Description
Geodata data package providing geojson polygons for all the world's countries. Perfect for use in apps and visualizations.
Data
The data comes from Natural Earth, a community effort to make visually pleasing, well-crafted maps with cartography or GIS software at small scale.
More info about countries can be obtained from datapackage https://github.com/datasets/country-codes by a join on field ISO3166-1-Alpha-3
Preparation
To run the script and update the data:
Prerequisites
-
Install required tools:
- GDAL - for geographic data processing
-
Verify GDAL installation:
ogr2ogr --version
Data Processing
The project uses ogr2ogr to convert Natural Earth's country boundaries from Shapefile to GeoJSON format, with the following features:
- Coordinate precision set to 6 decimal places
- Geometry validation enabled (
-makevalid):- Fixes self-intersecting polygons
- Corrects ring orientation
- Removes duplicate vertices
- Ensures geometric validity for better compatibility with GIS tools
- Selected fields:
name: Common name of the country (from admin field)ISO3166-1-Alpha-2: Two-letter ISO country code (from iso_a2 field)ISO3166-1-Alpha-3: Three-letter ISO country code (from iso_a3 field)
To process the data:
make data
This will:
- Download the Natural Earth countries dataset
- Convert it to GeoJSON format with the specified settings
- Save the result in
data/countries.geojson
