We describe several past and proposed projects for converting
elevation data to different formats, such as gridded, TIN, and
spline, lossily compressing, applying to visibility and drainage
to test the compression quality, and integrating everything into a
test suite.

Keywords: TIN, Triangulated Irregular Network, gridded elevation
data, lossy compression, visibility indices.

Presented at a Dagstuhl (Germany) workshop on Computational
