DRIFT-X WPS: PESTICIDE ATMOSPHERIC DISPERSION WEB GIS
The original Drift-X model was coded in Fortran 77 by University of Montpellier 2. Drift-X is able to calculate windflows with a small number of wind points measurments, and according to the local topography provided by DEM layers. Then, the pesticide cloud is calculated according to the simulated windflow and depending on user parameters about phyto-treatments. It allows to forecast the trajectory and the position of a pesticide cloud in a georeferenced framework.
Drift-X WPS is based on the use of ZOO Project (zoo-project.org) for scientific computing. This application uses Drift-X Fortran model as a ZOO Service, thanks to the Fortran support in ZOO. ZOO Kernel is used to execute a set of five webservices composed of Fortran code, GDAL commands and various python scripts. On the client side, the ZOO API is used to set up and launch the webservices chaining and the atmospheric dispersion simulations are mapped with OpenLayers.
