Abstract

Map users must refer to an appropriate scale in interpreting wildland resource maps. Length and area equivalents for nine map scales commonly used have been computed. For each scale a 1-page table consists of map-to-ground equivalents, buffer strip or road widths, and cell dimensions required for a specified acreage. The conversion factors are stored in a Fortran program. It can be easily modified to compute equivalents for other map scales.

Keywords

map, map scale (ratios), map interpretation, map-to-ground equivalents
