USING THE GPS GRID Superimposed on this map is a grid representing minutes This places us north of the 30º 56' parallel, and west of the of latitude and longitude. Map users with a global 98º 28' meridian. The numbers to the right of the decimal positioning system (GPS) receiver can use this grid to point on our GPS unit represent decimal minutes. For 16 determine their position. Lines of longitude are labeled latitude, a decimal minute reading of 0.5 tells us we are with negative numbers to indicate their position west of halfway between the 30º 56' parallel and the 30º 57'. (See Central Texas the Prime Meridian of 0º that runs through Greenwich, dashed line approximating position.) In the case of 800 15 Highland Lakes England. longitude, the decimal minute value of 0.25 indicates we are approximately one-fourth of the distance between the 2545 14 To locate a position on the map using a GPS receiver, first Lake 98º 28' meridian and the 98º 29'.
