Incident process steps 1–2: Get incident location and create buffer (own figure). The web application shows the indicators: Location of incident (longitude, latitude) and buffer in metres. The code excerpt displays a .geojson file containing information for a simulated incident (incident ID, incident name, longitude, and latitude coordinates). The map output visualises the location of the incident on the Tyne Bridge with a red marker and a red circular buffer area around the incident location. KW created the map output using the Microsoft Azure Maps Web Software Development Kit and TomTom (© 2022) base map data (a subscription key to use the data can be obtained after registering on the Azure Maps platform for Geospatial Mapping APIs under https://azure.microsoft.com/en-us/services/azure-maps/#azuremaps-overview). The code for the web application was developed in JavaScript, CSS and HTML in the Microsoft Visual Studio Code integrated development environment (version 1.70.2) and Node.js (version 16.13.2) on a Windows NT 64-bit operating system (×64-based processor)40.
