Map Edit

Open Press OK

Creation of spatial digital database by digitization of existing maps and other data sources is one of the important functions in GIS. Also a digitized vector map may contain various types of errors such as segment breaks, overshoots, slivers, imbedded lines etc.

Map edit module supports:

  • On screen digitization of scanned maps and conversion of digitized coordinates into ground coordinates using tic marks, projection and scale
  • Clean helps to remove the digitizing errors in the vector data such as overshooting segments, hanging segments, duplicate segments etc.
  • Topology can be built for the formation of polygons and the vector layer can be rasterized into a raster layer choosing the resolution.
  • Attribute tables get created for point, segment and polygon layers.
  • Support for map projections including Polyconic, UTM, Equatorial Mercator, Lambert 2 Standard Parallel, Albers 2 Standard Parallel, Stereographic, Miller, Gnomonic, Planimetric Import of GPS Data.
  • Creation of raster maps from each layer, based on the value of any attribute in the associated database.
