4u'''I{Karney}'s Universal Polar Stereographic (UPS) projection. 

5 

6Classes L{Ups} and L{UPSError} and functions L{parseUPS5}, L{toUps8} and L{upsZoneBand5}. 

7 

8A pure Python implementation, partially transcoded from I{Karney}'s C++ class U{PolarStereographic 

9<https://GeographicLib.SourceForge.io/C++/doc/classGeographicLib_1_1PolarStereographic.html>}. 

10 

11The U{UPS<https://WikiPedia.org/wiki/Universal_polar_stereographic_coordinate_system>} system is used 

12in conjuction with U{UTM<https://WikiPedia.org/wiki/Universal_Transverse_Mercator_coordinate_system>} 

13for locations on the polar regions of the earth. UPS covers areas south of 79.5°S and north of 83.5°N, 

14slightly overlapping the UTM range from 80°S to 84°N by 30' at each end. 

15 

16Env variable C{PYGEODESY_UPS_POLES} determines the UPS zones I{at} latitude 90°S and 90°N. By default, 

17the encoding follows I{Karney}'s and U{Appendix B-3 of DMA TM8358.1<https://Web.Archive.org/web/ 

1820161226192038/http://earth-info.nga.mil/GandG/publications/tm8358.1/pdf/TM8358_1.pdf>}, using only 

19zones C{'B'} respectively C{'Z'} and digraph C{'AN'}. If C{PYGEODESY_UPS_POLES} is set to anything 

20other than C{"std"}, zones C{'A'} and C{'Y'} are used for negative, west longitudes I{at} latitude 

2190°S respectively 90°N (for backward compatibility).
