The broad methodology adopted for georeferncing of urban cadastral maps, its updating using high-resolution satellite data and deriving up-to-date spatial information from it is described below in brief.
Computerization of cadastral or mouza Map sheets
- Making available the village/mouza maps
- Indexing, Coding & Scanning
- Tiling map using GRID
- Digitisation of maps
- Attribute data attachment
- Hard copy output generation
- Hard copy evaluation by LRD
- Database Generation in GIS environment
- Softcopy validation by LRD in GIS environment
- Final hard copy generation
- Final hard copy validation
|
Satellite data preparation
- Acquisition of satellite data
- GRIDBASE generation
- MAPGRID generation
- Geo-referencing of LISS Image
- Registration of Quickbird data
- Merged product generation
|
Geo-Referencing of cadastral maps
- Acquisition of Ground Control Point (GCP)
- Geo-referencing of cadastral map
- Validation of geo-referenced output
- Edge-Matching of neighboring village maps
- Mosaic generation at mouza Level
|
Urban Information extraction
- Interpretation of satellite data
- LU code inputting on cadastral boundary
- Onscreen digitization of new boundary/parcels
- LU code inputting on new polygons (updated cadastral plots)
- Ground truth collection (plot level)
- Attribute data collection
- Attribute data/Secondary/Legacy data linking
- GIS database generation

The LIS/UIS (Urban Information System) generated from the geo-referenced cadastral base datasets, has large potential to address issues related to Municipal Information System development, Monitoring developmental activities at parcel level, Land value assessment, Content updation of Cadastral maps, Property tax assessment, Revenue collection, Demarcation of conservation zones, Utility and facility provisions, Solid waste management, Infrastructure networking, Management of Telecommunication \water supply \Power distribution networks and for enforcement and implementation of comprehensive development plans.
The Cadastral Level digital GIS database developed by using Cadastral data and QuickBird data for Bhubaneswar-Cuttack Urban Complex (BCUC) Region is used for development of Comprehensive Development Plan of BCUC region
