What is the EDCS...
The Environmental Data Coding Specification (EDCS) provides mechanisms to
unambiguously specify objects used to model environmental concepts. The EDCS
supports the encoding and communication of qualitative and quantitative
information associated with physical environments, both real and virtual. The
EDCS can be used in conjunction with any data model, data structure, or
database to unambiguously define the type or characteristics of environmental
objects. The EDCS contains the following nine dictionaries of environmental
specify the type of environmental objects
specify the state of environmental objects,
attribute value characteristics:
specify information concerning the values of attributes,
specify the allowable values for the state of an enumerated attribute,
specify quantitative measures of the state of some environmental objects,
allow a wide range of numerical values to be stated,
unit equivalence classes:
specify sets of units that are mutually comparable,
useful for locating classifications and attributes sharing a common context,
groups: into which concepts sharing a common context are collected.
