What do yellow colors on a map signify?

Yellow colors on a map signify built-up areas, particularly urban developments or agricultural land. This coloration is used to denote areas that have been significantly altered by human activity, whether through construction, farming, or infrastructure development. It highlights regions where there are structures, roads, and other features indicative of human habitation or industrial activities, distinguishing them from natural landscapes.

In contrast, water bodies are typically represented by shades of blue, while forests are indicated using green shades on maps. Military installations often have unique symbols or colors that do not necessarily align with the typical color-coding for built-up areas or natural features. Understanding these color conventions is essential for effective map reading and navigation, particularly in military contexts where distinguishing between various terrains can be crucial.
