[Qgis-user] Problem with jpg file as raster layer (libjpeg-error)
Hello all, I use qgis from time to time, now (with qgis 2.8.2, win 7 64) I get an error notice, when I want to add a new raster file (a jpg ortho photo): No supported data format: Raster layer: the file is no supported raster data source libjpeg: Invalid comonent in ID 0 in SOS or No supported data format: Raster layer: the file is no supported raster data source libjpeg: Bogus Huffman table definition But I can open this file with old qgis 1.8.0., and other photos from same type also with 2.8.2. Does anyone know a solution? Can I check the ligjpeg version anywhere or do I have to update something? Thanks a lot, BR Jrg Kalz-Kaprolat ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] GRASS7 algorithms not working
Hi everyone, I have a problem, when I updated from QGIS 2.8 to the new 2.10 version, the algorithms of GRASS7 in the processor are not working anymore. The message says The depency is not satisfied. I have uninstalled and installed again QGIS but with no results, and of course I have installed and I have working GRASS7. I'm using Ubuntu Mate 14.04. Anyone has some idea? Thanks!!! ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] Adding a Oracle Spatial Layer without a SRID Value at the geometry column
Hi, we have some problems to add a oracle spatial layer in QGIS. Following situation at our oracle spatial database (Oracle 11g): The Database-Table has an index on the geometry column, but no declared primary key. Caused by a false EPSG 25833 system, the geometry column has no SRID value. Following reaction of qgis 2.11 Nightly (QGIS e679b0b): The Database-Table is identified as a spatial layer with the SRID -1, the correct geometry type and can be added as a layer. After adding I don't see any objects in qgis. I've got following notice in the protocols: *Protocol Qt* /2015-07-14T16:11:441 ..\..\..\..\..\..\..\src\providers\oracle\ocispatial\qsql_ocispatial.cpp: 3011: (QOCISpatialResult::gotoNext) goto next error: [ORA-00932: Inkonsistente Datentypen: BLOB erwartet, ARRAY erhalten]/ *Protocol Oracle* /2015-07-14T16:11:191 Oracle SRID -1 nicht gefunden./ If I delete the index from the geometry column at the oracle database, add a new srid value (faked EPSG 325833), add a new index on the column the problem is solved. Is there any way to solve the problems without changes at the main oracle spatial database. Due to dependencies to a second GIS product it's not possible to update the entire database atm. What can i do?

Re: [Qgis-user] rivers growing in size as they go downhill
Ciao Luca, if you mean cutting the stream and manually assigning a width to every arc, well, it's not the right procedure anyway, but if you deal with a network as a network you should allow waterflow grow for other reasons besides going downhill. Every node brings affluents so more water becomes a bigger stream. So classifying the rank of the network is the proper thing to do. You don't have to do it manually, it's a directed planar graph so there are tools to deal with it (plugings and processing). If you look at old cartography, you may argue streams grow gradually and that is true, but there are tiny gutters and invisible kennels feeding them... Yes you may desire to kill all hydrologists, but this is a graph and the easiest thing is assuming the size of the stream depends on the rank of the starting node. You may also assume some intelligence in the tools you use may provide som help. It's more convenient to keep your streams in a network conscious database like spatialite instead of storing into shapefiles. c On Tue, 14 Jul 2015 at 22:08:45, luca.galupp...@gmail.com wrote: Dear all i have this idea of rendering a river network so that each river starts as a very thin blue line, and the line width increases little by little as the river goes. i wouldn't like to modify the original file (eg cutting rivers in pieces and give a different width to each piece) but all rivers are digitized with the right direction so i was wondering if there is an expression to teach qgis what is the start end of a river, and assign a wider line for any given distance, for example: from start to 200m - line width 0.1 from 200m to 400m - line width 0.2 from 400m and over - line width 0.3 i think this is an interesting problem because i cannot find a from - to command in qgis expression language, neither i know how to properly exploit the line direction with code, which would come useful in many other ways... any python expert out there can help? -- next part -- An HTML attachment was scrubbed...

Re: [Qgis-user] Handle Bad Layers
Hi Chandler, Since the last opening, have you either moved the files or renamed one of their (up)folders or moved the project. The Handle bad layers window pops up when QGIS doen't find the layer where it is intended to be (in absolute or relative path), mostly because the path to the file has changed or access is denied. You just have to select the row and type in the right path or use the browser to reach the new location and all is ok. But since these files are still on your disk, you should be able to open them in another project, unless they're damaged. What kinf of files are you trying to open? Regards, DelazJ 2015-07-15 1:35 GMT+02:00 Chandler Coleman chandc...@gmail.com: I am opening a project and a Handle Bad Layers window opens. It shows me 12 layers that have a bad handle. Why would I get this? I have open this project up many times without issue. Why are these layers now longer opening? I tried opening each layer independently in a new project but tells be the layers are bad. Why these 12 layers and not the other layers that were in the project?

Re: [Qgis-user] rivers growing in size as they go downhill
Ciao Carlo, I’m a new QGIS user, I’m intrigued by your last paragraph: You may also assume some intelligence in the tools you use may provide som help. It's more convenient to keep your streams in a network conscious database like spatialite instead of storing into shapefiles. Can you elaborate on the meaning of “network conscious database” or point me to some links to get me started, this sounds like a very useful capability. Martin.

[Qgis-user] QGIS instalation and uninstallation issues
Dear QGIS users My name is Evanilton Edgar Serrão Pires, I am an Environmental Engineering student and a QGIS user. I started to use QGIS 2.2.0 Valmiera last year and since my first installation it never installed GRASS and SAGA correctly (their shortcut never appeared correctly and never worked, therefore I could never use those applications inside QGIS) . At that time I was using Windows 8. When I started QGIS it appeared a dialogue box saying «QGIS couldn't find your GRASS installation. Would you like to specify path (GISBASE) to your GRASS installation?». And inside QGIS, SAGA and GRASS algorithms never worked properly. With the new releases of QGIS 2.4.0 Chugiak and 2.6.0 Brighton, when uninstalling, it would uninstall and install normally, however, always telling me that the previous version was already installed at the time of the installation, although I uninstalled it previously. Early this year, I bought a new computer (which came with Windows 8.1 Single Language) and I installed QGIS 2.8.1 Wien in first place (the first app to be installed right when I bought the computer, after the anti-virus, of course) and for my joy, it installed GRASS and SAGA correctly and was working very well, in such way that I was very happy with it. However, on the 25th of May, I uninstalled the 2.8.1 version and installed the 2.8.2, but for my displeasure, the GRASS and SAGA plugins were not properly installed again. I went to the QGIS project website looking for solutions and I found a page saying that I should specify the path for the ''.exe'', but in the program folder there is no executor file. I even installed GRASS independently again and in the new installation folder there is no ''.exe'' either. When I install SAGA independently it does not work with QGIS. Another strange thing is that after I have uninstalled the 2.8.1 version and tried to install the 2.8.2, for the first time when installing it appeared the information of skipping all the folder creations and extractions, and at the end it said that QGIS was installed but the application did not exist in my computer. When I installed for the second time, it extracted and created the folders, and when finished QGIS was in my computer. Attached you may find the file it produced in the first attempt. I always install using the standalone-installer. If you need any further information, please let me know. What should I do? Is it normal for the software never be completely removed from the system? Please, I really would like to solve this issue. Hope to hear from you soon. QGIS is really good and useful, and I think we should promote its development.
