UTM Grid Zone 11
The USNG grid squares nearly always have more than 5 points. ( a square polygon has a minimum of 5 points, since the end must finish at the start) Many of the squares have 10 or 12 points, and they seem to be unecessary. So, this dataset is simiplified with the polygons limited to 5 points. This simplification results in the same number of dataset rows, but reduces the file size by about 42%.
