Web GIS in practice VII: stereoscopic 3-D solutions for online maps and virtual globes

Because our pupils are about 6.5 cm apart, each eye views a scene from a different angle and sends a unique image to the visual cortex, which then merges the images from both eyes into a single picture. The slight difference between the right and left images allows the brain to properly perceive the 'third dimension' or depth in a scene (stereopsis). However, when a person views a conventional ...

Beyond Visualisation – 3d Gis Analyses for Virtual City Models

The successful utilization of 3D city models for business processes of urban planning highlights the benefits of 3D city models. This paper presents an overview of 3D GIS analysis capabilities for 3D city models. Based on realistic case studies the range of 3D analyses is highlighted and structured into categories.

3 D GIS , where are we standing ?

1. Introduction Since early '90 GIS has become a sophisticated system for maintaining and analysing spatial and thematic information on spatial objects. The need for 3D information is rapidly increasing. 2D GIS analysis has shown its limitations in some situations, e.g. noise prediction models (noise spreads out in three dimensions) (Kluijver and Stoter, 2003), water flood models, air pollution...

Performance Visualization : 2 - D , 3 - D , and Beyond

During the past ten years, performance data vi-sualization techniques have evolved from static, two-dimensional graphics to dynamic graphics and im-mersive virtual environments. We sketch the domain of applicability for each visualization technique using analysis of input/output behavior and WWW traac as example problem domains. With this background, we describe experiences with virtual environ...
