Updation and Metrology of Cadastre and Village Boundry Using High-Resolution Sattellite Data

Abstract

A Cadastre or Land parcel is extent of land and Shown in the Government Records Associated with a Set of Ownership Rights Officially Recognized as Property. The Scale of the Village Maps Varies in Different States but the most Common being 1: 4000. The Cadastre Boundary is Quite Old Which calls for fresh mapping / Updating. The availability of high-resolution data from Satellite-based platform has opened up new Possibilities for Cadastre Mapping and updating with unique opportunity of natural resources appraisal form multi-spectral information. The Village boundaries have also been modified using corrected Satellite Data, which Follows Certain topographic Features Clearly Visible on Image. The Features generally Considered for modification of the Village boundary are Road, Steam Boundaries and Field Boundaries. IKONOS Multi Spectral Image after rectification Using GCPs derived from DGPS Survey was Used to Extract land Parcels for Updation. RMS Error at GCPs was 0.57 m and 0.70m and at checkpoints, it was 1.57 m and 1.62 m in easing and Northing respectively. The Validation of the Extracted Field Boundaries were Carried out by Comparing the area measured using total Station Survey and those from Field Measurement Book (FMB).
