Re: [Qgis-user] WMS with filter function

[Andrea Peri]

Hi, I guess an important reason because is not easy the develope what you
need is that the filter section is not  standardized in the wms 1.3.0 specs.

Re: [Qgis-user] MS SQL Server connection on Linux

When try to connect from php to a sql server 2015 std edt on a debian  10

Re: [Qgis-user] Loss of data

[Andrea Peri]

Restoring only the dbf will do am error for a shapefile because it is sync
with shp and shx.
The retrieve should fo for all three files or nothing.
The dhx could be recalculate from dbf and shp. But dbf and shp must be
sync-ed.

Re: [Qgis-user] AEROFOTOGRAMMETRICO

[Andrea Peri]

Ciao,
cosa intendi per Base Aerofotogrmmetrica?

La restituzione aerofotogrammetrica viene eseguita su fotogrammi dei voli
aerei,
dalla restituzione aerofotogramemtrica viene prodotto la CTR che usualmente
e' in DWG (o DXF).

Per cui forse intendi che stai cercando la CTR in formato DXF o in TIFF a
scala 10k o 2k .

Poiche dici che ti va bene anche il raster.
Sul sito di Regione Lombardia, a quesot link,

http://www.geoportale.regione.lombardia.it/ricerca?p_p_id=advancedsearch_WAR_geoportalemetadataportlet_INSTANCE_eTwms35MceOx_p_lifecycle=0_p_state=maximized_p_mode=view&_advancedsearch_WAR_geoportalemetadataportlet_INSTANCE_eTwms35MceOx_searchTerm=wms&_advancedsearch_WAR_geoportalemetadataportlet_INSTANCE_eTwms35MceOx_dataType=1&_advancedsearch_WAR_geoportalemetadataportlet_INSTANCE_eTwms35MceOx_showSearchFields=false

Trovresti il WMS del dbtopografico, che e' una base cartografica
paragonabile alla CTR.
Potresti provare a usare quella come base di sfondo nel tuo lavoro.

Stai attenta a impostare correttamente il sistema di riferimnto nella
connessione al wms,
perche' se sbagli , ci pensera' qgis a riproeittartelo e questo vuol dire
che introdurrsti un errore di spostamento del dato che potrebbe essere per
te inaccettabile.

Saluti,
A.

[Qgis-user] Info con QGIS Server and GeoPDF

[Andrea Peri]

Hi,
I'm using actually qgis server 2.18 version.

In this day I discovered the capabilities of QGIS desktop 3.x to export
GeoPDF formato.

I like to know if this capability to generate geopdf is also available in
qgis server 3.x to start to do some test,
And there is some docs on this capabilities on qgis server ?

Many thx,
Andrea Peri

Hi, afaik, internet and http is a sessionless protocol so i guess is quite
impossible to gdal understand that an user (another user) is using a file.
To have this kind of communication is use a messaging queue manager like
jboss.

This is my personal opinion.

Andrea.

Re: [Qgis-user] GeoPackage deadlocks

[Andrea Peri]

Hi,
Geopackage is an Exchange format. Is not affordable in a multiuser data
entry environment.
This require a dbms like postgres + postfis.

Andrea.

[Qgis-user] Disable on some service the GetLegendGraphics availability if possible

[Andrea Peri]

Hi,
On an our wms server we are using qgis-server version 2.18.

I notice that on some service with qgis-server the request
GetLegendGraphics take more than 120 seconds to response.
The time in reasonable because they serve huge data and the time to
calculate the legend is this.

But the question is that should be better to disable the GetLegendGraphics
on some of these service because in they the Legend is useless.

So , i like to know if is possible set qgis-server to do not report the
availablity of GetLegendGraphics as an available command in the
GetCapabilities response  (and of course disable the response to the
getlegendgraphics request) for some services (some qgis projects served
with qgis-server).

Thx for any help.

Great.

