Barba Phase Occupation Map

BARBA.DXF is a map of all Barba phase occupied areas (all collection lots with identifiable Barba sherds). Collection lot numbers are not included--only the collection lot boundaries indicated as closed AutoCAD polylines. The maps are georeferenced to topographic maps in coordinate systems projected from latitude and longitude (Lambert North Projection) using Clarke 1866 ellipsoid and Ocotepeque Datum (Fundamental de Ocotepeque) of 1935. Units are expressed in meters. The layers and their contents are:

• STUDY_AREA (white/black) -- The boundary of the survey area
• BARBA (blue) -- Polylines defining the collection lots containing Barba ceramics. The elevations (z-values) of the closed polylines represent the Barba sherd density of each lot per square meter.

The same information is also provided in ArcGIS .SHP format in the file BARBA.ZIP (12 KB), which uses the UTM Zone 16N (units are meters) coordinate system based on the WGS84 datum.
