Iron ore mining major NMDC has set up a remote sensing and GIS lab to use satellite imagery for exploration.
N. Baijendra Kumar, CMD, NMDC, inaugurated the “Remote Sensing & GIS Lab” at the company’s premises in the presence of Santanu Choudhury, Distinguished Scientist and Director, National Remote Sensing Centre (ISRO), Department of Space.
NMDC and NRSC (ISRO) had joined hands through an MoU to promote space applications in exploration and other mining activities for "satellite-based geological mapping and multi-disciplinary exploration of iron, diamond and other mineral deposits.” The move is a step towards “Digital India” as Space Technology provides real-time data for generation of digital maps.
NMDC is the first CPSE in the Ministry of Steel which has signed an MoU with ISRO for use of space technology in mineral exploration and mining and this has been highlighted as a special achievement of the Union Ministry of Steel.
Several innovative methods were used by NMDC-ISRO for targeting diamond and iron bearing areas. Gravity and magnetic data of ElGEN6C4 (NASA) satellite was also used for identifying potential corridor for diamondiferous rocks in the Central Indian Diamond Province.
A few potential iron ore blocks have also been identified in Madhya Pradesh using Cartosat-2 and Aster Data.
NRSC and NMDC have developed a mobile app to collect field data with location and field photo and catalogue to collect geological information and for viewing in “Bhuvan Portal”. This app is being used by NMDC in its Sidhi-Singrauli Iron ore Block and Chattarpur & Damoh Diamond Blocks for field data collection and has proved to be very useful. NMDC is using MOBILE GIS studies using above APP and "Bhuvan Platform" in all its exploration programmes.
The remote sensing and GIS Lab has two licences each of "ERDAS" and "ARC-GIS" software along with high end workstations.
NMDC will use the facility for exploration and would fully go "Digital" in the areas of exploration.