However for me is also curious why in my tests this not happened when the
wms was qgis server

Re: [Qgis-user] failed to add WMS layer

[Andrea Peri]

Hi,

I know the network plugin. It help me to understand this bug.

The bug is due to the wms provider that when you click on "add to map"
button try to read from the cache the capability info.

If te cache is to zero , in old qgis 2.18 the wms provider do another
request getcapabilities to the wms server to have it.
Instead in the qgis 3, if the cache if to zero, the request is not saved
and the read for add to map fail.

I notice this happen with mapserver and geosevrver, instead with
qgis-server don'.

The only explanation I can do is that for qgis-server it used a differente
code for provider wms.

Re: [Qgis-user] failed to add WMS layer

[Andrea Peri]

Are trying to Connect to qgis server?
I see the qgis dont have any issues to connect to qgis server.

Instead trying to connect to a  wms mapserver or to a wms geoserver.
I see the issue.

To reply
Cache setting size yo zero in
Qgis and try to add a map wms to canvas from a mapserver or geoserver

Please note that
The issue is when click on add to canvas not when connect to retrieve the
list of layers.

I have this issue on qgis 3.8.0 for windows 64 bit.

Have you the cache to zero size?
I discovered this kind of strangenissue some weeks ago

If the qgis cache size is turn to zero the capabilities fail when go to add
the map to the Canvas.
This issue is on only with some wms (mapserver, geoserver) do not with
qgisserver.

I dont know with arcgis rest services.

Re: [Qgis-user] Not valid data source on wms layer access for QGIS 3.8

Hi, Richard,

I like to reproduce what you are reporting me:

I like to understand better what is this.
But I don't understand what you mean with "opened that node on the browser"
. You mean a special browser inside QGIS ?

Many thx for help.

Re: [Qgis-user] Not valid data source on wms layer access for QGIS 3.8

[Andrea Peri]

Hi,
I load the network plugin and try with it.

I don't understand the result , but is why a really don't now how work
programmatically qgis.

I see when try to connetc to retrieve the list of layers , qgis send a
classic getcapabilities request.
This is the url invoked:
http://www502.regione.toscana.it/ows_ofc/com.rt.wms.RTmap/wms?map=owsofc=WMS=GetCapabilities

But when I try to add the choosed layer tothe map, I see from the network
plugin that qgis resend another getcapabilites request.
Sincerelly I don't understand why qgis is need to request still a
getcapabilites.
However meanwhile the first getcapabilies is read from network (this is
reported from the plugin), instead the second getcapabilies is taken from
the cache.
Infact, the plugin report me it is "used entry from cache".

I don't understand why this second getcapabilities is needed, but however I
have the cace set to ZERO.
I have this set because when I work to change sometimes on the wms server
to see the result I should empty the cache , so I prefer to have the cache
to zero. To have always the last from the network.

So I try to re-enable a lot of cache size.

AND NOW IT WORK.
But sincerelly I don't like to MUST HAVe ALWAYS the cache enabled to have a
workable wms.
Perhaps the real issue is to always use the cache without see that it is
set so ZERO.

However thx for the help.

Andrea.

[Qgis-user] Not valid data source on wms layer access for QGIS 3.8

[Andrea Peri]

Hi,

I have trouble using our wms services with QGIS 3.8.

As example:
our url:
http://www502.regione.toscana.it/ows_ofc/com.rt.wms.RTmap/wms?map=owsofc

When I try to add it to a map canvas the connection return le list of layer
.
Choosing one and using the EPSG:3003.
When Add to the canvas I see an error NOT VALID DATA SOURCE.

The same steps instead work correctly with the old QGIS 2.18.

Is this confirmed from some other one ?

Thx.
Andrea.

[Qgis-user] How time between two requests of a composer map

[Andrea Peri]

 I notice that often our try-ing to export a pdf from a qgis composer lost
some tile from wms layers.

I know thereis the number of requests and also the timeout. But I guess the
problem is instead due to a saturation of the request que due too much
requests send at the same time.

When the quer of the web server is full the other request simply was
rejected and I guess this is our case.

