This document provides an overview of key map skills, including compass directions, scale, grid references, contour lines, symbols, and measuring distance. It explains that a map shows features of a place and uses lines of longitude and latitude to form a grid reference system. Contour lines are used to represent height or elevation since maps cannot display three-dimensional terrain. Symbols simplify features and a map scale allows measurement of real-world distances based on the scale ratio. Measuring distance involves using a scale to determine real-world lengths between two points on a map.
