[Qgis-user] How to probe raster values?
Hi Everybody! I'm working on a plugin in Python and I can't find any way to read values (at specified coordinates) from raster layers. I've tried with identify method of QgsRasterLayer object, but it's unavailable in my QGIS 0.10. Is this method depreciated, or only there is no Python binding for it yet? Is there any other way, or is that my time for switch to C? :) Regards, Borys. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] How to probe raster values?
Borys, What about using GDAL to access your raster values? Your plugin could get all the needed info (i.e. path, name, etc), load the data using GDAL, and read the data as needed using ReadRaster. Check out: http://www.gdal.org/gdal_tutorial.html or http://www.nabble.com/beginners-programming-questions-td15498345.html for details. Cheers, Carson Borys Jurgiel wrote: Hi Everybody!

Thanks Carson, just knowing that this is an R console is enough. Now, after making a simple plot(), I'm just dreaming: if we could display sp objects directly, not only avoiding the intermediate shp file but being able of plotting columns of the dataframe as statistical graphics in R... and soon being able to interact between the R plot and the geographic display (a linked brushing, for example), tools like in GeoDa but with a real GIS diaplay...
