I’ve this grid creation assignment where 16 horizons plus seafloor have been mapped. The problem is the surveys did not cover all areas of interest. So some portions of the area to be gridded do not have seismic trace data. I want to extrapolate and or interpolate where necessary. My question is, is it possible to use the X,Y,Z points under Grids in Kingdom to digitize points on the basemap. The geologist exported the horizon data *.dat with missing xyz data in some place just because there was no seismic data.
