Description:

Abstract:: These maps are a digital representation of the individual tree species range maps of the "Atlas of the United States Trees" by Elbert L. Little, Jr. The atlas shows the natural distribution or range of the native tree species of North America. These coverages represent 3 volumes of the atlas.
Purpose:: To create a digital representation of the vegetation range maps published in "Atlas of United States Trees" by Elbert L. Little, Jr.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The single user-defined attribute ("code") has an enumerated domain (values of 0 or 1 only), so numerical measures of accuracy are not applicable. The data sets were checked for attribute accuracy by visually comparing color-coded plots of each dataset with the source maps.

Logical_Consistency_Report:

In some instances, data for the United States portions of the maps were derived from source maps at 1:10,000,000 scale and the portions outside the United States were derived from sources at approximately 1:27,000, 000 scale. The coverages were checked for node, intersection, and duplication errors and corrected when necessary. All polygons were snapped closed at nodes.

Completeness_Report:

All polygons on the printed source maps are represented in the digital coverages.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: At least 90% of the points tested on hard copy printout are within 1/50 inch (0.5mm) of the source data.

Process_Step:

Process_Description:: The coverage was created by scanning the map of each species range from the book, registering to a county coverage at 1:2,000,000 scale using the ARC/INFO REGISTER command, and rectifying.
Process_Date: 1999

Process_Step:

Process_Description:: Digitized ploygon boundaries on screen using scanned and registered images as reference.
Process_Date: 1999

Process_Step:

Process_Description:: Added CODE attributes to coverages; assigned attribute of 1 to polygons representing presence of plant species and 0 to all other polygons.
