LiDAR Mapping: The Complete Guide to LiDAR Surveys and Land Analysis

LiDAR mapping collects millions of laser range measurements from aircraft or drones and processes them into a bare-earth terrain model that removes vegetation and structures.

A 1-meter LiDAR land survey resolves cache pits, wagon ruts, mine shafts, foundations, and historic trails that satellite imagery cannot see, and USGS 3DEP publishes this coverage for most of the United States for free.

PinPoint Treasure runs an automated LiDAR pipeline against 3DEP at 1-meter posting with a Local Relief Model and returns coordinate-tagged candidate features grounded in the underlying raster values.
