What kinds of measurement

The Atlas separates planar structures, recorded as a strike and dip, from linear ones, recorded as a trend and plunge. This is what Indiana holds:

Measurement typeGeometryMeasurementsShare
Other Planar — strike and dip 4892%
Vein / dike Planar — strike and dip 48%

Where the data comes from

Each source is a survey, agency or program whose published mapping was harvested and reconciled into one schema. Rows are published only where the source's terms permit redistribution.
