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 Wyoming holds:
| Measurement type | Geometry | Measurements | Share |
|---|---|---|---|
| Foliation | Planar — strike and dip | 9,725 | 54% |
| Bedding | Planar — strike and dip | 5,870 | 33% |
| Lineation (mineral, stretching) | Linear — trend and plunge | 992 | 6% |
| Other | Planar — strike and dip | 819 | 5% |
| Fold hinge / axis | Linear — trend and plunge | 205 | 1% |
| Vein / dike | Planar — strike and dip | 162 | <1% |
| Joint | Planar — strike and dip | 122 | <1% |
| Fault plane | Planar — strike and dip | 9 | <1% |
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.
| Source | Measurements | Share |

| USGS NGMDB GeMS | 7,121 | 40% |
| Wyoming WSGS | 6,816 | 38% |
| NPS GRI parks | 3,455 | 19% |
| NGMDB legacy quads | 428 | 2% |

Most-measured map units
Where a source recorded the geologic unit a measurement was taken on, the Atlas keeps it. These are the units carrying the most measurements in Wyoming.
