- Abstract
- This ARC/INFO polygon coverage contains the third Level administrative boundaries 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 third Level administrative boundaries 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 administrative boundaries for the Central African Republic were extracted from the MRPDA database using the ARC/INFO command RESELECT. These country specific sub-national boundaries were then integrated into the DCW master country database using the ARC/INFO command UPDATE. The country specific data set, containing all of the sub-national hierarchy, was extracted from the DCW master data set using the ARC/INFO command RESELECT and the third Level administrative units were extracted from the country specific data set using the ARC/INFO command DISSOLVE. A master data set, based on the Digital Chart of the World (DCW) PONET layer, was created. Burkina Faso, Mali, Ethiopia, and Eritrea are included in the master data set, however, these countries have international boundaries that have been revised. The changes to Burkina Faso are: The Digital Chart of the World (DCW) International boundary was used for the International boundary for Burkina Faso with the only revisions being those listed below. From : -2 degrees; 55 minutes; 8 seconds Longitude and : 13 degrees;37 minutes; 37 seconds Latitude To : -0 degrees; 57 minutes; 41 seconds Longitude and : 14 degrees; 52 minutes; 14 seconds Latitude AND... From : 0 degrees; 3 minutes; 33 seconds Longitude and : 14 degrees; 58 minutes; 15 seconds Latitude To : 0 degrees; 13 minutes; 55 seconds Longitude and : 14 degrees; 58 minutes; 15 seconds Latitude These changes are defined by FEWS/ARD Washington, DC, USA. The changes to Mali are: The Digital Chart of the World (DCW) International boundary was used for the International boundary for Mali with the only revisions being those listed below. From : -2 degrees; 55 minutes; 8 seconds Longitude and : 13 degrees;37 minutes; 37 seconds Latitude To : -0 degrees; 57 minutes; 41 seconds Longitude and : 14 degrees; 52 minutes; 14 seconds Latitude AND... From : 0 degrees; 3 minutes; 33 seconds Longitude and : 14 degrees; 58 minutes; 15 seconds Latitude To : 0 degrees; 13 minutes; 55 seconds Longitude and : 14 degrees; 58 minutes; 15 seconds Latitude These changes are defined by FEWS/ARD Washington, DC, USA. The changes to Ethiopia are: The Digital Chart of the World (DCW) International boundary was used for the International boundary for Ethiopia with the only revisions being those listed below. From : 36 degrees; 34 minutes; 5 seconds Longitude and : 14 degrees; 14 minutes; 25 seconds Latitude To : 42 degrees; 25 minutes; 22 seconds Longitude and : 12 degrees; 26 minutes; 53 seconds Latitude These changes are defined by FEWS/ARD Washington, DC, USA. The changes to Eritrea are: The Digital Chart of the World (DCW) International boundary was used for the International boundary of Eritrea with the only revisions being those listed below: From : 36 degrees; 34 minutes; 5 seconds Longitude and : 14 degrees; 14 minutes; 25 seconds Latitude To : 42 degrees; 25 minutes; 22 seconds Longitude and : 12 degrees; 26 minutes; 53 seconds Latitude These changes are defined by FEWS/ARD Washington, DC, USA. The international boundary for the Central African Republic 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.

- Currentness Reference
- The "MRPDA" was published in 1994. Many sources were used to compile the data. 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 in April of 1996 by the EROS Data Center (EDC).
