OpenTopography v 3.2 Release Adds TIN-Based Gridding

The TIN (Triangulated Irregular Network) interpolation function now offered by OpenTopography uses Martin Isenburg’s high-performance code for generating raster digital elevation models (DEMs) from mass points via streaming Delaunay triangulation. A TIN model represents the landscape as a surface composed of contiguous and non-overlapping triangles constructed between the cloud of lidar returns. Within each triangle the surface is represented by a plane. A raster DEM is then constructed by sampling the triangulated surface elevation at the DEM nodes. More information on Isenburg’s streaming TIN is available at: http://www.cs.unc.edu/~isenburg/tin2dem/ and in the following publication: Read More