So a try I wan to do is to try to insert a wait-time between the send of
two tile requests when the composer do an export pdf retrieving the wms
layers.

I like to know if there is a workaround to insert this wait-time of instead
need to insert it by code.

Thx,

Andrea Peri.

Re: [Qgis-user] Are GetLegendGraphic ignoring BBOX?

[Andrea Peri]

The bbox is an evolution out of specs added to mapserver and to qgis-server
And also to qgis wms client to allow a legend with only the elements
available in the visible map (the bbox)

More info on mapserver where there isnthe specs of this evolution.

http://www502.regione.toscana.it/wmsraster/com.rt.wms.RTmap/wms?map=wmsambamm

With parameters:
epsg:3003, img/png

I have an error:

Layer not valid: Raster layer data source not valid (sorgente dati: wms,
URI:
contextualWMSLegend=0=EPSG:3003=7=10=image/png=rt_ambamm.idcomuni.rt.poly=
http://www502.regione.toscana.it/wmsraster/com.rt.wms.RTmap/wms?map%3Dwmsambamm


But when add from the same wms server using the QGIS 2.18.18 with the same
parameters it is added without any trouble.

Is available a more detailed log in QGIS 3.4 to understand why it refuse to
add my wms map ?

Thx.

[Qgis-user] QGIS-Server and Out-Of-Memory

[Andrea Peri]

Hi,
I have a qgis-server wms service (v. 2.18).

Sometime this service has gone the machine in out-of-memory.

I need tounderstand better what is happening and so I need some details.

My simple question is

QGIS-Server is using the swap space as memory or is set to use only memory
ram ?

A too big widht x heght image asked from some user could cause an
out-of-memory ?

Thx,
Andrea.

[Qgis-user] retrieve the Legend from wms using the SCALE parameter

[Andrea Peri]

Hi,
I notice that in qgis 2.18 and also in qgis 3.0
is not possible to retrieve the legend from the wms layer (using of course
the getLegendGraphic comand) apply-ing the SCALE parameter.

SCALE parameter is a STANDARD OGC parameter (optional) to retrieve the
legend
at the actual scale

QGIS allow to retrieve the legend using the the CONTEXTUAL option.
But it is anot standard parameter.
The contextual is of course more powerful but is a not standard and so not
always all the wms support it.

So' actually the only option is the standard getlegendgraphics that
retrieve without the scale parameter.

This some time give wrong lgends.

I report two eample.

The first is a good legend retrieved using the SCALE parameter from a wms
layer.

The second is a good example of what mean "sometime" retrieve the legend
without the scale parameter.

The second example repeat three time the same domain because there are
three different rendering at three scale interval.
Without the scale parameter the wms send ALL the legend for EVERY scale
interval.

The first example instead using the sCALE parameter obtain the right legend
for the scale of the MAP.

Re: [Qgis-user] GetLegendGraphics error truncate

[Andrea Peri]

I guess actually the content-type should be something like

"image/png"
or "image/png8"

It is ok for qgis ?

Re: [Qgis-user] Convert WMS Layer to Vector

[Andrea Peri]

Hi,
I agree with your response because richard ask for an entire dataset.

I like only add that if the user is likely to retrieve the single feature
it could try to do a
GetFeatureInfo (the identify of qgis) on the wms layer asking for "feature"
instead of "html"

The wms often return the geometry.

Regards,
Andrea

[Qgis-user] how duplicate the rendering of a value.

[Andrea Peri]

Hi,
I have a categorized rendering where every single render is quite complex.
To add new domain values at the list of rendering I like to duplicate
another domain and change the differences.

Is possible to do a copy/paste on a category rendering ?

I see the context menu show a copy/paste , but seem don't work.
I'm using 2.18.

Thx

Thx to both.

I rename the .qgis folder and try to editi using this new configuration.
Fortunatelly I do not need any plugin for my work. I use only a wms map to
retrace the geometries.

