Data sources used in this process:
The sources used for digitizing strata boundaries are 1:100,000 scale Digital Raster Graphics
There are no known gaps in the data. There are several small islands belonging to BayField County that are omitted for generalization purposes. This data set includes the area in square miles and number of acres for each strata. The area sampling frame strata boundaries may not be coincident with strata boundaries of adjacent states.
No checks for topological consistency were performed on this data set. Visual checks were performed on the attribute data.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
