Abstract
Abstract. Different applications or users need different model (differ requirement on level of details; geometry and information), less focuses in topological element. Improper manage geometry, attribute and topology elements in multi-scape environment will cause data repetition/redundancy, storage capacity and performance issues. This research focuses on utilizing topological graph which is important for various Geographical Information Science applications such as 3D indoor, network analysis, and sharing information/attribute from multiple level of details (LoD). A conceptual framework towards a unified data structure/model for representing several levels of details (LoDs) which integrates 2D and 3D topological and geometrical spaces in a single view is presented. The proposed framework has a potential of adopting into the CityGML/IndoorGML standards with representing different CityGML LoDs in a single view representation. Potential applications of the proposed conceptual framework including solar energy and utility mapping are discussed.
