资源简介：
The Significant Administrative Units (SAU) Dataset is a geo-coded, time-variant dataset of administrative units around the world between 1945 and 2018. SAU version 2.0 provides geo-coded polygons for all first-order administrative units that existed in 180 countries at any point between 1945 and 2018. In addition, for the same sample, it also provides geo-coded polygons for lower-level administrative units that are constitutionally recognized as autonomous and for constitutionally-recognized "special" regions. In total, it contains 8397 geocoded polygons, each of which represents a specific unit in a time period between 1988 and 2018.
