Site Selection Ring Analysis with Esri ArcGIS. The MMB application consumes, analyzes, reorganizes, and enhances this information to deliver economic development information to users. MMB’s software architecture is based on a geospatial service-oriented architecture (SOA). Analysis and reporting is executed using several distributed web services. MMB pulls information from the state-wide cadastral web service, ESRI ArcWeb Services Business Analyst Online (BAO), and services made accessible through the State’s Department of Labor. The geospatial SOA foundation has allowed MMB to expand and extend analysis and reporting, as well as use additional mapping viewers as technologies unfold and new partnerships are formed. In December 2008, GCS extended MMB to use Google Maps and the browser-based Google Earth plug-in.
