Web Based Land Information System for Nintavur Divisional Secretariat Division (DSD), Sri Lanka

Abstract

Nowadays, Web-based Land Information System is important to learn about the use of Geographic Information Systems and software for our profession. Modern technologies like geo-data processing, earth observation data processing and analysis are needed for Sri Lankan young researchers and students. This research work is dedicated to develop a land information system of Nintavur DSD. One task of the work is to establish a land information database which is based on an Open Source Geographic Information System. Work is starting with acquisition of existing geodata and information, qualification, maintenance, utilization and transferring of data from Nintavur DSD. The establishment of a land information system for Nintavur DSD will contribute to the National Land Information System of Sri Lanka. The study demonstrates that Land Information Systems can be developed using GIS software as e.g. QuantumGIS, and the Open Source database management system Postgre SQL /Post GIS and Arc GIS. This paper presents a framework for a Web-based GIS for Land Information. It focuses on the underlying concepts, theories and techniques for designing and implementing the conceptual Original Research Article Kaleel and Zahir; JGEESI, 5(4): 1-6, 2016; Article no.JGEESI.20748 2 framework that called WebGIS Land information. It consists of two main elements supporting the deliberative and analytic components of decision-making process. The deliberative part is based on the concept of argumentation maps. The analytic component consists of decision analysis methods. WebGIS Land information uses the server-side architecture approach to Web-based GIS. It employs HTML, CSS and JavaScript on the client-side and a combination of PHP scripting language, Map Server and a Postgres Sql database on the WebGIS Land Information.
