The suitability of Photogrammetry or Lidar point clouds depend on the particular application. Photogrammetric point clouds have an RGB value for each point, resulting in a colourised point cloud. On the other hand, when it comes to accuracy, Lidar is hard to beat. Since all the projects do not require the same accuracy, it is always good to do some research before you decide which method works best for you.

Only a few weeks after it was launched, the Copernicus Sentinel-3B satellite has delivered its first images of Earth. Sentinel-3B is the seventh Sentinel satellite launched for Copernicus. Each mission carries different state-of-the-art technology to deliver a stream of complementary imagery and data to monitor the environment.
The satellite captured the images that show the transition between day and night over the Weddell Sea in Antarctica. It also captured swirls of sea ice off Greenland on the same day. Another in this first set of images offers a rare cloud-free view of northern Europe.
It shows how the satellite is set to play it’s role in providing a stream of high – quality environmental data to improve lives, boost the economy and protect our world.

Recently, NMDC inaugurated the “Remote Sensing & GIS Lab” at Hyderabad on 02 May 2018. NMDC and NRSC (ISRO), Department of Space, Government of India joined hands through a MoU to Promote Space Applications in exploration and other mining activities for “Satellite Based Geological Mapping and Multidisciplinary Exploration of Iron, Diamond and other mineral deposits”. It is a major step forward towards “Digital India” as Space Technology provides real – time data for generation of digital maps.
The Remote Sensing and GIS Lab has two Licences, “ERDAS” and “ARC-GIS” software along with high end “Workstations”. NMDC will utilize the facility for exploration and would fully go “DIGITAL” in the areas of exploration.

DEHRADUN: Ever wondered how pilgrims negotiated their way to the Chardhams – the famed religious circuit comprising four Hindu shrines – through the treacherous Himalayan terrain when there were no roads? The historic trails are now being mapped by the Indian National Trust for Art and Cultural Heritage (INTACH), a non-profit organisation that works for conservation of cultural heritage.
At a recent roundtable event organised by Esri UK, representatives of the North Wales police force, Wessex Water and the Environment Agency talked about how they were using geographic information systems (GIS) in their work to provide Operational Intelligence (OI).
