Rasters not stylized #148

nothing-butanol · 2015-11-03T04:30:50Z

I may have done something wrong but when I try to add a raster with a defined pseudocolor band all I get is a black box for the extent of the raster. The raster should be yellow to red scaled. Not sure if it is a bug or I am not setting it up correctly. Using QGIS 2.8 and the raster is a .tif file created from the Heatmap tool.

tomchadwin · 2015-11-03T09:08:14Z

Yes. The plugin works on the input image, not the styled output. This issue remains from qgis2leaf (Geolicious/qgis2leaf#168). I believe qgis-ol3 did the same, so the issue potentially exists for both formats - perhaps you could confirm or deny whether OL3 export fails in the same way?

Not working, but I don't understand why - any ideas, anyone?

tomchadwin · 2016-01-05T11:31:48Z

I've started work on this in a new branch (https://github.com/tomchadwin/qgis2web/tree/rendered-raster). Not working yet, so any help would be most welcome.

tomchadwin · 2016-01-07T17:06:09Z

I've not made any progress on this, so I've asked for help: http://gis.stackexchange.com/questions/175952/pyqgis-save-raster-as-rendered-image-then-use-gdal-tools-on-it

#148

tomchadwin · 2016-02-02T12:26:42Z

OK, as far as I can see, there are four different ways of calling GDAL:

os.system() - not recommended
subprocess.call()/subprocess.popen() - we used to do it this way, at least in the OL3 raster export
processing.runalg() - how we do it now
Python GDAL bindings - never tried this

I wonder if the GDAL bindings might be worth exploring. Since I don't know what has caused previous attempts to fail, I don't know what I'm looking for. Can anyone explain the pros and cons of the approaches above?

pcav · 2016-04-02T13:01:15Z

Confirmed here, both on OL3 and on leaflet: a coloured DTM turns out as grayscale.

pcav · 2016-04-02T13:05:36Z

I'm using a sample project (geomorpho) and data from:
https://github.com/qgis/QGIS-Documentation/tree/master/source/docs/training_manual/exercise_data/processing/more_backends

lucacasagrande · 2016-06-15T18:14:00Z

I will take a look.

tomchadwin · 2016-06-16T07:21:50Z

Thanks, @lucacasagrande!

lucacasagrande · 2016-06-19T21:13:14Z

Update: Style is working with OL3 (with QGIS-master).

tomchadwin · 2016-06-20T12:40:53Z

Only with master? Not working for me with a nightly from a couple of weeks ago:

qgis/QGIS@94d88e6

tomchadwin · 2016-06-20T13:19:34Z

No, I can't get this to work:

Downloaded latest nightly
Loaded singleband greyscale raster
Applied pseudocolour style
qgis2web

I see nothing on screen. Are we not describing the same thing?

lucacasagrande · 2016-06-20T15:54:39Z

Yes Tom.
In master (next 2.15 I think) some of the algorithms parameters, needed to use raster, have been modified.

lucacasagrande · 2016-06-21T05:46:27Z

Update: Style is working also in LeafletJS.

tomchadwin · 2016-06-21T10:00:56Z

Sorry, @lucacasagrande. I couldn't see any commits/PRs, so I thought you were talking about tomchadwin/qgis2web master as well as QGIS master.

lucacasagrande · 2016-06-21T18:04:50Z

Hi @tomchadwin I can make a pull request, but it's better in a specific branch because currently it's working only with QGIS-master. Tomorrow I will start to work on a solution to make it compatible with old version.

tomchadwin · 2016-06-21T18:11:20Z

Now I understand. Sorry for being so slow. Do you need me to branch here (git non-expert)?

lucacasagrande · 2016-06-21T20:11:23Z

No problem Tom 👍
Probably we don't need another branch..I have modified the code and now rasters work fine also in 2.14.3. I will do some more tests and I will make the pull request.

tomchadwin · 2016-06-21T22:25:19Z

Wow, that was quick.

On a related topic, I've upped the minimum supported QGIS version to 2.8. I would be prepared to up it to 2.14 once that becomes LTR - pretty soon.

lucacasagrande · 2016-06-25T13:41:19Z

Please test if we can close this issue. Thanks :)

tomchadwin · 2016-06-28T20:09:04Z

Fix committed to master. Please test. @pcav, can you test?

tomchadwin · 2016-06-28T21:05:16Z

Released as 1.10.0-FOSS4GUK2016 experimental and pushed to QGIS plugins repo.

zkuralt · 2016-09-28T12:52:57Z

Hi!

I got this error when trying to add raster layers (GTiff) to map. There is no problem with vector layers.

I am using QGIS 2.16.2 on Mac. I will try same thing on Windows computer to see if that could be a problem.

tomchadwin · 2016-09-28T13:12:38Z

Can you see if you can find more info in the main QGIS log: View > Panels > Log messages panel?

zkuralt · 2016-09-28T13:31:05Z

That should be it. On windows machine it kind of works (raster resolution is degraded). I can share files that I'm using.

tomchadwin · 2016-10-03T13:53:19Z

Are you able to find out which version of GDAL you are using?

zkuralt · 2016-10-03T14:00:14Z

Does this answer your question?

tomchadwin · 2016-12-21T17:58:54Z

@zkuralt Is this still an issue?

zkuralt · 2016-12-22T08:37:37Z

Yes, I am still not able to add raster layers to map. Vector layers work fine. (working on MacOS, QGIS 2.18.0)

tomchadwin · 2016-12-22T09:20:35Z

Leaflet or OpenLayers 3 export (or both)?

zkuralt · 2016-12-23T19:38:52Z

I get the same error when trying to add raster layer (before export). After export to OpenLayers 3 there is no sign of the raster layer, but when I export it to Leaflet, there is at least something indicating that there is some layer (screenshot attached).

#148

tomchadwin · 2017-05-10T12:45:17Z

@zkuralt I've just made a change to the raster code. Are you able to download master branch and try again? Let us know what happens.

zkuralt · 2017-05-10T13:20:57Z

Seems to be working both with vectors and rasters. I am attaching test webmap I just made.

tomchadwin · 2017-05-10T13:33:03Z

Fantastic news! Thanks for getting back to me so quickly.

It'll be a pleasure to close this issue after so long.

aperezrivoira · 2017-05-15T16:21:18Z

Tom, in relation to my previous inquiry on this topic, I am still getting a similar error as described earlier on this post: not being able to export raster with qgis2web plugin.
One thing I noticed with the last version of the plugin, is that it takes a while to load.
Attached is one of the rasters I used (please change file extension .zip for .tif), and here are the Processing and qgis2web Logs:
