Our services include digitization of geo-spatial features, data
extraction of attributes from raster images or paper maps, data
entry into database and linking of database to drawing for GIS
Our key strength in the field is our ability to convert large volumes of paper maps and drawings to digital format with quick turn-around times. The sources could be a combination of topographic maps, CAD drawings, satellite imagery, aerial photographs or observations from field surveys.
Maps are digitized manually using CAD overlay method where
raster image of the map is used as a backdrop. Both the drawing
and the data are checked for correctness before linking them
Software used for GIS data layer work includes AutoDesk's
AutoCAD Map, ESRI's ArcGIS.
