Summary

Vertical accuracy of elevation data in coastal environments is critical because small variations in elevation can affect an area’s exposure to waves, tides, and storm-related flooding. Elevation data contractors typically quantify the vertical accuracy of digital elevation models (DEMs) developed using light detection and ranging data acquisition on a per-project basis to gauge whether the datasets meet quality and accuracy standards. To better understand the vertical accuracy of DEMs along the Gulf of Mexico and Atlantic coast, we collated over 5200 contractor points for this region that were collected for per-project-level analyses produced for assessing DEMs acquired for the U.S. Geological Survey’s 3D Elevation Program. Upon pooling [...]

Purpose

Checkpoint data were initially collected by contractors for the internal assessment of DEMs collected for the 3D Elevation Program (3DEP). These collated checkpoints can be used by researchers and natural resource managers to provide spatially explicit information on the accuracy of DEMs along with providing additional information regarding how accuracy is related to USGS Quality Level and land cover type.
