What does slat and elat (slon, elon) in latitude and longitude values mean? 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" &amp; "e" prefix stand for?
This might be product specific, but if it's anything like my MODIS experience this refers to start and end latitude and longitude. Are you looking at a small region on the Mississippi/Louisiana border?
