Geolinking Service

Discussion Paper
Description
 

The Geolinking Service takes the attributes found in a set of geolinked data and merges them with a related set of geospatial data to produce a combined set of geospatial data which contains those attributes. The merging of these datasets is based on the use of a linkage field that is found in both sets of data. This service can be implemented to publish this information via an existing WMS.

A Geolinked Data Access Service normally provides the geolinked data. The related set of geospatial data may reside locally, or provided by a Web Feature Service.
