Multilayer hybrid visualizations to support 3D GIS

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...

3D texture-based hybrid visualizations

In this paper, the visualization of hybrid scenes that contain volume data and a fitted extracted surface is addressed. The proposed algorithm is based on a integrated octree-based representation: the ‘‘hybrid octree.’’ The hybrid octree allows to obtain multiresolution representation of the volume data and it also maintains a decimated surface codification. The proposed visualization approach ...

A Multi-stage Collaborative 3D GIS to Support Public Participation

This paper presents a collaborative 3D GIS to support public participation. Realizing that public-involved decision making is often a multi-stage process, the proposed system is designed to provide coherent support for collaborations in the different stages. We differentiate ubiquitous participation and intensive participation, and identify their suitable application stages. The proposed system...

Prediction of daily evaporation using hybrid support vector regression-firefly optimization algorithm and multilayer perceptron

Prediction of daily evaporation is a valuable and determinant tool in sustainable agriculture and hydrological issues, especially in the design and management of water resources systems. Therefore, in this study, the ability of artificial intelligence models of multi-layer perceptron (MLP), support vector regression (SVR), and the hybrid model of support vector regression-firefly optimization a...

An Empirical Study of Task Support in 3D Information Visualizations

There is still little knowledge about what factors are important for the usability of a 3D user interface. We have performed a comparative study of three 3D information visualizations as a step towards a better understanding of this. The study involved 25 volunteer subjects, performing three di erent tasks with the Information Landscape, Cam Tree, and Information Cube. The results of the study ...
