TRANSPORTATION SPATIAL DATA DICTIONARY (DRAFT)

This Transportation Spatial Data Dictionary, developed by the Federal Geographic Data Committee's (FGDC) Ground Transportation Subcommittee, is a first step toward standardizing definitions and spatial object presentations for transportation features. Each transportation feature in this dictionary has a standard term, a definition for that term, and a spatial presentation. The spatial presentation identifies one or more spatial objects used to represent the feature in geo-spatial database. Headings covered in the table of contents include: Review Process, Spatial Presentation Definitions, Spatial Features, Accident Site, Airport, Bridge, Crossing, Harbor, Intermodal Transfer Facility, Junction, Linear Reference Point, Lock, Pipeline, Port, Railway, Roadway/Highway, Route, Runway, Terminal, Trail/Path, Transportation Facility, Transportation System, and Transit Guideway.
