In this poster presentation, we describe how the PINGPONG program (FOSS distributed under the GPL) has been used to implement a quality control procedure for laser scanned DEMs. The approach used is independent of navigational (GPS/INS) data and ground control points.

Fundamentally, PINGPONG is a high speed gridding program for scattered geodata. It uses a simple, but efficient, data management technique to speed up the gridding procedure.
