GIS Data Layer
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 projects.

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 together. Software used for GIS data layer work includes AutoDesk's AutoCAD Map, ESRI's ArcGIS.
