The Nominatim Data Analyser is a QA tool used to scan the nominatim database and extract suspect data from it. These data are then presented to mappers through this webapp developed in Svelte. The repository of the main backend can be found here: Nominatim-Data-Analyser.
By default, the frontend will load its data from the official
Nominatim QA service at https://qa-tile.nominatim.openstreetmap.org.
If you want to use your own data, set the environment variable
NOMINATIM_QA_WEBPATH to the URL of the QA service.
Building requires yarn2. If your system only ships with classic yarn (as with current Debian/Ubuntu distros), enable yarn2 by running the following commands from the root folder:
yarn set version berry
yarn set version stable
To build the app go into the root folder and run:
yarn install
This will install all the dependencies required by the app and then run:
yarn build
Then you need to serve the public/ folder with any webserver to access the app.
