Spatial progression of estate property management system with customized freeware GIS

摘要

Estate property management system mainly deals with geographical area with associated information for monitoring and managing estate properties. Geographic Information System (GIS) has potential to handle spatial and aspatial data in a single platform which makes GIS a favourable choice for estate property management system. The availability of free and open source GIS helped this technology affordable and popular in large number of applications. Hence there is a demand to develop a new or upgrade an existing non-GIS based system to a GIS based property management system. In this paper a novel case study is presented where an Oracle based system is integrated with GIS platform using freeware ArcGIS Explorer (AGX) customization. The integration of dynamic data from Oracle server is challenging due to non-supportive database type in AGX. The issue is overcome by introducing an intermediate file handling mechanism in the GIS interface using Oracle client in .net frame work. The proposed system can run in multiple nodes in a local area network and capable of fetching data from Oracle server. It serves user queries on both spatial and aspatial data that enables spatial visualisation of aspatial data.
