- Abstract
- This ARC/INFO polygon coverage contains the first Level (International) boundary at a 1:1000000 scale. The coverage is part of the Famine Early Warning System (FEWS) / Associates in Rural Development (ARD) African series. The Central African Republic is associated with the Central region in Africa.
- Purpose
- This data set is to be used in conjunction with other layers of Central African Republic data. The data are intended to show the spatial distribution of the administrative (International) boundary for the Central African Republic. The data are to be used in modeling, targeting and demonstration projects. The data are also used in natural resource management, inventory, change analysis, policy making, environmental awareness and land use planning.
- Supplemental Information
- Procedures_Used: The international boundary for this country was extracted from an ARC/INFO LIBRARY created from the ARC/INFO version of the Digital Chart of the World (DCW) using the ARC/INFO tool LIBRARIAN. Revisions: During ARC/INFO coverage development modifications were made to the digital files to generate a database with a common scale, uniform Level of resolution, consistent coding scheme, and comparable (standardized) measurement data. Reviews_Applied_to_Data: Peer review, 03/96, FEWS/ARD Washington, D.C. Digital line work and attribute data checked for discrepancies and approved for release to FEWS in-country and regional field representatives.

- Temporal Extent
- Currentness Reference
- The DCW database was originally published in 1992. Data currency varies from place to place depending on the currency of the Operational Navigation Charts (ONC). Chart currency ranged from the mid 1960s to the early 1990s. Compilation dates for every ONC chart are included in the database. The additional attributes were added by EDC in April of 1996.

- Logical Consistency Report
- Polygon topology present.
- Completeness Report
- All data were found to be topologically correct. No duplicate features are present. All polygons are closed, and all lines intersect where intended. No undershoots or overshoots are present. To the best knowledge of USAID/FEWS and EDC the data compiled in this data set meets the codes and/or procedures established for completeness and consistency.
- Horizontal Positional Accuracy Report
- The absolute horizontal accuracy of the DCW for all features derived from Operational Navigation Charts (ONC) is 2040 meters (6700 feet) rounded to the nearest 5 meters at 90% Circular Error (CE), World Geodetic System (WGS84). The absolute horizontal accuracy of the DCW for all features derived from Jet Navigation Charts (JNC) is 4270 meters (14006 feet) at 90% Circular Error.
