Experiment with Cosmogony for OSM data extraction and improved region hierarchy

[OhmSpectator]

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.

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