City Information System Using Internet GIS - A Case Study of Visakhapatnam City Rambabu Palaka A.M.I.E. (Civil), M.Tech (Remote Sensing) Municipal Assistant Executive Engineer Email: palaka_rambabu@yahoo.co.in Dr. G. Jai Sankar M.Sc., Ph.D., Associate Professor Dr. E. Ammineedu M.Sc., Ph.D., Associate Professor Head of the Department Department of Geo-Engineering Andhra University, Visakhapatnam Andhra Pradesh, India Abstract For many years, we have been seeing isolated groups using GIS. These groups include System users, System operators, GIS suppliers, Data supplier, and Application developers. But, In addition to the above groups, a common citizen may also want benefit from GIS. He/she may want internet access to view maps including Locating a ward, Locality, Landmark, Building, Parks, Shortest and Quickest path between two locations, Search buildings or landmarks nearest to his location etc., To fulfil all his needs, the only solution is “Internet GIS”. To meet some of needs of a common citizen, a case study was taken up with Visakhapatnam City. Visakhapatnam, City of Destiny, is located 83012’ E to 830 21’ E Longitude and 170 40’ N to 170 45’ N Latitude. For this project, we have collected data from Visakhapatnam Municipal Corporation, a Local body of Andhra Pradesh State Government. This Corporation has 50 election wards spread over an area of 110 Sq. Km. This project was taken up with Microsoft Dot net technology for application development with the help of AspMap 3.0, a third-party component. Spatial data used in this project are in Shape file format (Converted from MapInfo Tab files) and non-spatial data is maintained in SQL Server 2000 database. The concept of dynamic maps is used here. All point data such as landmarks, buildings etc., are represented in database tables. Remaining polygon and line data such as city boundary, ward boundary, localities, road net work etc., are represented on Shape file format.

For this, road network was built using Road Network builder tool of Aspmap 3.0 component. Prior to this, road class, speed and one-way route information was updated in Roads shape file. Case Study Project URL: www.saukaryam.com/igis/home.aspx Scope of Work
Index Map
Buildings like Government, Residential, Commercial, Education, Recreational, Worship, Emergency etc., can be shown which exists in the selected locality. Search Building based on House No Search Building based Longitude and Latitude Insert / Draw Graphics Basically this option is used to locate an object based on its co-ordinate points. e.g., if user enters the co-ordinates of the building four corners, the building shape can be displayed in the map. BUFFER ANALYSIS Search Nearest Buildings From Selected Landmark Shows List of Buildings of selected building category which are nearer (with in the radius) to a selected landmark in the city. Search Nearest Buildings From Selected House No Shows List of Buildings which are nearer (with in the radius) to a required House No. in the city. Search Nearest Landmarks From Selected House No Shows List of Landmarks which are nearer (with in the radius) to a required House No in the city. Application Development
