High resolution, World Bank-approved administrative boundaries. Includes Admin 0, 1, 2, Non-Determined Legal Status Areas (NDLSA), and an ocean mask. An Admin 0 line file (for visualization purposes with World Bank-specific drawing instructions) can also be found. A data dictionary and additional columns of information which can be joined to the Admin 1 and 2 files are available as separate downloads. To report an error in any of the admin boundary files, please raise a new issue here: https://github.com/worldbank/WB_GAD/issues and it will be considered during the next update cycle.
