Hi Alisson
I'm trying to export surface from stratigraphy model to MODFLOW, but I couldn't convert Rwgrd in grd....First, I've tried to convert in shapefile, but data went to there as polygon... I can't interpolate polygon as raster in GIS .... So it's a messy..... I need a file as grid (interpolate surface) to build my model in MODFLOW .... Can you help me?
