for developing web mapping applications. An attempt was made by simhachalam et al.,2014 to build a web mapping application using ArcGIS technologies that would help decision makers in the government sectors to implement proper planning and arrangements [1]. An implementation of a web based interface was carried out by Xingguo et al. for building a thematic atlas on the web using ArcGIS API for Flex and ArcGIS server to facilitate decision making [10]. A web application for coalfields based on Silverlight API was developed for thematic viewing, querying and displaying statistical information by consuming map and image services published using ArcGIS server [3]. References in this paper leads to many other papers where ArcGIS technologies have been utilised for developing web applications but none mention about the huge costs incurred if an organizations prefers to buy a licence for this server.
