DMS Software R-WEL, Inc . The Desktop Mapping System provides a rigorous softcopy photogrammetric solution for use with scanned aerial photographs. Stereomodels are viewed in anaglyph 3D for topographic mapping, map compilation and map revision. The stereomodels may also be employed for DEM generation using automated stereocorrelation techniques. Raster images can be zoomed and X, Y, and Z map coordinates, pixel and line coordinates and digital number values recovered by moving the cursor throughout the image.
Image enhancements maximize image contrast and improve interpretability for mapping applications.
A typical application of the IHS Transformation is to create a high resolution color image by integrating SPOT Panchromatic data with SPOT XS or Landsat Thematic Mapper multispectral image data. The development of registered image data sets for use in GIS applications is automated and readily accomplished. Vector files can be established by tracing point, line and polygon features from an image on the display screen. In addition, existing map files in vector format can be overlaid on an image or GIS file for the purpose of map revision or accuracy checking. After a stereo model is formed, it can be viewed in 3D and a floating mark employed to measure planimetric map coordinates and elevations.
