Cadastral Mapping
A cadastral map refers to a map that shows the boundaries and ownership of land within a specified area. This can include details like district names, parcel IDs, structures, and street names. It facilitates land ownership transfer, records land ownership, and assists in valuation and taxation of land.
Cadastral mapping has four main purposes:
- Provides a record of official/private land surveys.
- Facilitates administration/transfer of land ownership.
- Records land ownership.
- Assists in land valuation & taxation.
Digitization
Digitization is the process of converting analog maps, imageries, or aerial photos into digital format—often through manual or “heads-up” digitization. This is a crucial step in GIS data capture, forming the backbone of any GIS industry project.
Spatial data often starts as paper maps or aerial images. Proper reproduction of analog data into digital form remains a key bottleneck. Success in GIS mapping hinges on the accurate capture of this analog data into a workable digital form.
