GPArc - is a powerful but easy to learn mapping tool. It allows for up to 100 layers which can be comprised of point, line and polygon SHP files, DXF, DGN and DWG Cad files, or TIFF, JPG and BMP raster images. It also allows the user to import ASCII files and supports .XZO exclusion zones. Imported ASCII files can be transformed in almost any conceivable manner. GPArc features an image registration utility which creates world files or transforms existing ones. GPArc is based on the ArcObjects libraries. These are the same libraries that the ESRI products, ArcInfo and ArcView are built on and therefore allow exceptional rendering and editing capabilities.
