GADM version 3.6 supports several standard formats for use in software like ArcGIS, QGIS, and R: GeoPackage (.gpkg) : The standard format for most modern GIS applications. Shapefile (.shp)

: A widely compatible format for legacy and current GIS software. : Specialized files for use with R spatial data objects. KMZ (.kmz) : Suitable for viewing boundaries in Google Earth. License and Usage Global Administrative Areas - Atlas

4.2 Converting to Other Projections

GADM 3.6 works in WGS84, but for area calculation or European mapping, reproject:

gdf_mercator = gdf.to_crs("EPSG:3857")  # Web Mercator
gdf_utm = gdf.to_crs("EPSG:32631")      # UTM zone 31N

Part 3: Key Features of Version 3.6

When working with v3.6, be aware of its specific characteristics compared to newer versions (like v4.x):

  1. Administrative Levels: Version 3.6 generally supports up to 5 levels of administrative subdivision for some countries, though the global dataset typically standardizes levels 0 through 2.
  2. Coding System: This version uses the GADM ID system unique to their database. If you need ISO standard codes (ISO 3166-1 alpha-3), ensure they are present in the attribute table under columns like GID_0 or ISO (depending on the specific file iteration).
  3. Topology: v3.6 is known for having "cleaned" topology compared to earlier versions (e.g., v2.8), meaning fewer sliver polygons and gaps between borders.

Step 2 – Select your format

GADM 3.6 offers five formats. Choose based on your workflow:

| Format | Best for | Notes | |--------|----------|-------| | Geopackage | QGIS, modern GIS | Recommended – single file, no shapefile size limits | | Shapefile | ArcGIS, legacy tools | Requires multiple files (.shp, .shx, .dbf) | | KML | Google Earth, web maps | Lightweight, limited attributes | | R (sp) | R users (old workflow) | Direct load() into R’s sp package | | R (sf) | R users (modern) | sf object ready |
