This document discusses how Mouchel, an infrastructure consultancy, uses FME (Feature Manipulation Engine) software in their work. Some suitable tasks for FME include repetitive tasks, tasks done over many catchment areas, tasks with changing variables, and tasks that follow strict procedures. Flood risk mapping is one major use of FME - it involves using spatial data and models to identify properties at risk of flooding and simulate different rainfall scenarios. FME is used for data preparation, transformation, running simulations, and post-processing results, helping Mouchel efficiently handle "big data" and deliver flood risk information and analyses to clients.

FME?

4. Suitable for FME?
Tasks suitable for FME:
• Repetitive tasks
• Same task over many catchments
• Monotonous tasks
• Strict procedures to specifications
• Tasks with changing variables
• Large datasets
Tasks NOT suitable for FME:
• Iterative processes (unless staged)
• Simple one-offs
• Quicker to do in GIS (e.g, MapInfo)
• Requires engineering judgement

12. Flood Risk Mapping
• To identify individual buildings/properties at risk
• Allows modelling of above ground flooding schemes
• Gives a graphical representation of flow paths
• Helps clients achieve regulator requirements
• Provides a basis to build up cost/benefit reports to prioritise investment in the network.
