Evolution of open-source web GIS technology in integration with contemporary commercial solutions not only provides an immediate solution at every level of small and medium-sized industry but also attracted students/scholars from a diverse background (Computer Science, Information Technology, Electronics, Civil Engineering, Geography, Geomatics, Earth Sciences, Hydrology etc) who are interested in making their carrier in different government (ISRO, DRDO, NIC, State Disaster Mitigation Centers, State Remote Sensing Centers etc) and private organisations (ESRI, Hexagon, Wipro, TCS etc). Proposed publication Concepts and Application of Web GIS emphasises both the basic principles and practical application of Web GIS technology for estimating the developments and advances about the use of both the commercial and open source Web GIS technology. It starts with describing the evolution of Web GIS technology, depicts its important uses/application in integration with Remote Sensing & GIS, discuss the role of Web GIS technology in current Smart City Services and E-Governance solutions and guide new developer to establish a complete Web GIS solution for their desired problem. Overall the book is a comprehensive solution for academia, commercial and planning community, which fills a long felt gap in the field of Geoinformatics and Web GIS community. Chapters written by active researchers presented in a way accessible to a public beyond those who are specialists in the topic dealt. Beside these, it will prove as a valuable reference book for graduation as well as post-graduation students to cover the syllabi related to technologies for GIS and Web GIS.
