zarr-gl-example

This is a basic example demonstrating data preparation for zarr-gl and loading in a simple no-build Maplibre website.

Steps (you're welcome to skip the bits you don't need or know how to do):

1. Install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

2. Clone this repository and move to this directory:

git clone git@github.com:carderne/zarr-gl.git
cd zarr-gl/example

3. Install Python dependencies:

uv sync

4. Inspect the script at ./data_prep.py and run it. It will generate a simple example dataset at ./example.zarr.

uv run python prep.py

5. Run a simple Python server in this directory:

uv run python -m http.server

6. And navigate to localhost:8000 in your browser. If all went well, you should see a simple red/green/blue gradient covering the world. Take a peek at index.html to see how it works.
