The purpose of this specification is to assure uniformityof treatment among mapping and charting elements, primarily DMA and itscontractors, engaged in a coordinat
3、ed production and maintenance program forthis product. Feature requirements are stated in terms of DMAsFeature/Attribute Coding Standard (FACS), to maintain consistency betweenvarious DMA production methods. The use of FACS in this specification is notintended to imply any external digital data codi

The Digital Geographic Information Exchange Standard(DIGEST) Feature Attribute Coding Catalog (FACC), not
5、FACS, is the approvedcoding standard for the exchange of digital geographic data, as well as thestandard for DMAs Vector Product Format (VPF) product line.
