Figure 1 (Declination Diagram) Declination Conversion of Grid and Magnetic Azimuths Utilizing the Declination Diagram A magnetic compass gives a magnetic azimuth, but in order to plot this line on a gridded map, the magnetic azimuth value is changed to grid azimuth. The opposite process is done for converting a grid azimuth to a magnetic azimuth.

A declination diagram is '…a diagram that shows the angular relationship, represented by prongs, among grid, magnetic, and true norths…Notice that the true, magnetic, and grid north reference lines are marked at the top with a star, the letters "MN" and an arrow, and the letters "GN", respectively', as shown in figure 1 (taken ...

On our example map, your finger must move to the left as it transitions from the magnetic to the grid north arrows in the declination diagram, therefore using the mnemonic LARS tells us to add the 13-degree declination to our magnetic azimuth to get our grid azimuth of 283 degrees. Above: Acadia National Park, Maine.

Using the delineated map index, find the map or maps you want based upon the location of the nearest city. With this information, order maps using the following forms: (1) Standard Form 344. It can be typed or ...

Declination Diagram. The declination diagram is located in the lower margin of large-scale maps and indicates the angular relationships of true north, grid north, and magnetic north. On maps at 1:250,000 scale, this information is expressed as a note in the lower margin.

Military maps are typically Grid North up. ... Your Declination and Grid Variance Diagram. To understand how bearings using different north references are related it helps to draw an additional line onto the declination diagram representing the bearing to the target. On this diagram it's labeled "Tgt."

Adding a declination diagram in arcmap

A diagram at the bottom of most USGS topographic maps shows three north arrows--true north, grid north, and magnetic north--and the angles between them. Some maps, especially very old maps, do not have this diagram. True north, also called geodetic north or geographic north, is the direction of the line of longitude that bisects the quadrangle.

Declination Diagrams. The means that appears on USGS maps is called the declination diagram.The word declination means "difference in direction," such as the difference in direction between true north and magnetic north. If the map also includes directions relative to a military grid, then grid north will also appear in the declination diagram.