[Qgis-user] QGIS 2.18 freeze meanwhile editing

[Andrea Peri]

Hi,
I'm using qgis 2.18.
Every time I goin ediiting on a shapefile , after insert about 10 or 20
features it (the qgis) is freezing. Windows (I use win 7) report me qgis is
not responding and I need to kill it and restart.

I usually do not lost nothing because I know this and after every on insert
I save always the shapefile and the project.
But it is boring.
I like to know if this is a know issue of qgis or it could be a specific
issue of my qgis install.

I use qgis 2.18.18 (32 bit) but it happened also when I use 2.14 and
windows 7 64 bit.

Many thx.

[Qgis-user] How retrieve the scale value in a composer report

[Andrea Peri]

Hi,
I need to produce some reports using the composer and the Atlas.
In each of them I need to add the scale value.

So I try adding a textbox and the value $scale.
Unfortunately I see it return always 0 value.
This is confirmed in the help where is write that the $scale not
alwaysreturn the real scale value, but in some context it return 0 value.

There is some other choice to have the scale value in a composer+atlas
output ?

I'm using the qgis 2.18.

Many thx.

[Qgis-user] QGIS-Server: How support label in map-unit in both epsg:4326 and other projected srs

[Andrea Peri]

Hi,
I notice that QGIS when rendering a map in a projected srs and has labels
in map-unit need a value like (as example) "7" this need "do a label of 7
and scale it using the scale value.


But when the project is in epsg:4326 (a decimal degree unit system).
The value for the dimension of the labl in map-unit need to be more lower.
Infact using a value like 7 simply is too big and the label do not appear.

Instead appear if I use a value like 0,0004.

These difference are a big trouble when we pass to qgis-server.

Infact a wms allow the requests of map in a projected srs but also in a
geographical srs like epsg:4326.

These mean that a project server with qgis-server , in the label compoenent
dont work both in projected srs and decimal degree srs.

Should need a workaround to change the dimension of label when the user
request switch from a projected to a geographicsl srs.

So I like to know if someone has found some workaround to have this switch
automatically.

Many thx,
Andrea.

Re: [Qgis-user] QGIS ignore the cpg files when loading shapefiles ?

[Andrea Peri]

Hi,
I confirm .
The setting is at application level , not at project level.

I have my desktop set to "ignore setting", but when move to qgis-server it
don't use the cpg file.

So now I'm now changing manually all the layers one by one in my project
qgis from System to the effective charset of every single shapefile to use
them on qgis-server.

Re: [Qgis-user] QGIS ignore the cpg files when loading shapefiles ?

[Andrea Peri]

So in a QGIS desktop theuser can say to QGIS to use the CPG files,
and in QGIS-Server the user cannot say to qgis to use the CPG files, that
is so sistematically ignored.

Wow.

[Qgis-user] QGIS ignore the cpg files when loading shapefiles ?

[Andrea Peri]

Hi,
I'm using qgis 2.18
I have a charset probem .
So I try to create a cpg file and write on it UTF-8.
But nothing chance.

Instead if a go to properties, and change the CS from "system" to "UTF-8".
I see the labels have rightly reproduced.

I like to know if is confirmed that qgis is ignoring the cpg file.


Thx,
A.

Hi,



Is there a similar way as in ArcMap to visualize the vertexes of a polygon?
In ArcMap, by pressing ‘v’ I can see the vertexes during an edit session,
so I know where to snap to.

How can I visualize the vertexes in QGIS during an edit session?

Hi,

Is the "wms provider" adding always a parameter BGCOLOR=0xFF to
every GetMap request ?

I notice my maps have all the white color transparent.
I don't understand f it is a default of my wms server or is a hidden

[Qgis-user] Max size for a page print

[Andrea Peri]

Hi,
I notice in qgis composer is not possible to set a page size greater
than the max size of the printer installed drivers.

I guess this is a right choice when the output is directly to the
printer. But when the output is a PDF file or a Image file the limit
seem unuseful.

