In operation maps, there can also be scales of 1:10,000 and 1:500. Convert Coordinates - Calculate a position in a variety. Tactical military scales are usually 1:50,000 and 1:1000,0000. Coordinate Grids Polygon Area Convert Coordinates Batch Convert.
Romer readers can be used to find the exact USNG coordinates to describe any place in a uniform, standardized manner. For example, 1/50,000 or “2cm equals 1 km” respectively. Use USNG hard-copy maps or online maps that enable coordinates to be described exactly. Note: Modern maps may display the scale as a fraction or a statement on the top of the map. It is shown as both a ratio and a scale bar at the bottom of the map, typically. Scale is the ratio between the distance on the map and the same distance on the ground. These three parts together, give us the full grid reference.
By clicking on the desired location, the 6-figure Grid reference will be. In this example, the identification is NS.įor the grid zone designator, make the prefix when reporting outside the grid zone designator.
