1) analyze the signifinace of various colors used in toposheets
Answers
Answer:
They help to distinguish between different feature types. You can make a topographic map with just black lines, but it’s difficult to read and interpret.
By convention, the commonly used colours on Australian topographic maps are:
Red (or red/brown) for cultural detail such as roads and built-up areas;
Black for type and other cultural details such as railway lines, fences and individual buildings;
Brown for contours;
Blue for hydrographic detail such as rivers, lakes and oceans; and
Green for vegetation.
These are not universal, however. For example, the British and Swiss mapping agencies use other colours, or at least use these colours slightly differently.
