Prior to 1999, Arkansas lacked a National Spatial Data Infrastructure clearinghouse node. The Center for Advanced Spatial Technologies proposed the establishment of a clearinghouse node to make geospatial data and metadata for Arkansas widely accessible and to increase awareness of existing data around the State. The Arkansas GeoLibrary was an effort to develop a web-based metadata clearinghouse for the state of Arkansas.
The Arkansas GeoLibrary node of Clearinghouse was registered in 1999, with the support of the Federal Geographic Data Committee (FGDC). It grew to an archive of over 800 metadata records, which, due to the fact that these records document seamless statewide data layers, represented over 15,000 metadata records in a traditional archive. The node provided OGC web mapping services (WMS) and OGC web feature server (WFS) capability as well as OGC Style Management under OWS 2. Software developed at CAST in the course of several FGDC Cooperative Agreements projects, allowed metadata records to be quickly updated, added, and indexed in the Arkansas GeoLibrary Clearinghouse node. Currently all geospatial data and metadata for Arkansas are available from the state of Arkansas' Arkansas GeoStor System Release 6.
Development of this Clearinghouse was funded by the FGDC whose assistance is gratefully acknowledged!
