SwissGeolWebMap

A web map application for geologists, designed to visualize geological data layers. It allows users to apply attribute filters based on vocabularies like Chronostratigraphy, Tectonic Units, Lithostratigraphy, and Lithology. The map also features a popup that displays augmented data (such as ID, LitoDE, LitoEN, TectoLexic, etc.) upon clicking a point on the map.

Getting Started

First, create a .env.local file by copying .env.example and fill in the required environment variables.

Then, run the development server:

npm run dev

Open http://localhost:3000 with your browser to see the result.

Docker

To run the application using Docker, you can set the environment variables directly in the docker-compose.yml file.

Note: The NEXT_PUBLIC_GEOSERVER_BASE_URL variable must be passed as a build argument (using args in the build section). This is because it is required by Next.js during the build process to be embedded in the client-side code. It is not needed as a runtime environment variable. The docker-compose.yml files are already configured for this.

Then, run the container:

docker-compose up --build

The application will be available at http://localhost:3050.

Environment Variables

The application is configured via environment variables. When using Docker, these are set in the docker-compose.yml file. For local development, they should be in an .env.local file.
