Cadastral Mapping, AutoCAD Vectorization & Spatial Database for an Entire Himalayan State
Project Overview
Mapsets was entrusted with the prestigious task of digitizing the entire cadastral map database of Sikkim, making it one of India’s most ambitious Land Information System (LIS) projects. The initiative aimed to create a vectorized, query-enabled, spatially accurate map set for each plot of land in the state—covering towns, rural areas, and forest borders.
All data was digitized in AutoCAD, overlaid with GPS-referenced field inputs, and structured into an intelligent LIS system, ensuring land transparency and modernized governance.
Key Components & Deliverables
- Full digitization of cadastral maps at village and parcel levels
- AutoCAD vectorization of all property boundaries
- Georeferencing using DGPS & satellite imagery
- Creation of spatial layers for ownership, land use, encroachments
- Development of a land dispute resolution-ready platform
- Training of local teams on GIS tools and LIS maintenance
Technologies & Methodologies Used
- AutoCAD for high-precision map vectorization
- Ground truthing with DGPS and Total Stations
- Overlay of cadastral boundaries on satellite imagery
- Integration into GIS-based Land Information System
- Layered data architecture for land type, title, and usage
- Customized modules for land transfer & title management
Enabling Transparent Land Governance in Sikkim
This project enabled the Government of Sikkim to transition to a fully digital land records management system, minimizing disputes, improving tax collection, and enabling better planning decisions. The project received formal technical approval from the Ministry of Rural Development and is considered a model for other hilly and land-sensitive states in India.
