COINAtlantic has introduced a local database viewer to its Search Utility (CSU) web-based application. Each result of a user’s search for WMS and KML resources using the Google Custom Search API or a user’s addition of a WMS layer using the “Add WMS Layer” widget is stored in a local PostSQL data base. A script has been developed to interrogate each of the resources on a daily basis and store the geographic bounds of the KML or the WMS layer. If the interrogation successfully returns the geographic bounds, a green status symbol is displayed in the CSU database viewer (see below). If the interrogation was successful but the bounds were not returned a yellow symbol is returned. A red symbol is displayed if the service did not respond. This capability is a precursor development to support reliability indicators displayed in the CSU user interface and will enable geographic searches of the local data base.
