Geography and Spatial Information
Deliverables: Standard Vocabularies 2.3.5 of the GLD WG Charter addresses the use of standard vocabularies for handling geographic concepts and geospatial data.
These describe types of features, e.g. named topographic/planimetric features and points of interest
Types of features:
- Political and Administrative Boundaries
- 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:
- UK Ordinance Survey
- USGS National Map
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
