India's central government is working on an integrated location-based emergency response system to improve emergency response in communities. The project has been approved by the Indian Cabinet Committee on Economic Affairs after receiving a proposal from the Ministry of Home Affairs.
Most of the LiDAR systems available today are single beam scanning systems, where you’re detecting the return from a single beam or pulse of light. The geometry for that is fairly difficult, and you’re limited by the speed of light. You can’t send out another pulse of light until you’ve gotten the return from the previous pulse. That limits the altitudes from which the sensors can be flown.
The Japan Aerospace Exploration Agency (JAXA) is working to compile images acquired by its Advanced Land Observing Satellite "DAICHI" to develop a high-resolution global digital terrain map. With a resolution of five meters in both spatial resolution and height accuracy, this new global model would greatly improve upon the elevation data that is available now.
China's National Administration of Surveying, Mapping and Geoinformation has indicated that it will offer basic geographic information at low cost or free to spur the growth of the country's geomatics industry. The policy follows a similar and growing approach for countries worldwide that have been able to document economic growth through a network of supporting industries that add value and services through use of this free data.
Crews have recently returned from mapping different ecologically sensitive areas in Kerala. The detailed field exercise was taken to verify the areas identified in the high level working group led by K. Kasturirangan. These maps are now being combined into a GIS to plot their location and extents.