With the actual setting of QGIS to produce some PDF with large format
on a windows machine is need to install a driver for a large format
printer.
Unfortunatelly often this drivers refuse to install if there isn't
really the printer.

Any help is welcome.

Re: [Qgis-user] Editing a Postgis view

[Andrea Peri]

Hi Carlo.
Thx for response.

I 'm testing better.
But the strange is that the first write was regulrly executed.
If the view was really read-only it should refuse also the first write.

Instead only from the second write I have the error.

And the qgis don't report me a "readonly view.
But instead a "id primary key cannot be nul" constraint violation.

I try to understand better all of this.

Regards,

A.

Re: [Qgis-user] Editing a Postgis view

[Andrea Peri]

Hi Matthias,
thx for response.
So the trouble is in my db.

Now I try to understand better why it is not working.

This is my actual try test:

create table schemaapp.repository(
 ID serial primary key NOT NULL,
 UUID varchar(50) NOT NULL,
 PROGETTO varchar(9) NOT NULL,
 PROCEDIMENTO text NOT NULL,
 GEOMETRIA1 geometry(MULTIPOINT, 3003)
);


create view schemaapp.v_repository_point as
 select
  a.id as id,
  a.uuid as uuid,
  a.progetto as progetto,
  a.procedimento as procedimento,
  a.geometria1 as geometria
from
  schemappa.repository_wfs as a
where
  a.geometria1 is not null;

I will know if discover something.
thx again.

[Qgis-user] Editing a Postgis view

[Andrea Peri]

Hi,
I'm having some trouble to edit a postgis view using qgis.

The view is a simple:
select list-of-field from table1;

And the table1 is a table with a Primary key on a serial type field.

I add the first record and all was ok. The commit too.
When go to add the second record.
I start to have trouble.
The qgis report my always a constraint violation of the pk.
I try to leave the pk field empty, or try to fill it with a value.
No solution work.

So my question is if is confirmed that qgis (I use the 2.18) version)
is working in editing with a postgis view .

Thx.
A.

Hi,
I notice that the 2.16 (and 2.14) wrong to retrieve the legend from a
GetLegendGraphics when the defaut style is not name as "default".

afaik the ogc specs don't require mandatory the default style named "default".
So Iguess this more probably is an issue of qgis wms provider.

I like some thought or confirm before issue a ticket.

Re: [Qgis-user] Wrong retrieving of wms legend

[Andrea Peri]

Hi Richard.
Effectivelly I tested your wms and using it the legend is correctly
retrieved only for the layer choose.
I use qgis 2.16.1.
After I re-test my original url:
(this)
http://www502.regione.toscana.it/wmsraster/com.rt.wms.RTmap/wms?map=wmsofc

And again I see the qgis retrieve ALL the legend of all the layers.
I tested other wms of our set of wms service and seem only this has
that problem.

So I do some more proof tested.

And found where is the ISSUE.
QGIS wrong to get the legend when the layer wms requested HAS NOT A LEGEND.
Infact the issu happened when I ask any layer of our wms that is a
RASTER LAYER with no legend defined.
Instead not happened when the layer wms is of a vector dataset (where
the legend happened).

SO If you whould test and see the issue you should use our wms service:
http://www502.regione.toscana.it/wmsraster/com.rt.wms.RTmap/wms?map=wmsofc

and choose the layer
rt_ofc.1954

that return the orthophoto imagery of the year 1954.
With this layer the qgis will retrieve ALL the legends of the wms service.

Instead if you choose the layer
rt_ofc.1954.qu
that is a vector dataset (quadre of union)
qgis correctly retrieve only its own legend.

Please can you confirm this ?

Thx

A.

[Qgis-user] Wrong retrieving of wms legend

[Andrea Peri]

Hi,
I notive that in the qgis 2.14.5 and in the qgis 2.16.1
when adding a layer wms choosing from a list of layers available in
the wms service connected,
qgis retrieve as legend of the layer ALL the legends of all the wms
layer available in the wms service.
Using the 2.8 QGIS version, the legend is retrieve correctly (only the
layer choosed).

