Automated edits/adding school levels

Goal

Our motivation is to unify and complete tagging for schools.

We want to improve tagging so that you can run reliable data processing/analysis with OSM.

Implementation

The process will perform the following steps:

1. Get a dataset of all schools without the isced:level=*. We use Overpass API for this. Save it as *.osm file.
2. We let a python script change the osm file:
   • The following repository contains the script, an example input dataset and an example output file: https://github.com/EmnaBH/adding-isced-level-to-schools-in-germany
   • The osm file is read in as xml.
   • The script goes through each object (node/way) and reads the name.
   • If the name contains a certain string (e.g. grundsch or grund-) (primary schools), the corresponding isced:level is inserted into a list.
   • The list is converted into a string and a key-value pair is created for the objects.
   • At the end the file is saved as output.osm.
3. The output can be uploaded to osm and the changes can be seen after a short amount of time.
