# An Optimized Rubber-Sheet Algorithm for Continuous Area Cartograms

@article{Sun2013AnOR, title={An Optimized Rubber-Sheet Algorithm for Continuous Area Cartograms}, author={Shipeng Sun}, journal={The Professional Geographer}, year={2013}, volume={65}, pages={16 - 30} }

This article optimizes a continuous area cartogram algorithm published in The Professional Geographer by Dougenik, Chrisman, and Niemeyer (DCN) in 1985. The DCN algorithm simulates a rubber sheet and is an iterative and approximate solution of cartogram construction. Although it remains popular because of its conceptual simplicity and cartographic quality, the DCN algorithm cannot completely preserve topology and its mathematical properties are inadequately explained. This article presents an…
