Consolidated Standardized Survey-Grade Checkpoints 3DEP 2010 to 2017 [USGS]
--
sciencebase.gov/catalog/item/6
--
“One 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...”

[this post should not be considered an endorsement of any organisation, but is shared for learning purposes]
“LiDAR or Light Detection and Ranging is an active remote sensing system that can be used to measure vegetation height across wide areas.
This [tutorial] page… introduce[s the] fundamental LiDAR (or lidar) concepts including:
• What LiDAR data are.
• The key attributes of LiDAR data.
• How LiDAR data are used to measure trees...”

USGS 3DEP LiDAR Collection @ Microsoft
--
planetarycomputer.microsoft.co <-- Microsoft data / use case portal
--
“To 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…”

What Is A Digital Elevation Model (DEM)?- A Practical Guide
--
equatorstudios.com/what-is-a-d <-- shared tutorial
--
“A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”
