Creation of cluster polygons Kutch Nav Nirman Abhiyan
Georeference of Cadastral Map • Georeference is the process through which a digital map is associated with real geographical coordinates. • With the help of Download image there is 10 to 20 point is selected for georeference of the cadastral map Kutch Nav Nirman Abhiyan
Personal Geodatabase • Purpose • All files relating to a project can be stored into the geodatabase file, making it easier to organize and transfer data if necessary. • Both the geographic files and the tabular data can reside within a single geodatabase. • The three layer is created in personal geodatabase • Road • Drainage and • Contour Kutch Nav Nirman Abhiyan
Digitization of Toposheet • Digitization of Toposheet was done with manual hand tracing of the lines on the computer screen, using the scanned raster image in the backdrop. Kutch Nav Nirman Abhiyan
