Abstract:

In this developing era of modern trend of urbanization and industrialization there is an emergent need for proper city planning systems. 3D models are digital representations of the Earth’s surface and related objects belonging to urban areas on the earth surface. 3D models are real world representation useful in applications such as 3D visualization, planning the city in Infrastructure development, Information system for tourism, Intelligent transportation systems, Environmental aspects, Disaster Management, public rescue operations, real estate market, utility management, Military operations, Training of officers, Simulation of new buildings, Updating and keeping cadastral data, monitoring change detection and virtual reality. LiDAR data (Light Detection and Ranging) is a recent new technology for obtaining the earth’s surface objects mainly for 3D building visualization. ALTM (Airborne Laser Terrain Mapping) data when combined with digital orthophotos can be used to create highly detailed Digital Surface Models (DSMs) and DEM from which Digital 3D City Models are obtained. Various techniques and conditions were used to extract the objects and accuracy level is examined. Research in 3D GIS helps to analyse the replica of real world and the related issues. Here, in this paper the 3D objects are developed using ArcGIS and also by using algorithm techniques.
