second question is what kind of index ? On postgis is possible to do more than one index. A table could have more than one geometry and every one could have a spatial index or not. But an index is a space consuming and often the index is needed on 1 only geometry field menawhile the other geometry field are only for special uses. To do always automatically a spatial index on every geometry filed is really a not useful operation in these use-case.

I think it's a great idea to do this automatically with large ogr data sources as you said you should probably ask the gdal-dev list about which drivers support spatial index creation an automatic update. cheers Etienne On Thu, Feb 27, 2014 at 7:51 AM, kimaidou kimai...@gmail.com wrote: Hi 2014-02-27 11:14 GMT+01:00 Andrea Peri aperi2...@gmail.com: I guess more better is to use this extremely simple batch and create all the index in one step only. sing the gdal/ogr from osgeo4w. http://trac.osgeo.org/gdal/wiki/BatchCreationIndexesForShapefilesOnDOS Regards, As I said, I am thinking of non power users.

Hi,
I have to confirm that the file size is huge and saving performance is
slow.
I'd like to emphasize that this is a show stopper for me for/against
Spatialite to become the Shapefile of the future!
I did not yet look into the QGIS driver code, but I assume (and hope)
that at least the saving performance can be enhanced.

2014/1/24 Rafael Krucker rkruc...@hsr.ch:
Hello all
I've noticed recently (QGIS 2.0.1, Windows 7 64 bit), that, when I'm
processing a shapefile as layer, even very small ones, the operation
'save
as spatialite' takes forever. With a small shapefile (1 KB), the
process of
converting takes up to 3 minutes, the generated spatiallite is then
always
around 4000 bigger (4.21 MB). These ratios are the same, no matter how
big
the file is, the time taken enlarges linearly it seems.
When the export is a shapefile again, the whole thing is a matter of
seconds.
Is this due to some kind of buffering issues or does this conversetion
simply take that many resources?
Kind regards and thanks in advance for any pointers
Rafael
