Compressing terrain datasets using segmentation
W. Randolph Franklin, Metin Inanc · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2006
We propose a novel compression scheme to achieve lossy compression of elevation datasets. Our scheme does not use predictors in the traditional sense. Our predictors are based on planar dataset segments. We believe that this is a far better way of expressing context in an elevation dataset since it can capture continuities in different geometries and allows us to provide an error bound on the output.
