Comprehensive Global Administrative Zones - ADM2 Municipalities

078dea69…Usage notes
For country-level (ADM0) and district-level (ADM1) boundaries, see geoBoundaries Comprehensive Global Administrative Zones Countries and Districts datasets. Boundaries are terrestrial, so exclude maritime boundaries and exclusive economic zones. Disputed areas have been removed and replaced with standard polygons following the US Department of State definitions. Boundaries are validated by automated scripts and a minimum of two independent practitioners, but may differ from other datasets, particularly in disputed regions. See GitHub repository for a list of known issues.
Variables
geometry
Description
Boundary geometry.
Usage notes
Geometries are simplified relative to individual country files available from geoBoundaries directly.
shape_group
Description
Three character ISO-3166 code for the country or territory the boundary belongs to.
Usage notes
Shape groups link directly to shape group variable from the geoBoundaries Comprehensive Global Administrative Zones ADM0 Countries dataset. For disputed territories, ISO-3166 codes are replaced by a unique number.

Description
Boundary unique identifier.
shape_name
Description
Boundary name.
shape_type

ADM2 indicates municipality-level detail, relative to the country-level (ADM0) and district-level (ADM1) detail of other geoBoundaries Comprehensive Global Administrative Zones datasets. ADM1 indicates district-level detail for territories without ADM2 sub-boundaries. ADM0 indicates country-level detail for territories without ADM1 sub-boundaries (Antarctica, Vatican City).
