How close does a 8 digit grid coordinate get you? 10 meters Remember, four-digit grids get you to within 1000 meters, six-digit grids to within 100 meters and an eight-digit grid gets us to within 10 meters. For example, say you have a line of latitude at 15°N, 24 minutes, and 15 seconds. You have a line of longitude at 30°E, 10 minutes It is common practice under certain situations not to specify the first two components of the MGRS coordinate string. For example, if all users who are exchanging MGRS coordinates are working within the same grid zone designation or 100,000-meter square, it is not necessary to specify these components, because all participating users know they are all working within the same area. The confusion comes in when soldiers try to use a map to get a 10-digit grid coordinate, which equates to a 1 meter precision. A 1:50,000 scale map is only accurate to 50m 90% of the time so a 6 digit (100m precision) or an 8 digit (10m precision) are more appropriate. An example of an MGRS coordinate, or grid reference, would be Use the Menu button to toggle the USNG coordinates grid on/off. While the map is open you can now display data from *any* public-facing (i.e. no login required) ArcGIS server along with a USNG grid on top of that data. To get started, click the basemap button (next to the 'Menu' button) then under the 'Overlay' heading, click "Add GIS overlays". This allows you to get a grid reference while you're recording an activity - for example during a Run or Walk. For example, to add the data field on my Fenix 3 I have to start an activity - e. g. "Run" , then press the menu button, go to Settings - Current App - Data Screens and I can add the Grid Ref field from the "ConnectIQ" section. To format your coordinates so they work in Google Maps, use decimal degrees in the following format: Correct: 41.40338, 2.17403; Incorrect: 41,40338, 2,17403; Tips: List your latitude coordinates before longitude coordinates. Check that the first number in your latitude coordinate is between -90 and 90. .
