Digitization of Cadastral Maps and Integration with RoR Data
Model-II
(Based on inputs from the ISRO/NRSC, involving use of High-Resolution Satellite Imagery)


1. The cadastral map for each village is available on larger scales like 1:4000 to 1:10,000. These maps depict the survey boundaries with survey numbers, cultural features like transport network, location features viz. temple, trees, abadi and natural features like drainage etc. These cadastral maps have been prepared using plane table survey and chain survey. These maps need to be brought under standard projection/coordinate system for effective linkage of the developmental plans generated in the GIS environment. The following is the general description of the scope of the work of digitization of the cadastral village maps, geo-coding and their integration with textural data (RoR):

• 
  The village cadastral maps will be traced on to tracing film/paper wherever required, scanned and grid-corrected.
  
• 
  These maps will then be vectorized and labeled, parcel-wise.
  
• 
  The parcel-wise information will then be attached uniquely to identify with the help of key identifier to obtain the details of each parcel.
  
• 
  A grid-corrected map of the original sheets has to be provided in hard copy format.
  
• 
  The sheets will be edge-matched, mosaiced, and the topology created as per the conventions specified.
  
• 
  The mosaiced digitized maps will then have to be converted to GIS format and transformed using ortho-rectified geo-coded High Resolution Image.
  
• 
  The accuracy standards should be maintained as per the pre-specified spatial framework, projection system, co-ordinate units, tolerances, feature-coding scheme, etc.
  
• 
  The deliverables have to be provided in proper format, structure, precision and metadata, as specified, so that they are ready for use with other revenue-related activities.
