I have data from the national storm prediction center that is marked with values of : elat slat elon slon
`slat slon elat elon `31.6671 -90.9352 31.6998 -90.8813
What do those values mean?
What does the "s" & "e" prefix stand for?
Oh, I think I finally figured out what those values are.
The data is tornado data and I believe the slat, slon are Start locations (of the tornado) and the elat, elon are End locations for the tornado.
This only became apparent when I added those locations to a Google map and saw the distances.
Here is a map with the two locations on it (obviously the path is a driving path and not path of tornado, but it shows the distance).
