[Qgis-developer] A new plugin has been created by 3nids.

[Denis Rouzaud]

Yes, exactly.

I am using DTM to calculate pipe slopes. If you have very short pipes 
crossing two raster cells, you will get a wrong value, this is why I 
needed to calculate interpolated values.

You can choose:
- nearest neighbor
- bi-linear using 4 cells
- bi-cubic using 16 cells (I did not notive slow down, but it requires 
scipy)

Also, the plugin saved directly the values in the vector layer (instead 
of creating a new shapefile).

Cheers,

Denis
