چکیده

This paper focuses on 3D data structures supporting an alternative approach for creating 2D vario-scale maps. The smooth animated zooming functionality have lead us to investigate a volumetric representation of gradually changing vario-scale objects. In this paper, the principle of vario-scale maps with theoretical knowledge about 3D representation (2D space plus 1D scale) is briefly introduced, followed by a description of our initial implementation efforts for creating a development environment for our research, which is based on the conversion from the classic tGAP data structure through tetrahedralization to a volumetric representation. The current results and examples of this volumetric representation with real world data and plans for future improvements are presented.

Vario-scale data structures supporting smooth zoom and progressive transfer of 2D and 3D data

This paper introduces the concept of the smooth tGAP structure represented by a space-scale partition, which we term the space-scale cube. We take the view of 'map generalization is extrusion of data into an additional dimension'. For 2D objects the resulting vario-scale representation is a 3D structure, while for 3D objects the resulting vario-scale representation is a 4D structure. This paper...

Developing a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information

With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...

Target detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV

In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...

A Matrix-Based Structure for Vario-Scale Vector Representation over a Wide Range of Map Scales: The Case of River Network Data

The representation of vector data at variable scales has been widely applied in geographic information systems and map-based services. When the scale changes across a wide range, a complex generalization that involves multiple operations is required to transform the data. To present such complex generalization, we proposed a matrix model to combine different generalization operations into an in...
