Multilayer hybrid visualizations to support 3D GIS

Abstract

In this paper we present a unique hybrid visualization system for spatial data. Although some existing 3D GIS systems offer 2D views they are typically isolated from the 3D view in that they are presented in a separate window. Our system is a novel hybrid 2D/3D approach that seamlessly integrates 2D and 3D views of the same data. In our interface, multiple layers of information are continuously transformed between the 2D and 3D modes under the control of the user, directly over a base-terrain. In this way, our prototype system is able to depict 2D and 3D views within the same window. This has advantages, since 2D and 3D visualizations can each be easier to interpret in different contexts.In this work we develop this concept of a hybrid visualization by presenting a comprehensive set of capabilities within our distinctive system. These include new facilities such as: hybrid landmark, 3D point, and chart layers, the grouping of multiple hybrid layers, layer painting, the merging of layer controls and consistent zooming functionality.

Hybrid Representation of Digital Mockup for Heritage Buildings Management

“…That's why we will opt for a job point of view; we will have a different representation for all the jobs working on the construction: this will be named "job views". In this idea, we will transpose the concept of layers like they are used in GIS (Brooks, 2008) in a 3D environment. They will be 3D-layers.…”

Molli: Interactive Visualization for Exploratory Protein Analysis

“…In combining abstract and spatial data aspects, Molli resembles other modern interactive visualization systems that have been applied to such diverse domains as visualizing brain connectivity in neural maps 4 or creating simultaneous 2D and 3D views of geospatial terrain data. 5 Molli is the first structure viewer we're aware of that enables multiple homologous proteins to be aligned and then their 3D models to rotate in concert. The closest work we could find to Molli was the SRS 3D module, 6 which also couples a sequence pane to the structure pane but can't link the views of homologous 3D models.…”

Towards Water Environmental Ontology Construction and Data Retrieval

“…The web portal of the Onto-WEDR was developed based on RIAs techniques and Microsoft.NET Framework (Version 4.5). In this work, we chose the Microsoft Silverlight as development platform because of its big advantages in rapidly building service-oriented applications [7]. Silverlight supports extensible application markup language (XAML), 2D and 3D graphics, animation, styles, data binding and other graphical control elements that are essential for application developers [8].…”
