The longitude and latitude coordinates will be updated when the GPS picks up satellite
signals. “W/E” means west/east hemisphere; “N/S” means north/south hemisphere; “d” means
degree; “m” means minute; and “s” means second.
If for any reason your GPS can’t pick up a signal you can manually enter the GPS
coordinates. Press or key to move the cursor and using or key to toggle between
“W” and “E”, “N” and “S”, or to change the numbers. It is always a good idea to do your home
work to get the GPS coordinates before traveling to a new observation site.
The site coordinates information can be found from internet, such as GPSVisualizer
(http://www.gpsvisualizer.com/geocode
), by entering the city name or address. In case you only
find the site information in decimal format you can convert them into d:m:s format by multiplying
the decimal numbers by 60. For example, N47.53 can be changed to N47º31'48”: 47.53º = 47º
+0.53º, 0.53º=0.53x60'=31.8', 0.8'=0.8x60"=48". Therefore, 47.53º=47º31'48" or 47d31m48s.
Same as N47º31.8’: 31.8’=31’+0.8’, 0.8’=0.8x60”=48”.
