Ambala district of Haryana has taken a lead in modernisation of land records in the state by digitising cadastral maps for better land administration.

A cadastral map shows the boundaries of land, usually with areas of individual trac digitising cadastral maps for better land administrationts, for purposes of describing and recording ownership for the purpose of taxation.

The geo-referenced 0.5 meter resolution world view (WV) satellite data has been acquired by Haryana space applications centre (HARSAC), Hisar, for the entire state.

It will be overlaid on the digitised cadastral maps used to correct inaccuracies in the data, a spokesman of Haryana revenue department said on Saturday.

This overlaying would also create the latest database about the land use, forestry, geo-morphology, soil, water prospects and land degradation for each acre of land in the state.

The project has been accomplished with technical support from HARSAC and national informatics centre (NIC), Haryana, he said adding that revenue records of Ambala district are being digitised and updated using the high resolution satellite imageries.

The updated maps would be geo-referenced using the benchmark ground control points (GCP) which have been fixed in the entire state using advanced technology of differential global positioning system (DGPS).
