Individual map separates were scanned and vectorized to Alaska Division of Geological & Geophysical Surveys (DGGS) specifications in a program called Raster to Vector Map Conversion (R2V) by Able Software. The magnitude of error associated with vectorization of the raster images is very small or non-existent. Essentially, during auto-vectorization, lines on the scanned image are traced by the program, producing vector lines. Able Software reports that no spatial error occurs during automated vectorization.
Individual map separates were scanned and vectorized to Alaska Division of Geological & Geophysical Surveys (DGGS) specifications. The magnitude of error associated with the step is unknown but it assumed to be very small or non-existent relative to possible errors in the associated geologic dataset.

This dataset includes geospatial data that contain information about the topography and hydrology of the Chandler Lake C-4 and B-4 1:63,360 quadrangle maps as illustrated by the U.S. Geological Survey.
Topology is present on appropriate line and polygon datasets.
