Concepts and Techniques of an Online 3D Atlas - Challenges in Cartographic 3D Geovisualization
نویسندگان
چکیده
To meet the challenges of future digital atlas publication, a concept for an online 3D atlas platform (APS) has been developed. This framework should have the potential for combining interactive thematic cartography with real-time 3D atlas technology. As to system design, the APS will consist of extensible modules for spatial navigation, map visualization and information retrieval, integrated in a Web application user interface. The modules will be developed gradually; core functionality will be implemented first and can be extended according to user needs. Currently, work is done on the visualization core module, allowing for 2D and 3D mapping by means of the Virtual Globe engine osgEarth. The visualization engine is capable of handling large amounts of geographical data and web services. Essentially, the system offers 2D and 3D visualization of raster data (DTMs, imagery, etc.), vector data (choropleths, univariate symbols and diagrams, POIs), and even 3D objects.

Development of an Anaglyph Anatomical Atlas of Rabbit as a New Generation of Printable 3D Anatomical Atlases
Introduction: To improve anatomical atlases, we tried to create a printable 3D atlas of rabbit's anatomy based on the Anaglyph. Methods: In this study, twenty white rabbits euthanized and dissected. All 3D images were reconstructed by means of "stereo photo maker (SPM®)" software. Results: By this atlas, users can easily understand nomenclature, the topography and, certainly, the transpo...
متن کاملA 3d Geovisualization Approach to Crime Mapping
This contribution presents an approach to visualize crime scene analysis results with three-dimensional geovirtual environments. Commonly, the results of those crime data analyses are published trough thematic maps. Therefore cartographic visualizations can be considered as a key element to communicate the outcomes of crime analysis. Those visualizations produced by crime analysts both in opera...

Spatial OLAP (SOLAP) systems do not completely integrate visualization, interaction and analysis functionalities of Geographic Information Systems. In this paper, we propose a flexible Web SOLAP tool, GoOlap, which combines OLAP and Geovisualization functionalities through the integration of the geobrowser Google Earth and the OLAP tool Mondrian/JPivot. Google Earth enriches spatio-multidimensi...

Despite considerable enhances in recognizing hand gestures from still images, there are still many challenges in the classification of hand gestures in videos. The latter comes with more challenges, including higher computational complexity and arduous task of representing temporal features. Hand movement dynamics, represented by temporal features, have to be extracted by analyzing the total fr...

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...
