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 Kentucky holds:
| Measurement type | Geometry | Measurements | Share |
|---|---|---|---|
| Joint | Planar — strike and dip | 2,048 | 68% |
| Bedding | Planar — strike and dip | 837 | 28% |
| Other | Planar — strike and dip | 54 | 2% |
| Vein / dike | Planar — strike and dip | 46 | 2% |
| Fault plane | Planar — strike and dip | 8 | <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 |
|---|---|---|
| Kentucky Geol. Survey | 2,048 | 68% |
| NPS GRI parks | 899 | 30% |
| USGS data releases · MRDS | 46 | 2% |
