Interpreted photos were quality checked by two photointerpreters for attribute classification. Field verification was performed to assure signatures. The mylar-based maps were checked by cartographic personnel for line and labelwork. The attribute accuracy for the digital data is tested by manually comparing hard copy plots with the source materials.
The horizontal positional accuracy is tested by visual comparison of hard copy check plots to the source materials and verifying the location of the data on-screen relative to other data layers in the same geographic area.
Not applicable
For cartographic process, accordance with nationally accepted mapping standards and conventions are followed.
Procedures and techniques used in the mapping process were derived from, and are in accordance with, nationally accepted standards and conventions for map accuracy and habitat mapping. GIS software is used to create and maintain topological relationships between features. There are no duplicate features, but coincident lines are maintained between data layers where appropriate. Polygonal features begin and end at the same point, contain no overshoots or undershoots, and contain a single label. Linear features, if present, are continous, i.e., dangling arcs are removed if they are not required.
Are there legal restrictions on access or use of the data?
