Deliverables: Standard Vocabularies 2.3.5 of the GLD WG Charter addresses the use of standard vocabularies for handling geographic concepts and geospatial data.

Geographic terminologies

These describe types of features, e.g. named topographic/planimetric features and points of interest

Types of features:

  • Political and Administrative Boundaries
  • Hydrography
  • Transportation
  • and other terminologies, e.g. along lines of efforts by UK Ordinance Survey and US FGDC A-16 Framework Data Themes

Ongoing Efforts in Geographic Terminology

Notable efforts in government to develop ontologies for geographic features include:

Geospatial Features

These describe feature geometry, e.g. point/line/polygon/topology/surface and other types of entities that would typically be represented via GIS or remote sensing data structures.

  • Simple Features, e.g. WGS84 lat/long
  • Complex Geodata, e.g. polygonal data
  • Spatial reference systems, e.g. EPSG and other designators for spatial reference systems
