| 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 |
