Quickstart — your first extraction

From zero to a map of coverage in about two minutes. No API key needed for Google.

1. Install

pip install tracelines

2. Find the nearest blue line to a point

tracelines nearest 44.435072 26.050430

You'll get the nearest official car panorama — its id, capture date, distance, and a link that opens it in Street View. It is never a photosphere.

3. Extract an area to GeoJSON

tracelines extract --bbox 26.09,44.45,26.11,44.46 --sources google --out coverage.geojson

--bbox is west,south,east,north. Or use a named area:

tracelines extract --area bucharest-city --sources google --out bucharest.geojson

Add --precision for pure car coverage (drops trekker/indoor; slower).

4. Look at it

Open the live GUI and drag your coverage.geojson onto the map. Toggle sources, color by capture year, click a line to inspect it, or click the map in Nearest mode to find the closest pano.

Prefer no install? The GUI's "Full Bucharest" button shows a whole city with zero setup.