Someone can confirm this as an issue ?

thx.

[Qgis-user] How set default as "show all features"

[Andrea Peri]

Hi,
When start qgis is always starting with option "show feature visible
on map" in attribute windows.
I know is possible to change it to "show all features".
But when I close qgis and restart it it return to original setting
"show feature visible on map".

The option "show feature visible on map".

Too much times our users give us some datasets where there is hidden
wrong records because outside from visibility box.

These happened because our users forgot to set the "show all features"
and so dont see the wrong records to delete.
:(

There is a configure solution to set qgis to start always with option
"show all features" ?

Thx.

If the identify is disabled, it mean that actually your mapfile of
mapserver is not set to allow a getfeatureinfo response.

I verify the 2.14 released with source.
There isnt the epsg:6707.
So it is not alligned to the epsg-db 8.4

I don't undesratn why the OSGEO version of the same QGIS 2.14 is

Any explanation is welcome

Re: [Qgis-user] Trouble with a qgis project for qgis-server

[Andrea Peri]

Hi,
Perhaps I found the issue.
The QGIS on our server is a QGIS 2.14 but has some difference at srs level .
Infact the srs.db has not the EPSG:6707 definition that i sused by our datasets.
The EPSG:6707 is instead available in the windows version of qgis.

I verify also that the proj installed in the same server has that definition.
So the trouble is that the compile procedure more probably don't load
that definition.

Hi,
I found the issue !

The error born when setting the SHORT-NAME in the metadata section of layer.

I test it on qgis 2.14.5 as client and 2.14.3 as qgis-server.
I dont know if is an issue of QGIS desktop side or of qgis-server side.

Please, someone can confirm this issue ?

[Qgis-user] QGIS don't understand the geometry from getfeatureinfo of a qgis-server

[Andrea Peri]

Hi,
We have two main wms systems.
The first is with a mapserver.
The second is with a qgis-server 2.14.

Using qgis 2.14 as a wms client on my desktop, when connect to the
mapserver and do a GetFeatureInfo from a layer of mapserver.
I receive the information and if I swith to the "feature response" I
can see the geometry painted in the canvas thx to the GML retrieved
from the getfeatureinfo response.

When connect to the qgis-server 2.14 add a layer and do a
GetFeatureInfo from a layer of our qgis-server, I receive the
information and if I switch to the "feature response" I can read the
GML in the list of attributes, BUT I DONT HAVE any polygon geometry
painted in the canvas.

I try also to check the options "add geometry to feature response" in
server settings page, but no change to this.

Is confirmed that QGIS client don't recognize at vector level the GML
from a QGIS-Server getfetureinfo response ?

Thx in advance.

Is it available in some other part of qgis menus or an issue ?

[Qgis-user] Shapefile with file .cpg(codepage)

[Andrea Peri]

Hi,
I have some shapefiles with an extra file having extension .cpg.
The .cpg extension is a optional extension for declaration of Code-Page.
Is this file knowed and supported from QGIS 2.14. ?

I don't know if the qgis when loading a shapefile is using the ogr or
instead is using an own shapefile provider, but however I don't know
if gdal is knowing and using this .cpg file.
:)

Re: [Qgis-user] Is QGIS showing the records with geometry NULL

[Andrea Peri]

Hi Jukka,
yes is exactly this the question.

The QGIS don't show any record with null geometry so is impossible for
me to add a geometry to it. Or delete it definitivelly.

But the record with null geometry is however saved when I export the
shapefile from qgis.

So the QGIS show me 14 records but export a shapefile with 16 records
(2 records has null geometry).

So when load it in a spatialite or on a postgis environment or open it
using another GIS like arcview3 from esri.
I see this two more records with null geometry.

AFAIK this is a chaotic situation for who work using qgis and produce
a shapefile to distribute to other users that has other gis softwares.

