Tamil Nadu plans satellite imaging to check illegal mining
Posted on: 24/Oct/2012 10:21:50 AM
Tamil Nadu is set to go hi-tech to curb encroachments with its mining tenement registry through Global Information System (GIS) and satellite images.
This will involve creation of a comprehensive database of mining tenements in mineral bearing areas in various districts. The registry will also provide satellite images of cities and villages with survey numbers along with details of mining leases.
The registry will cover nine districts — Madurai, Coimbatore, Salem, Tirunelveli, Krishnagiri, Trichy, Ariyalur, Virudhunagar and Villupuram.
The system will display the outline of every tenement and geographically place it on the globe along with its features such as names of the lessees, extent of the areas and mineral date of grant.
Digitization of cadastral maps (showing boundaries and ownership of land) is the first step in the creation of a GIS-enabled mining tenement registry. The mineral atlas will show mineral resources of the state as well.
The software will continuously compare the original measurement of the land with the satellite pictures of lease area size.
In Tamil Nadu, the major minerals mined and used by industries include limestone, quartz and feldspar, garnet, magnesite, silica, bauxite, vermiculite, graphite heavy mineral sand and iron ore. The director of geology and mining is empowered to grant mining lease for major minerals on patta lands.
