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 Utah holds:
| Measurement type | Geometry | Measurements | Share |
|---|---|---|---|
| Bedding | Planar — strike and dip | 4,902 | 51% |
| Vein / dike | Planar — strike and dip | 2,255 | 23% |
| Joint | Planar — strike and dip | 1,947 | 20% |
| Other | Planar — strike and dip | 361 | 4% |
| Lineation (mineral, stretching) | Linear — trend and plunge | 80 | <1% |
| Foliation | Planar — strike and dip | 62 | <1% |
| Fold hinge / axis | Linear — trend and plunge | 39 | <1% |
| Fault plane | Planar — strike and dip | 22 | <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 |
|---|---|---|
| NPS GRI parks | 5,785 | 60% |
| USGS data releases · MRDS | 2,333 | 24% |
| USGS NGMDB GeMS | 1,217 | 13% |
| NGMDB legacy quads | 333 | 3% |

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 Utah.
