‘All types of spatial data should be integrated’

New Delhi, India: There should be an agency in India to bring all spatial data like census maps, wetland maps, geological maps, etc together. It is important to deal with emerging threats like terrorism, observed Dr. Prithvish Nag, Director, National Atlas and Thematic Mapping Organisation (NATMO), India. He acted as the chairperson of the plenary session, National Mapping Policies: Implementation, Challenges and Way Forward, during Geointelligence Asia 2011 in New Delhi, India.

Opening the session, Maj. Gen. R C Padhi, DDG Military Survey, MOGSGS, India, said information becomes geoint when it is timely, relevant and accurate. He explained reasons why maps initially were not made available for the public. He opined that emergence of GIS technologies compelled the government to release ‘National Map Policy’ in 2005. Maj. Gen. Padhi elaborated types of maps offered under National Map Policy 2005. He also explained the characteristics of Everest Series Maps of India. They were prepared at 1:50k, 1:25k and 1:250k scale. He updated that now Survey of India is preparing maps at 1:10K scale for rural areas and maps at 1:2k scale for urban areas.

Maj. Gen. Padhi informed that under the map policy 2005, IAF, NRSA and Kolkata-based Air Svy Co were assigned to do aerial survey mapping for defence purposes. He expressed concern over the fact that India still does not have a single aerial survey company while a small country like New Zealand has several. He observed that such services are important in the country in the backdrop of exponential technological advancements around the world in terms of UAVs and drones.

Wg Cdr (Retd) A K Jha, General Manager, Leica Geosystems – Geospatial Imaging, India, observed that there should be a central agency to take care of all geospatial data collected by different departments like Survey of India, Geological Survey of India, Archaeological Survey of India and Forest Department.
