Product Description
This ruler is designed to measure slope on a 1:24,000 scale topographic map. Slope is determined by comparing the distance between contour lines with the samples on the edge of the ruler.
The front side of the ruler is designed to measure percent slope for maps with a 10, 20 or 40 foot contour interval.
The back side of the ruler measures slope in degrees for maps with a 20 or 40 foot contour interval. The back side also indicates slab avalanche frequency for the various slopes on the 40 foot contour interval map.
If you need to physically measure a slope angle, check out our Reference Card -- Inclinometer for Slope Angle in Degrees and Percent.
The ruler is printed on a sturdy 20 mil white plastic stock for durability.
