My problem is that I am trying to export some rasters to Rockworks so that I can create a sand layer from them. Rockworks requires the grid files i use to have the exact same XY co-ordinates.
So i have a polygon of my sand layer - I create one raster of the surface (by using extract by mask from some AHN data I have) and the second one i create myself with a depth of -10.
When i check their layer properties however they are different! e.g. the top extent of the lower raster is
503002.235094748 and the top extent of the upper raster is
503000.235094748. The left and bottom extents are exactly the same..
They're both in the same co-ordinate system..?!
