All attributes have been checked against original, paper Preliminary Landslide Maps. Not all landslides have been field-verified.
The Wyoming State Geological Survey Prelminary Landslide Maps were developed from the United States Geological Survey (USGS) 1:24,000-scale quadrangle maps. According to the USGS National Mapping Accuracy Standards, these quadrangle maps have an inherited error of +/- 40 feet. Therefore, accuracy for this dataset is approximately +/- 40 feet. This estimation has not been formally tested. The estimation is based on the National Mapping Accuracy Standars, taking into account the source scale of the aerial photographs, limitations associated with interpreting and transcribing polygons by hand, and scanning hand-drawn polygons on USGS 1:24,000-scale base maps. This coverage was registered using four tics, one at each corner, and an RMS error (input, output) = (0.003, 2.044).
All polygons are appropriately labeled.
The polygon topology has been checked and verified. All polygons are closed. Each polygon has one label. All dangles and slivers were removed.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None.
- Use_Constraints:
- These Preliminary Landslide Maps are NOT to be used at a scale larger than 1:24,000. Not all landslides may have been mapped. Not all landslides have been field checked.
