Service integration, the ultimate goal of Shanghai Grid, has created a necessity for more efficient and effective workflow infrastructure. Workflow design tool is one core compone...
Vector data represents one major category of data managed by GIS. This paper presents a new technique for vector-data display that is able to precisely and efficiently map vector ...
While sketches are commonly and effectively used in the early stages of design, some information is far more easily conveyed verbally than by sketching. In response, we have combi...
Three-dimensional maps are fundamental tools for presenting, exploring, and manipulating geo data. This paper describes multiresolution concepts for 3D maps and their texture-base...
We describe a new, analytic approximation to the airlight integral from scattering media whose density is modeled as a sum of Gaussians. The approximation supports real-time rende...
