While that does indeed work, I'd guess the OP was not clear
in their intentions. For longitude, you would want to leave the
0 to 180 range as is, and change the -180 to 0 data to fall in the
range 180 to 360 by adding 360 to it.

i.e. -1 should become 359.

One can add 360 to longitude and "not change anything " since
they are degrees.

Cheers,
