Radarmap

A visualization application for RADVOR radar open data by the German Weather Service (DWD). This is not affiliated with DWD in any way.

Overview

Radarmap is designed to provide smooth, low-latency access to precipitation intensity (RQ) and type (RE) forecast data. It leverages a modern stack to handle heavy coordinate transformations and tile rendering efficiently.

This is not production software in any way. This is mostly a playground for me to check out tileservers as backends, take them apart and profile them.

Project Structure

• radarmap-backend/: FastAPI server responsible for data parsing, georeferencing, and tile rendering.
• radarmap-frontend/: React application providing the map interface and timeline visualization.

Performance & Scaling

Radarmap is built as a benchmarking platform. It features multiple render paths to compare CPU (NumPy) vs. GPU (Numba CUDA) rendering performance.

Getting Started

1. Ensure you have uv installed.
2. cd radarmap-backend
3. uv sync
4. uv run uvicorn app.main:app

Frontend

1. cd radarmap-frontend
2. npm install
3. npm run dev
