Benchmark Road & Recreation Atlas Ruler Set

The Benchmark Road & Recreation Atlases are designed to be used with these ruler sets. They contain ruler pairs for measuring latitude and longitude coordinates at latitudes found in their respective state on a map with a scale specific to that state's atlas. These rulers also contain rulers for measuring statute miles and kilometers.

The "landscape" pages of the atlas have a printed latitude/longitude grid shown with thin black lines, with the values marked just inside the edges of the map in a degrees, minutes, and seconds format. The "recreation" and "regional" sections of the atlas, however, do not have latitude/longitude markings and are printed with a different scale, making these rulers unsuitable for use in those sections.

It is important to note that longitude rulers used north of their design parallel of latitude will be too long to fit the grid. The ruler should be "close enough" up to about 1° north of the design latitude. As you move further north, you may find that the next ruler in the set is a closer fit. Alternatively, you can use the ruler on a slight diagonal between the grid lines to compensate for the extra length.

These rulers are printed on a 10 mil. waterproof polyester stock and come packaged in a vinyl pouch with an instruction sheet printed on Rite-In-The-Rain paper.
