Researchers created 3-D maps of prime spider habitats in a German national park using LiDAR, a remote-sensing system mounted on helicopters. The system uses lasers to characterize broad swaths of land in relatively little time, as opposed to doing surveys on foot that could take months.
Thanks to high-resolution images, Duke University and Meredith College geoscientists were able to add 657 new barrier islands to the total count, adding 30 percent more to the known list. There are now 2,149 discovered islands in total.
Among the tools used: Google Earth and actually visitation!
Nearly four months after the amended Coastal Regulation Zone (CRZ) notification was introduced by the Union Government, the Brihanmumbai Municipal Corporation (BMC) is set to map the city’s shoreline and water bodies with the help of satellite imaging.
The BMC will soon initiate the process of mapping ecologically sensitive spots including, mangroves, beaches, koliwadas, etc and prepare new maps for these areas which are protected under the CRZ notification.
