About the dataset

The data is sourced from http://www.vdstech.com/world-data.aspx and converted with http://ogre.adc4gis.com/.
There are 37,372 cities with defined Polygon boundaries with the precision of 5 decimal points (about 1 meter), although accuracy of the data (how well the polygons define the real-world city boundaries) varies greately.
Each polygon is only identifiable by city NAME, from no particular standard. There are many cities with the same name. (eg there are 11 SPRINGFIELDs and 2 MOSCOWs), either due to duplication or because they are located in different counties/states.
Cities with NAME = null were removed by @ilyankou.
