nyu aerial lidarNew York University’s Center for Urban Science and Progress (NYU CUSP) Professor Debra F. Laefer today released the world’s densest urban aerial laser scanning (LiDAR) dataset. 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.New York University’s Center for Urban Science and Progress (NYU CUSP) Professor Debra F.

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. The dataset was collected and processed as part of Professor Laefer’s European Research Council (ERC) $1.7 million research grant “Rethinking Tunneling in Urban Neighborhoods (RETURN)”1 with additional funding from Science Foundation Ireland. Using techniques developed by Professor Laefer’s research team, this dataset provides uniquely high resolution LiDAR data for a 1.5km2 study area of Dublin’s historic city center. The data covers not only the horizontal surfaces of the built environment, as seen in traditional LiDAR projects (e.g. roofs and roads), but also provides dense vertical data including exceptional building facade capture. This allows the creation of richly elaborated 3D models of the urban environment that accurately represent building geometry, curb height, vegetation, and utility lines. The work builds on a previously publicly released dataset (aerial laser scanning and imagery) and more than a decade of research. Permission is currently being sought to acquire similar data for New York City. Read More
