Urban landscape 3D visualization system is the basic support system of Digital City, Digital China or Digital Earth, its research is also the key issue in the field of digital city. Therefore, this article selects urban landscape three-dimensional visualization system as research object In-depth analysis of R & D requirements of urban landscape 3D visualization system, the paper examines in detail the basic system structure, key technology, and targeted improved and optimization in its data management, event handling, and three-dimensional visualization engine, the effectiveness of these methods is proved in practice. On the other hand, the content of this article is only involved based part in urban landscape 3D visualization system, the parts solved includes the system infrastructure and visualization engine, while automatic scene construction and knowledge expression issues remain to be a further study.

In this work, we introduce EdgeMaps as a new method for integrating the visualization of explicit and implicit data relations. Explicit relations are specific connections between entities already present in a given dataset, while implicit relations are derived from multidimensional data based on shared properties and similarity measures. Many datasets include both types of relations, which are often difficult to represent together in information visualizations. Node-link diagrams typically focus on explicit data connections, while not incorporating implicit similarities between entities. Multi-dimensional scaling considers similarities between items, however, explicit links between nodes are not displayed. In contrast, EdgeMaps visualize both implicit and explicit relations by combining and complementing spatialization and graph drawing techniques. As a case study for this approach we chose a dataset of philosophers, their interests, influences, and birthdates. By introducing the limitation of activating only one node at a time, interesting visual patterns emerge that resemble the aesthetics of fireworks and waves. We argue that the interactive exploration of these patterns may allow the viewer to grasp the structure of a graph better than complex node-link visualizations.

Our paper addresses problem of multi-modal data acquisition and the following datavisualization for art analysis and interpretation. Various types of modalities for acquisition of digital images are used for art analysis. The data we can obtain using various modalities differ in two ways. The acquired images can differ by their mutual geometry and possibly by their radiometric quality. These are the differences we would like to remove. The group of differences we are interested in are details or characteristics of an artwork, which are apparent just in the certain modality and which bring us new information. The two listed groups represent two categories of image processing methods we have to deal with. The first one is represented by image preprocessing methods such as data enhancement and restoration algorithms, the second class includes effective ways how to combine the acquired information into one image - image fusion. In our paper we present image quality enhancement for microscopic multi-modal data and their segmentation and recent results in data fusion and visualization for art analysis are demonstrated from the second category of methods.
While much work has been done in the area of visualization for analysis of graphs, relatively little research exists into how best to use visualization for comparing graphs. We have developed a suite of general graph ...
