Web service provides easy access to remotely requested functions. Integration of Web-Based service with GIS technology is advantageous, by maintaining a single centralized database, low cost of hardware/software, ease of use and wider access to GIS data and functionality. Geospatial Web services could be classified as Map/Data Oriented Services such as, map services (image), feature services (vector) and coverage service (grid); and Task Oriented Services such as Geocoding services, Routing services and geo-processing services. Accrete Geo integrates GIS with Web services and facilitates internet/intranet web-mapping, geoportals, application services and location-based services.
