Academic Editor: Wolfgang Kainz Received: 19 March 2016; Accepted: 26 May 2016; Published: date Abstract: One of the most widely-implemented service standards provided by the Open Geospatial Consortium (OGC) to the user community is the Web Map Service (WMS). WMS is widely employed globally, but there is limited knowledge of the global distribution, adoption status or the service quality of these online WMS resources. To fill this void, we investigated global WMSs resources and performed distributed performance monitoring of these services. This paper explicates a distributed monitoring framework that was used to monitor 46,296 WMSs continuously for over one year and a crawling method to discover these WMSs. We analyzed server locations, provider types, themes, the spatiotemporal coverage of map layers and the service versions for 41,703 valid WMSs. -

Location intelligence is: • An awareness of relationships between location information and business analysis and operations • The ability to use the understanding of geographic relationships to predict how it impacts a business or organization • The capability to react to how location influences an organization by changing business processes in order to minimize risk and maximize opportunities Location Intelligence enables a business to measure, compare and analyze its data from business operations, in conjunction with external data such as transportation networks, regulatory jurisdictions, market characteristics or its own customers. In this section 2 - What is Spectrum Spatial? Spectrum Spatial is an enterprise location intelligence platform designed to provide organizations with a suite of broadly applicable location capabilities, including spatial analysis, mapping, routing, geocoding, and geoprocessing. -
