| What are the basic colors of a map, and what does each color represent? |
|
Definition
Black - Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels. Red-Brown - The colors red and brown are combined to identify cultural features, all relief features, non-surveyed spot elevations, and elevation, such as contour lines on red-light readable maps. Blue - Identifies hydrography or water features such as lakes, swamps, rivers, and drainage. Green - Identifies vegetation with military significance, such as woods, orchards, and vineyards. Brown - Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on red-light readable maps. Red - Classifies cultural features, such as populated areas, main roads, and boundaries, on older maps. Other - Occasionally other colors may be used to show special information. These are indicated in the marginal information as a rule. |
