Recently professor Debra F. Laefer, with NYU’s Center for Urban Science and Progress–released what the center is calling the world’s densest urban aerial lidar data set. Here’s how it was described in the original press release:
At over 300 points per square meter, this is more than 30 times denser than typical LiDAR data and is an order of magnitude denser than any other aerial LiDAR dataset. The dataset also includes the first ever urban scan with the fullwave form version of the data, as well as affiliated imagery and video. The unprecedented comprehensiveness of this multi-layered dataset enables new opportunities in exploration and modeling. It also sets a new standard for what can be collected and used by cities around the world. The data and affiliated information is now publicly available through New York University’s Spatial Data Repository (SDR) here for both personal and commercial use.
To find out more, SPAR3D caught up with Dr. Laefer, who explained the technology and the techniques used for capture, as well as the issues facing the team as they attempt to make the data useable to everyone who needs it.Read More
