a-In modern mapping, a topographic map or topographic chart is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.

b-Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.

c-Political maps often use four or more colors to represent different countries or internal divisions of countries, such as states or provinces. Blue often represents water and black and/or red is frequently used for cities, roads, and railways

d-An opisometer, also called a curvimeter, meilograph, or map measurer, is an instrument for measuring the lengths of arbitrary curved lines. A simple opisometer consists of a toothed wheel of known circumference on a handle. The wheel is placed in contact with the curved line to be measured and run along its length
