I tried with your shapefile, and got no errors. Here are the steps... First I created a new GRASS location matching the CRS of the shapefile:
grass -c Coal-Test-Shapefile-main/coal_test.shp /home/micha/GIS/grass/michaela Check the projection: g.proj -p -PROJ_INFO------------------------------------------------- name : RD/83 / 3-degree Gauss-Kruger zone 5 ellps : bessel proj : tmerc lat_0 : 0 lon_0 : 15 k : 1 x_0 : 5500000 y_0 : 0 no_defs : defined -PROJ_EPSG------------------------------------------------- epsg : 3399 -PROJ_UNITS------------------------------------------------ unit : meter units : meters meters : 1 Then I imported your shapefile, and *set the computational region*: v.import Coal-Test-Shapefile-main/coal_test.shp output=coal_test g.region -ap vect=coal_test # Resolution is 1 meter, 1500x1500 pixels Now run the IDW module v.surf.idw input=coal colu=dbl_1 out=coal_idw_1 81 points loaded Interpolating raster map <coal_idw_1> (1500 rows, 1500 columns)... 100% v.surf.idw complete. Resulting image is attached. You can try other options to v.surf.idw to get a smoother interpolation, if necessary.
