I'm somewhat ashamed I don't know the answer to this seemingly easy question, and I'm sure I have completely over-thunk it.
Your assistance is appreciated...
Okay, so I installed a new weather station on our property. The console set up wants a latitude and longitude for the sensor locations. Easy enough,
right? So I get out my GPS and get the coordinates. The values are a positive North latitude and a negative value for East longitude. Fine, I'm
used to this, we're in North America. HOWEVER...the weather station will not accept a negative value for an Easting. It want's instead a value for
a West longitude.
Now at first I thought this would be as simple as subtracting my negative East value from 360 degrees, but this results in a value of greater than
180. The weather station will only take values from 0 - 180. Okay, that makes 'some' sense (180 degrees being one half of a circle), BUT...
I can't figure out how to calculate my "West" longitude value within these constraints (i.e. a value between 0 and 180).
My Easting value is -140....so what's the Westing value???
Feel realy dumb for asking this question, but thanks for your responses (in advance).
