Seashore Large-scale Mapping Acceleration Using Lidar Bathymetry The accuracy of coastline data in Indonesia could be much improved by making use of Lidar bathymetry technology. In this article, the authors describe how Lidar bathymetry survey techniques were applied to a section of coastline in the Sunda Strait. The determination of a sea or coastal area depends on the availability of coastline data, as it is based on the coastline reference (see Figure 1). The definition of the area of Indonesia’s sovereignty could be improved if it were based on accurate coastline data. Unfortunately, a ...

NASA has launched an 'interactive map' of Mars that lets you track the Perseverance rover as it begins its exploration of the Jezero crater on the Red Planet. Perseverance landed on Mars after a nail biting 'seven minutes of terror' on Thursday that involved plummeting through the atmosphere at 12,000 miles per hour. It was a particularly complicated landing as the area in the crater is littered with jagged rocks and obstacles, requiring thousands of lines of code to allow the rover to negotiate the complicated terrain without human input. To allow people to continue tracking the location of ...

Building research tools to improve response and resilience to flooding in Syria Format February 5, 2021 Displacement associated with disasters and the effects of climate change is one of today's most serious humanitarian and development issue.
