Augmenting Grid-Based Contours to Improve Thin-Plate DEM Generation
We present two new pre-processing techniques that improve thin plate Digital Elevation Model (DEM) approximations from grid-based contour data. One method computes gradients from an initialExpand

Converting Elevation Contours to a Grid
We present two new methods for approximating elevation data from contours to a grid. The first repeatedly interpolates new contour lines between the original ones. The second starts with anyExpand
