DCW
- Digital Chart of the World
The Digital Chart of the World (DCW) is an Environmental Systems
Research Institute, Inc. (ESRI) product originally developed
for the US Defense Mapping Agency (DMA) using DMA data. The
DCW 1993 version at 1:1,000,000 scale was used. The DMA data
sources are aeronautical charts, which emphasize landmarks important
from flying altitudes. This explains why there is a separate
aeronautical theme with all conceivable airports, why on some
themes small islands and lakes are simply unnamed points. ESRI,
in compiling the DCW, also eliminated some detail and made some
assumptions for handling tiny polygons and edgematching. Also,
note that the completeness of the thematic categories present
in each layer will vary. |
