Truncated position formats for less precise positions I would encourage you to use spaces when writing USNG coordinate strings,Īnd to pause briefly between logical parts when communicating USNG coordinate strings verbally. The understanding and communication of coordinate strings between humans. The inclusion of spaces to separate the logical parts of the coordinate string has been shown to facilitate The USNG standard states that 'A USNG reference is formally written as an entity without spaces, parentheses,ĭashes, or decimal points.' I have not strictly followed this part of the standard in these tutorials. The last 3 digits are the distance in meters measured from the southern grid line. Using a map with a 1000m grid, the first two digits are come from the large type on the label for the grid line to the south of the position. Measurement of North-South position, within the 100,000 meter square, in meters. The bottom set of numbers, 44683, represent a The last 3 digits are the distance in meters measured from the western grid line. Using a map with a 1000m grid, the first two digits are come from the large type on the label for the grid line to the west of the position. Measurement of East-West position, within the 100,000 meter square, in meters.

The top set of numbers, 06832, represent a

It identifies a unique 100,000m square within the Grid Zone. Necessary to make the coordinates unique over the entire globe. The 10S is the Grid Zone Designation you are in. The two grid lines are 1000 meters apart. , reads 'seven hundred and six thousand meters East.' The label, Look along the bottom edge of the map at the labels for the vertical grid lines. The vertical grid lines determine East-West position and the horizontal grid lines determine North-South Larger type numbers are replaced by the 100,000m Square ID. When using USNG or MGRS the small type numbers to the left of the The grid is labeled with UTM coordinate values.īut the same grid is used for both USNG and MGRS positions. The map has grid lines spaced every kilometer or 1000 meters. Set to display position in US National Grid format, would report a location of: Let's look at where the various parts of the USNG position come from on the map. Standing at the center of the marker shown on the map below, a GPS unit
