Weighted Isolines: An Alternative Method for Depicting Statistical SurfacesFootnote∗

∗This project was supported by a Pennsylvania State University College of Earth and Mineral Sciences faculty research grant. Andrew Green (now a cartographer with GeoSystems, Lancaster PA) and Peter Wrenn (now a cartographer with Michelin Travel Publications, Greenville SC) contributed to a preliminary study while they were undergraduate students at The Pennsylvania State University.
