    β€œOne of the key aspects of 3DEP data is that data is verified by a collection of certified survey-grade GNSS checkpoints spread throughout each project. These points have always been available but were difficult to find and not standardized. [The USGS] have collated and standardized almost 42,000 of these checkpoints and are making them available for other uses. These points here in this first phase span from 2010-2017, but [the USGS] are in the process of making these available for all [their] projects, and hope to enable them in different ways in the future...”

  6. USGS 3DEP LiDAR Collection @ Microsoft

    --
    β€œTo respond to growing needs for high-quality elevation data, the goal of 3DEP is to complete acquisition of nationwide lidar (IfSAR in AK) to provide the first-ever national baseline of consistent high-resolution topographic elevation data – both bare earth and 3D point clouds. This dataset provides the raw 3D point clouds in the Cloud Optimized Point Cloud format, and various derived products as Cloud Optimized GeoTIFFs…”

    [sad that Mastodon kills the resolution in the image, such stunning hydromorphology can be seen in the data]
