GIS-integrated environmental models Asensio Sevilla, María Isabel Prieto Herráez, Diego Álvarez León, David Ferragut Canals, Luis Cascón Barbero, José Manuel GIS integration High definition wind model Wildlfire spread model [EN]In this paper, we present the integration of the mathematical models Physical Forest Fire Spread (PhFFS) and High Definition Wind Model (HDWF), developed by the authors, into a GIS-based interface in order to supply to the end-user a func- tional and efficient tool. The resulting tool automates data acquisition, pre-processes spatial data, launches the aforementioned models, and displays the corresponding results in a unique environment. Our implementation uses the Python language and Esri’s ArcPy library to extend the functionality of ArcMap 10.4. The PhFFS is a simplified 2D physical wildland fire spread model based on conservation equations, with convection and radiation as heat transfer mechanisms. It also includes some 3D effects. The HDWF arises from an asymptotic approximation of the Navier-Stokes equations, and provides a 3D wind velocity field in an air layer above the terrain surface. Both models can be run in standalone or coupled mode. Finally, we confirm that the developed tool is efficient and fully operational presenting some examples of its successful application. 2018-08-31T06:47:37Z 2018-08-31T06:47:37Z 2017-06 info:eu-repo/semantics/conferenceObject M.I.
