noise-map

CLI tool to query noise levels for any German address from the UBA Lärmkartierung (German Federal Environment Agency noise map).

Returns day (Lden) and night (Lnight) noise levels across road, rail, air, and industrial sources.

Web UI

No install needed — use the web version at https://wusche1.github.io/noise-map-api/

Supports single address lookups and CSV batch processing directly in the browser.

CLI

Prerequisites

• Python 3.9+
• Poetry

Setup

poetry install

Usage

Single address

python -m noise_map.cli "Alexanderplatz 1, Berlin"

Found: Berolinahaus, 1, Alexanderplatz, Mitte, Berlin, 10178, Deutschland
Coordinates: 52.521506, 13.412381

Source                                Day           Night
---------------------------------------------------------
Road (major roads)            55-59 dB(A)               -
Road (urban)                  55-59 dB(A)               -
Rail (major lines)            60-64 dB(A)     50-54 dB(A)
Rail (urban)                  60-64 dB(A)     50-54 dB(A)
Air (major airports)                    -               -
Air (urban)                             -               -
Industry (urban)                        -               -

Batch processing (CSV)

Prepare a CSV with an address column (semicolon-separated):

address
Alexanderplatz 1, Berlin
Hauptbahnhof, München

Then run:

python -m noise_map.cli --batch input.csv output.csv

If the address column has a different name:

python -m noise_map.cli --batch input.csv output.csv --col Adresse

Output is a semicolon-separated CSV (opens directly in German Excel) with all noise levels. Processes ~1 address/second due to geocoding rate limits.

Tests

How it works

1. Geocodes the address to coordinates using OpenStreetMap/Nominatim
2. Reprojects to EPSG:3857 (Web Mercator)
3. Queries the UBA ArcGIS MapServer REST API for all noise layers in parallel
4. Returns the noise level classification per source (road, rail, air, industry — day & night)
