USGS 3DEP LiDAR Point Clouds
This AWS Public Dataset project is about processing the USGS 3DEP LiDAR point cloud data into a form that is cloud-friendly, streamable, lossless, and convenient.
The main landing page on AWS for the project is at https://registry.opendata.aws/usgs-lidar/
Public 3DEP LiDAR data is available in two forms on AWS:
- A Requester Pays
s3://usgs-lidarcontaining many of the USGS resources available as full-density LASzip tiles
- A public access bucket at
s3://usgs-lidar-publiccontaining EPT resources mirroring many (but not all) of the resources in #1.
A description of the EPT format, which is a hierarchical format arranged by progressive level-of-detail, is contained at https://entwine.io/entwine-point-tile.html. EPT was chosen as the service mechanism for this data due to its scalability potential to trillions of points, flexibility, and its ease of use via open source infrastructure like PDAL, LASzip, Potree, and Plasio.js.
Data processing with Entwine was performed on AWS EC2
instances using S3 for output storage.
Currently, there are more than 10 trillion LiDAR points available in over 950
The EPT data is accessible via EPSG:3857 for ease of web usage - with PDAL the data can be reprojected on the fly with the reprojection filter which can be used in combination with other processing pipeline stages.
Thank you to the multiple organizations that have supported the development of the USGS 3DEP LiDAR dataset.
The US Army Corps of Engineers Remote Sensing / GIS Center of Expertise at CRREL sponsored the processing and development of the AWS 3DEP Public Dataset in multiple ways. First, it sponsored the development and continuing support of PDAL and Entwine open source software libraries, which were used to process and manage the data. Second, it supported the processing and management of the 3DEP data to an Entwine Point Tiles public dataset.
The AWS Public Datasets Team supported the effort by providing processing and storage grants for the development of the EPT data and ongoing support by making access to that data publicly available.
