To develop a web based system that implements a "navigate-and-choose" paradigm and allows the end user to:
  • Select (a set of) computational modules that provide answers to the problem at hand
  • Retrieve input data sets from remote sources
  • Use adequate (remote) computational resources
  • Visualize and analyze output data on the local host
Anytime, anywhere, using any platform
(e.g., a connected to the internet laptop PC)

Foil 59 LMS: Changes in Vegetation

From Summary of NPAC Year 3 Activities at Cewes Cewes PET Annual Meeting -- February 9-10 1999. *
Full HTML Index
A decision maker (the end user of the system) wants to evaluate changes in vegetation in some geographical region over a long time period caused by some short term disturbances such as a fire or human's activities.
One of the critical parameters of the vegetation model (EDYS) is soil condition at the time of the disturbance.
This in turn is dominated by rainfalls that possibly occur at that time (CASC2D simulation)
Input data for the simulations are available from the Internet, such as Data Elevation Models (DEM) from USGS web site or from custom databases (spieces characteristics)
