USGS data releases · MRDS

47,492 structural measurements in the Atlas come from USGS data releases · MRDS, harvested across 15,174 published maps and data releases and reconciled into the Atlas schema.

Show only this source on the map

0% of this source's records state their own azimuth convention in the published data. Where a convention is not stated the Atlas infers it from the source's documented practice and records that it did so — which is why every row keeps a link back to the map it came from, and why a measurement that matters should be checked against that map.
