This document describes the FAST (Flood Awareness and Susceptibility Tool) modeling tool box. It discusses OpenEarth, an open source community for sharing data, models, and tools. FAST will utilize OpenEarth components like standardized data formats, version control systems, and OGC web services. The tool will allow users to input elevation, vegetation and other data to model flooding and erosion. It will include a basic web interface and access to models like XBeach via OGC web processing services. The document outlines FAST's data and architecture, and next steps to refine models and ingest additional data.

Editor's Notes
- #13: What is WPS In many cases geospatial or location data, including data from sensors, must be processed before the information can be used effectively. The OGC Web Processing Service (WPS) Interface Standard provides a standard interface that simplifies the task of making simple or complex computational processing services accessible via web services. Such services include well-known processes found in GIS software as well as specialized processes for spatio-temporal modeling and simulation. While the OGC WPS standard was designed with spatial processing in mind, it can also be used to readily insert non-spatial processing tasks into a web services environment. The WPS standard provides a robust, interoperable, and versatile protocol for process execution on web services. It supports both immediate processing for computational tasks that take little time and asynchronous processing for more complex and time consuming tasks. Moreover, the WPS standard defines a general process model that is designed to provide an interoperable description of processing functions. It is intended to support process cataloguing and discovery in a distributed environment.
