# RF Propagation API
|
|
|
|
HTTP API for radio visibility, terrain profiles, Fresnel/LOS checks, link budget,
|
|
viewshed, and coverage calculations.
|
|
|
|
This repository follows `SPEC.md`. The first implementation pass creates the full
|
|
service skeleton, pure RF/math kernels, and Copernicus DEM sampling. Integrations
|
|
that require PostGIS data, pycraf, ITM/P.1812, landcover/canopy rasters, or
|
|
external viewshed binaries are exposed through stable interfaces and return
|
|
explicit "not implemented" responses until the corresponding data pipeline is
|
|
connected.
|
|
|
|
## Layout
|
|
|
|
- `api/` - FastAPI service, core calculations, service orchestration, tests.
|
|
- `scripts/` - data bootstrap/import entry points.
|
|
- `data/` - mounted data volume for DEM, landcover, and canopy rasters.
|
|
- `docker-compose.yml` - local stack with API, worker, Redis, PostGIS, optional tiler.
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
cp .env.example .env
|
|
docker compose up --build api redis postgis
|
|
```
|
|
|
|
The API is served at `http://localhost:8000`, with OpenAPI docs at `/docs`.
|
|
|
|
## DEM Bootstrap
|
|
|
|
Download Copernicus DEM GLO-30 COG tiles for Saint Petersburg and Leningrad Oblast:
|
|
|
|
```bash
|
|
python scripts/bootstrap_dem.py --bbox 27.3,58.4,35.8,61.4 --output-dir data/dem
|
|
docker compose restart api worker
|
|
```
|
|
|
|
The API samples all `.tif`/`.tiff` files under `DEM_PATH` recursively. In Docker,
|
|
the default `DEM_PATH=/data/dem` points to the mounted `./data/dem` directory.
|
|
|
|
For local Python development:
|
|
|
|
```bash
|
|
cd api
|
|
python -m venv .venv
|
|
source .venv/bin/activate
|
|
pip install -e ".[dev]"
|
|
python -m pytest
|
|
python -m ruff check .
|
|
```
