AWMC Accuracy Assessments in Pleiades
AWMC’s partners at the Pleiades Project have created a range of accuracy assessments related to geographic content derived from the Barrington Atlas of the Greek and Roman World. These accuracy assessments are tailored to the scale and project of the BAtlas and will be of great use to AWMC and its database editing efforts, particularly with respect to physical geography derived from the BAtlas (coastline, rivers, islands, mountains, etc.). The ratings relate to the positional accuracy of data; positional accuracy in GIS terms is a quantifiable value and represents either the positional difference between two geospatial layers of information or between the geospatial layer itself and reality.
