Golden Software's Surfer software is a full-function 3D visualization, contouring and surface modeling package that runs under MS Windows. Surfer is used extensively for terrain modeling, gridding, surface analysis, landscape visualization, contour mapping, 3D surface mapping, volumetrics, and much more. Surfer's sophisticated interpolation engine transforms your XYZ data into publication-quality maps. Surfer provides more gridding methods and more control over gridding parameters, including customized variograms, than any other software package on the market. You can also use grid files obtained from other sources, such as USGS DEM files or ESRI grid files. Display your grid as outstanding contour maps, 3D maps, 3D wireframe, vector, image, shaded relief, and post maps. Add base maps and combine map types to create the most informative display possible. Virtually all aspects of your maps can be customized to produce exactly the presentation you want. Generating publication quality maps has never been quicker or easier.