[Qgis-user] Is QGIS showing the records with geometry NULL

[Andrea Peri]

Hi,
I have a shapefile with 164 records where 2 records have null geometry.

When load on qgis 2.14.2 it show me only a table with 162 records.
I try to set the show all fature in initial extent but no result.
The two geometry null records are not showed.

Any hint on this ?

Re: [Qgis-user] Clip - unsupported geometrytype -2147483646

Some time the intersection of two polygon geometry could generate a
multipolygon or also a linestring or also a point result or also a
collection of all the previous type.
Nothing is wrong this happen when the geometria are not true topological.

Hi,

Trying to clip a vector line layer with a vector polygon layer I get an
error

“Input layer has unsupported geometry type -2147483646”



Both layers has the same CRS

Both layers are checked for illegal geometry.



Earlier today I performed same action with data created in QGIS and with a
perfect result.

The data look similar in the browser – metatdata.

Any suggestion to what might be wrong.

[Qgis-user] Qgis what epsg text file is using

[Andrea Peri]

Hi,
For our internal use i need customize the epsg file of the PROJ.
I customize the epsg of the PROJ installed in the path /usr/loca/
But it seem dont be used from the qgis that still is doing as if the epsg
was not changed.
So i guess the qgis could use an its own internal PROJ or an its internal
epsg file.
If this is true, i like to know where is stored the epsg information for
proj
To be able to customize also they.

Every info is welcome,
Thx

[Qgis-user] qgis 2.14 dont start grass

[Andrea Peri]

Hi,
my qgis 2.14 from install offline or from osgeo4w 32bit
will not start any toold from grass.
It report always this message:


Missing dependency. This algorithm cannot be run :-(

GRASS GIS 7 folder is not configured. Please configure it before
running GRASS GIS 7 algorithms.


I try the standalone install version 2.14 or 2.12.
I try also the 2.14 from osgeo4w.

Is this confirmed or it could be a local problem of my window pc ?

[Qgis-user] QGIS will display invalid geometries when under their extent ?

[Andrea Peri]

Hi,
I report some days ago about a trouble on a line geometry that will
disappear when zoom.
So I open a ticket with a sample.

http://hub.qgis.org/issues/14524

In the discussion will say that qgis could not be able to display any
invalid geometry (disabling it ?) when the extent is molesser then
canvas extent.

I need to know if this is true.
Because this mean that with QGIS WILL NEVER possible to resolve an
invalid geometry editing it.
This beacause qgis simply remove it when zoom forward the invalid vertex point.

I need to know if this is true or a miss something.

thx.

[Qgis-user] Disappearing line

[Andrea Peri]

Hi,
We have a line shapefile produced with qgis with some strange issue.
When add it to a new empty qgis project and show at  full extent it is visible.
Instead , when zoom at details it simply disapplear.

I never seen this before.

So I open an issue and try to add the shapefile to the ticket. (it is
about 300kb) so perhaps could not possible to add.
Bu I'like to know if someone before now has seen this really strange issue.

The shapefile is with 1 only records multilinestring .
Obtained manually from we with many day of editing work at big details
(about 1:2000) and after this dissolved into 1 only geometry with many
parts.
After this dissolve it work again for some day, where we apply others editing.
And yesterdays we dont know we it start to do this strange
disappearing at the details level.

Any information is welcome.

Just another little update.

I try to analyze the new shapefile with the invalidity resolved, using

crash.

Now I add this new shapefile to the ticket.

Re: [Qgis-user] Disappearing line

[Andrea Peri]

Thx for feedback.

We have not a solution inside QGIS to resolve this problem, because
when zoom to details the canvas stop to showing it.

The problem is that this kind of problem is born inside QGIS meanwhile
editing it.

After this issue was born in editing session , the shapefile is no
more editable on qgis because it is unusable at details.

Unfortunatelly we have no other GIS solution othe than QGIS so we are
searching a solution to resolve it.

Now I try to load it inside a spatialite environment and do a
MakeValid hoping this could resolve it definitivelly.

Thx again,

A.
