[Qgis-user] Geostats tool (bathymetry)

[Carlos Cerdán]

If your vector is a point layer, you can use "point sampling tool"
extension to get bathymetric values from both layers (vector and raster) so
you can compare them.

If your vector is a line layer you must rasterize it and cross them with
the raster calculator.

Good luck
