Attribute Accuracy:
Attribute Accuracy Report:
All attributes were compared with original maps by the person doing the attributing of the arcs and a person not involved in the attributing. Corrections were made until less than 5 errors were found after spotchecking 100 attributes at various locations on the map.
Logical Consistency Report: N/A
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
100 arcs were compared at various locations on the map by overlaying plotted arcs with the original mylar. If daylight was visible between the plotted and actual arcs on more than 5 out of 100, the arcs were redigitized until no more errors were found by 2 different people. Do not use with scales greater than the original data.
