I have created an ESRI grid from LIDAR data, after first processing grids in Surfer. But, based on the spacing I specified in Surfer, there are gaps (NoData) in the ESRI grid created from the "ground-surface" returns, due to the building locations (in the unclassified return). Can someone help me figure out how to fill in these gaps (of NoData), likely with the "nearest neighbors"?
