Exchange Network partners have identified various issues associated with the use and exchange of geospatial data on the Exchange Network. In late 2006, the Exchange Network Leadership Council (ENLC) convened an Exchange Network Geospatial Strategy Team to examine the following issues:
- What are the best options for encoding geospatial data for exchanges on the Exchange Network?
- What are the challenges and options associated with multiple coordinate reference systems used by EPA, States, tribes, and others to represent geospatial data of interest in exchanges on the Exchange Network?
The team issued its report to the ENLC in July of 2007 and recommended adopting Geography Markup Language (GML) as the standard for sharing geospatial data over the Exchange Network. Furthermore, the team recommended exploring the use of GeoRSS GML (a specific sub-set of GML) where expression of simple geospatial data in Exchange Network flows is required.

The Exchange Network Geospatial Task Force is currently exploring the recommendations contained in the Strategy Team's Report in an effort to provide further clarity and explicit guidance to Exchange Network partners seeking to exchange geospatial data. More information will be posted here as it becomes available.
The Geospatial Task Force Phase 1 Scoping and Demonstration Group has a wikispace: http://geotf.wikispaces.com for sharing information. This is currently a private wikispace. If you would like access to it, please email or call Shawna McGarry at Ross & Associates (email: shawna.mcgarry@ross-assoc.com, phone: 206.447.1805).
