An interactive, three-dimensional graphic interface was conceived and developed, to illustrate and enable exploration of events recorded in a genealogy. The resulting visualization provides a colorful and intuitive view of migrations, as well as plotting the biographical data for individuals in the genealogy. Users can quickly highlight the connections between people, get a perspective on which...

We present an overview of an ongoing project to build DDDAS to use all available data for a short term wildfire prediction. The project involves new data assimilation methods to inject data into a running simulation, a physics based model coupled with weather prediction, on-site data acquisition using sensors that can survive a passing fire, and on-line visualization using Google Earth.

However, to date there are no suitable approaches available for mapping Torreya forest distribution, especially the new Torreya plantation...

The mapping of squatter settlements has been a difficult task for geographers (Manoj, 2008). This is due to the dynamic nature of the settlement and the organic growth that these types of settlements take on (Brian, and Ranvinder, 1995). It has proven extremely difficult to accurately map individual households in these settlements and even boundary discernment can be difficult. These issues of ...

Visibility analysis or Viewshed is a common function of almost all GIS systems. The aim of this project is to find out the best solution, to compute viewshed for the Olomouc region and ensure the best way of visualisation of the results. The first step to analyze the visibility is making a high quality Digital Terrain Model, choice of the best interpolation method and subsequent addition of veg...

Spartina alterniflora (S. alterniflora) is one of the most harmful invasive plants in China. Google Earth (GE), as a free software, hosts high-resolution imagery for many areas of the world. To explore the use of GE imagery for monitoring S. alterniflora invasion and developing an understanding of the invasion process of S. alterniflora in the Zhangjiang Estuary, the object-oriented method and ...
