The expansion and growth of map services provides a new and exciting means for government to share and publish large amounts of geospatial data which in previous years was difficult to make available to end users. Current technology offers users a wide range of options to consume data-rich map services such as WMS (Web Map Services), ArcIMS Image or ArcGIS Server services, and other OGC compliant map service formats. Services can be used with either desktop applications or fused with other "live" internet map services covering the same geographic footprint. The growing popularity of viewing clients such as Google Earth, NASA WorldWind, ArcGIS Explorer, Microsoft Virtual Earth, GAIA 3, and OpenLayers provide opportunities for much greater exposure for map services. Metadata provides the conduit towards exposing and making map services (and associated data content) available to end users. Metadata records created for individual map services provide information on the map server URL, map service name, application URL, "key" words describing datasets used in the map service and other pertinent information. This presentation will provide a step-by-step overview of how local governments in the State of Ohio - with particular focus on those sites which currently support public facing map services - can become engaged in contributing metadata records through the Ohio GIS Clearinghouse which are then available through the Geospatial One Stop (GOS) portal.
