Lesson 10.1 Spatial Metadata for 3DEP

This National Map training is an overview of the Work Unit Extent Spatial Metadata (or WESM) for USGS 3D Elevation Program data. The WESM contains information about lidar projects, including lidar quality level, data acquisition dates, and links to project-level metadata. In this video, you’ll learn about WESM attributes, the online data dictionary, and how to query the WESM to find lidar data.
