Introduction
A central goal of EU INSPIRE is to promote the sharing of data in order to better manage natural environments and impacts related to human security. Historically, some of the largest impacts to human settlements in Europe are due to natural hazards such as flooding, and these impacts are only increasing with climate change. There is a growing need for tools to inform the public and decision makers about flood extents and impacts. While there is a range of INSPIRE themes related to flood management, there are also real-time event-based services that need to be incorporated in order to monitor and respond to flood events adequately.
The following exercises demonstrate how to build a web app called the Flood Warning Assistant. This app displays current and past flood extents, and also assesses potential impacts on roads and other infrastructure. To do this, it integrates required INSPIRE themes with other national datasets and event-based warning services necessary to support flood warning display and impact assessment.
Data Sources
The flood warnings come from a UK Environment Agency REST service, Finnish historical floods from the National Land Survey of Finland (WFS3), and roads/infrastructure information from UK Ordnance Survey OpenData products (OS Mastermap GML). The basic design involves four basic components: basemap database loading, real-time flood warning updates from REST service, interactive web map display, and analysis and distribution via HTML reports.
Currently, the demo has live data for UK and historical for Finland, but most of the infrastructure related data is only loaded for central England (Birmingham, Peterborough etc).
Exercises
The following are the exercises break down the application development into 3 main exercises. Each comes with starting workspaces and source data and can be used as a stand alone exercise, or they can be done in sequence and the output of one used as the input of the next step.
Exercise 1: Data Extraction and Loading
Exercise 2: Live flood warning data feed to Geopackage
Exercise 3: Flood and impact HTML report generator
