The decimal part of dcSystemLatitude contains up to 7digits. This number is in 1/1000000 degree fractions or 0,0000001 degree. A part of the systems global positioning data. Lines of Latitude has a range of +-90 degrees and are the imaginary horizontal lines shown running east-to-west (or west to east).

Longitude lines are imaginary lines running from the north pole to the south pole. Longitudes are usually (WGS84) referenced from Greenwich, England where it has been established as Zero Degrees longitude. Latitude and Longitude together with the Elevation can be used for automagically placing system icons on NMS/Sitemonitors system that support this.
