Structural Measurement Atlas
Atlas / Sources / Wisconsin WGNHS

Wisconsin WGNHS

2,871 structural measurements in the Atlas come from Wisconsin WGNHS, harvested across 18 published maps and data releases and reconciled into the Atlas schema.

Show only this source on the map

72% 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.
