Fully embedding wfds-ls1 on desktop and mobile devices
Early in the project life cycle it was requested by fire modelers that GMS examine fully embedding WFDS-LS within a mobile environment. The following key functional requirements for this mobile application were identified as follows:
? Visualizing shapefiles, ERDAS Imagine, GeoTiff, and web mapping services.
? Navigating and querying of data sources.
? Symbolizing shape and raster data sets by attribute values.
? Viewing cross sections of digital elevation models and other three-dimensional (3D) data sources.
? Visualizing 3D information overlaid with imagery.
? Adding multiple layers to the 3-D and profile views with ability to toggle the visibility of these layers.
? Editing and creating features.
? Saving workspaces for later use.
? Creating WFDS input files from input data over specified geographic extents.
? Viewing multiple WFDS simulation output files in the same view.
? Embedding WFDS-LS1 algorithms into application.
? Animating outputs from WFDS simulations.
? Zipping a project workspace for distribution to collaborators.
? Creating custom data collection schemes and sharing these amongst applications. Custom data collection schemes include the following:
o Single, Single Choice, Multi-Choice or Image Fields.

The full testing and procedures utilized for fully integrating WFDS-LS1 into the prototype desktop application and GIS-FMI are described in this report. The integration of WFDS-LS1 also occurred in the cross platform application. GIS-FMI is available for download free of charge on the App Store. This effort highlighted the possibility of implementing WFDS-LS1 as well as WFDS-LS2 in a mobile environment but speed of execution on a mobile device remains an issue. Fully embedding WFDS-LS3 and WFDS-LS4 on a mobile device would be difficult if done outside of the FORTRAN development environment due to the complexity of the code base.
