FAO GAUL: Global Administrative Unit Layers 2015, First-Level Administrative Units

AI-generated Key Takeaways

• The Global Administrative Unit Layers (GAUL) dataset provides standardized information on administrative units globally.

• The dataset includes global layers with a unified coding system at country, first, and second administrative levels, and sometimes lower levels where data is available.

• The methodology involves collecting data from reliable sources, validating features, adding data to a global layer based on UN country boundaries, and generating unique codes.

• The dataset is distributed for non-commercial use to authorized institutions and agencies under specific license conditions.

Description

The Global Administrative Unit Layers (GAUL) compiles and disseminates the best available information on administrative units for all the countries in the world, providing a contribution to the standardization of the spatial dataset representing administrative units. The GAUL always maintains global layers with a unified coding system at country, first (e.g. departments), and second administrative levels (e.g. districts). Where data is available, it provides layers on a country by country basis down to third, fourth, and lowers levels. The overall methodology consists in a) collecting the best available data from most reliable sources, b) establishing validation periods of the geographic features (when possible), c) adding selected data to the global layer based on the last country boundaries map provided by the UN Cartographic Unit (UNCS), d) generating codes using GAUL Coding System, and e) distribute data to the users (see Technical Aspects of the GAUL Distribution Set. Note that some administrative units are multipolygon features.
