Repository: VISTA
Description: Vista is a web application used to evaluate high value assets
SPDX-License-Identifier: Apache-2.0 AND OGL-UK-3.0
VISTA is a digital mapping tool designed to assess, visualise, and simulate cascading asset failures during emergencies. It enables real-time monitoring of infrastructure dependencies, illustrating how disruptions to key assets - such as roads, energy grids, and healthcare facilities - affect interconnected services and communities.
In addition to assessing failures, VISTA provides predictive capabilities, allowing users to simulate a range of emergency scenarios. By integrating real-world and simulated data, VISTA enables proactive planning, helping emergency responders, infrastructure managers and policy officials anticipate how disruptions propagate and optimise response efforts before incidents occur.
For guidance using VISTA, refer to the user guides directory.
Vista comprises four main components:
- Frontend: A React application found in
frontend. - Backend: A Python API used to provide or proxy various APIs outside the security perimeter, found in
backend. - Kubernetes Manifests: Deployment and runtime manifests for services, located in
k8s. - Transparent Proxy: A proxy component for handling API requests, found in
transparent-proxy.
For detailed setup instructions, please refer to the SETUP.md file. Here's a brief overview:
-
Prerequisites: Ensure you have Node.js, npm, Yarn, Python ^3.12.5, Poetry, Docker, and AWS CLI installed.
-
Frontend Setup: Navigate to the
frontenddirectory, configure npm and Yarn with GitHub packages, install dependencies, and start the application. -
Backend Setup: Set up AWS credentials, login to AWS ECR, and follow the instructions in
backend/vista-python-api/README.md. -
Transparent Proxy Setup: Build the Docker image (located in
transparent-proxy/Dockerfile) and run the container with required environment variables.
For more detailed information on each component, please refer to their respective README files in their directories.
- For updating Python requirements, refer to
backend/vista-python-api/docs/updating_requirements.md. - To create a towncrier entry:
