Features

  • Export geographic data from Overture Maps.
  • Upload data to HDX.
  • Support for multiple output formats.
  • Configurable via YAML and environment variables.
  • Logging setup using environment variables or parameters.

Installation

pip install overture2hdx

Configuration

The application is configured using a YAML file and environment variables.

Example config.yaml:

iso3: npl
geom: '{"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"coordinates": [[]], "type": "Polygon"}}]}'
key: osgeonepal_pkr
subnational: true
frequency: yearly
