This resource provides bulk downloads of point cloud data from datasets hosted by OpenTopography. It is designed for advanced users seeking to download large amounts of data quickly and who have the bandwidth, expertise, and software necessary to manage the gigabytes of data available. We expect that users accessing bulk data have the ability to automate downloads from the command line via tools such as wget, curl, or a download manager such as DownThemAll
Each dataset directory contains all of the point cloud data for a given data collection and are typically organized into tiles (e.g., 1 km2 tiles) and provided in the lossless LASZip format for download efficiency. When possible, a README file in the directory describes the dataset organization and other important information. Metadata for all datasets can be accessed via the OpenTopography Metadata page and users should consult the collection survey report for additional information on data organization, file naming conventions, coordinate systems, etc.
By accessing data via OpenTopography you agree to acknowledge OpenTopography and the dataset source as specified in the dataset metadata and on OpenTopography's data acknowledgement page in publications, presentations, and other materials produced using these data.
