- Description:
-
- Abstract:
-
Mining feature symbols digitized from 1:24000 scale, 7.5 minute USGS topographic quadrangles as scanned by the Stephen P. Teale Data Center (July, 1998).
- Purpose:
-
To develop a statewide digital spatial dataset of accurately located mining features. Other digital datasets covering the state are limited to mining operations (or claims) but do not locate physical features resulting from mining.

-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
-
Ten percent of the quads were sampled for omission and attribute accuracy. From the sampled population, there were approximately ten percent errors on the attributes and ten percent on omission. All found errros were corrected.
- Logical_Consistency_Report:
-
Logical consistency was insured by ocular inspection. No specific systematic tests were employed.
- Completeness_Report:
-
Data is statewide in extent. Coverage varies from quadrangle to quadrangle due to revisions of the source maps.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
Positional accuracy is reliant on the accuracy of the original source maps. USGS topographic quadrangles typically state that the maps comply with national map accuracy standards. Human digitization of the mining symbols has likely added slight deviations from the original source map, though no formal method has been undertaken to quantify this additional error.

All data in the dataset is derived from the 1:24,000 7.5-minute USGS topographic quadrangles. See trimdrg1.txt for source metadata
- Process_Step:
-
- Process_Description:
-
Each DRG covering a quadrangle was occularly inspected for mining features (as markers, lines or areas). Features were digitized from the DRG's and attributes were completed concurrently. The feature layers for each quadrangle were then merged to form a statewide dataset. Several quality control inspections were undertaken to identify errors of omission, comission and positional errors. Such errors have been corrected where identified.

- Attribute_Definition:
-
Indicates whether a particular point is a duplicate representation of a given linear or areal feature. Each linear or areal feature has a point representation in each quadrangle it crosses. By selecting all features where "dupe_point" = 0, it is possible to filter out the duplicate point representations. The duplication allows a point representation of linear and areal features to be used both on a landscape and per quad basis.
