WinDisp was originally developed for the FAO Global Information and Early Warning System. The European Commission was the primary source of funds for the development of the GIEWS Workstation and WinDisp4.0.


Many organizations contributed to the development of WinDisp3.x and WinDisp4.0. WinDisp has been developed in co-operation with:

FAO logo The FAO Africa Real Time Environmental Monitoring Information System (ARTEMIS)
USAID logo The USAID Famine Early Warning System (FEWS)
SADC logo
The Southern African Development Community (SADC)
USDA Forest service logo
The USDA Forest Service (USFS)
The US Geological Survey (USGS) EROS Data Center


WinDisp was developed by Eric Pfirman, Justin Hogue and Linda See. Improvements implemented in versions 3.x and 4.0 included the transfer of functions from the IDA software originally developed for FEWS by Eric Pfirman, Richard Collins and Justin Hogue. The SEDI routines included in version 3.5 and above were developed by Peter Hoefsloot and derived from the IDA GIS Tools software routines originally developed for the Southern African Development Community (SADC).

Eric Pfirman maintains a developers website at http://Ag.Arizona.Edu/~epfirman/ which provides updates and information concerning the latest developments in WinDisp, as well as the current version of the software along with beta versions of upcoming releases for testing.

Documentation, including on-line help, reference materials and the WinDisp 4.0 User Manual were developed by Eric Pfirman and Isabelle Charlier. Translations were done by Isabelle Charlier, Linda See, John Lewis and Andrés Ravello.

The User Manual was developed to provide an introduction to WinDisp Version 3.5 to new users, while also providing some in-depth background and reference materials for advanced users of the program. An updated manual accompanies Version 4.0 and includes information and instructions on the new features added to Version 4.0. This manual builds upon the previous reference materials distributed with the software by Eric Pfirman, and the IDA for DOS Version 4.2 User Manual developed for FAO ARTEMIS by Peter Hoefsloot.

The WinDisp Web site has been prepared by Philippe OSSWALD.
