Hi
I am not an expert QGIS user, I have downloaded a map from USGS, have created a
raster file with Raster > Extraction > Clipper.
In a layer called Junctions I want to add elevations automatically from this
raster file, by Plugins > Raster interpolation. It seems it is working, there
is a message saying that the data have been updated. But in reality no data is
updated and the following error message appears:
Traceback (most recent call last):
File
"/Users/francescoliva/.qgis2/python/plugins/rasterinterpolation/qgiscombomanager/layercombo.py",
line 102, in __canvasLayersChanged
for layerId, layer in
QgsMapLayerRegistry.instance().mapLayers().iteritems():
AttributeError: 'NoneType' object has no attribute 'instance'
Moreover When I open the Plugins > Raster interpolation, the window is not
showing all layers, one layer called Junctions_3 is not appearing.
Can you help me, thankyou
Best Regards
Francesco Liva
