Experiment with Cosmogony for OSM data extraction and improved region hierarchy

OhmSpectator commented 9 months ago

Description

We are exploring the use of Cosmogony, a tool for extracting region hierarchy data from OpenStreetMap (OSM). This initiative is driven by the need for more accurate and up-to-date geographic data, as our current data source (GADM) has significant limitations. Cosmogony offers a dynamic way to generate region data directly from OSM.

Requirements

[ ] Perform a trial run of the Cosmogony tool to extract region hierarchy data. This will help us understand the process and the quality of data it can provide.
[ ] Assess the memory requirements for running Cosmogony, as its documentation indicates high RAM usage.
[ ] Evaluate the integration potential of Cosmogony's output with our current system.
[ ] Develop a strategy for regularly updating our data using Cosmogony, ensuring scalability and performance are maintained.
[ ] Update project documentation to include details of the Cosmogony integration and its operational requirements.

Additional Information

Cosmogony not only provides a method to extract updated geographic data but also poses challenges in terms of resource requirements, particularly RAM. A careful evaluation of these aspects is crucial to successfully implement and benefit from this tool.

There is also https://www.geofabrik.de/data/admin-polygons.html that provides Adm Polygons for cost. Check it.

I've created a cosmogony.json file for Africa, but I failed to explore it with the suggested tool: https://github.com/osm-without-borders/cosmogony_explorer/issues/60
