Technical.ly Brooklyn features Professor Debra Laefer’s research on the world’s densest urban aerial lidar data set.
New York University has made available the densest public LiDAR data set ever collected, via its Center for Urban Science and Progress. The laser scanned data, collected using aerial LiDAR instruments, is about 30 times as dense as a typical data set at a resolution of around 300 points per square meter, and covers a 1.5km square region of Dublin’s city center.
The data was collected by Professor Debra F. Laefer and her research team, and includes both a top-down view of the roofs and distribution of buildings, as well as info about their vertical surfaces, making it possible to build 3D models of the urban landscape with detail around building measurements, tress, power lines and poles and even curb height, CUSP says.
