[Qgis-user] Interpolation plugin error message

[antonio scotti]

 Hi, 
many thanks for all the suggestions.I found out that the menu Raster->Analisis->Grid (Interpolation) has a similar funtionality that the one I was looking for so I could do the DEM eventually.
Now another little issue happened. The created DEM is in gray scale colors. I'd like to give it other colors to better differentiate the various elevations. When I use the style dialog and I choose a pseudocolor color scale and spectrum type....after I click ok the DEM desappears from view and only the clipped-contours layer remains (as before building the DEM)Any ideas why this happens and how can I get the spectral coloring?Regards

Hi,
thanks for your reply. I found a couple ofGRASS utilities that do interpolation in the processes toolbox. I triedto run one of these but receive a message saying that GRASS in not correclyinstalled

Hi,
from my experiences longer ago, the interpolationplugin is not really easy to use and seems not to be maintained/enhancedfor a long time.

Maybe you can find a substitute for yourinterpolation tasks in the Processing toolbox?

Cheers
Bernd

Hi all, I am new to this forum and to QGIS
I am trying to construct a DEM from contourlines by using QGIS 2.14.0.
I am doing this by using a clip rectangleon top of the contour lines and interpolating, by using the interpolationplugin

After I enter the data in the interpolationdialog and clic Save  I get an exception (se attached file). 
Any help appreciated

Best regards
