The latitude longitude coordinate system uses angular measurements to describe a position on the surface of the earth. The system has been in use, with little change, since the astronomer …

Because the lines of longitude converge at the poles, a degree of longitude represents a varying distance on the ground, depending on the latitude. Place the ruler so that it spans the lines of …

The point of interest is located where the plotted lines of latitude and longitude cross. If plotting longitude seems tedious, check out our new Custom MapRulers, with a longitude scale …

Positive values of latitude are north of the equator, negative values to the south. Watch the sign on the longitude, most programs use negative values for west longitude, but a few are opposite.

Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south.

Tools for both UTM/MGRS/USNG and Latitude/Longitude coordinates are available. If you are already an experienced map and GPS user, you have come to the right place to get …

In angular coordinate systems like latitude and longitude, the distance covered by a degree of longitude differs as you move towards the poles and only equals the distance covered by a …

If you are working with maps that cover more than 6 degrees of longitude or are 1:1,000,000 scale or less, you will probably want to use lat/lon coordinates. Small scale maps are often projected …

With the advent of inexpensive GPS receivers, many other map users are adopting the UTM grid system for coordinates that are simpler to use than latitude and longitude.
