Types of Maps

These flashcards cover key terms and concepts related to types of maps, their symbols, scales, and the methods used to interpret them.

Topographic Map

A map that uses contour lines and symbols to represent the terrain and elevations, typically showing 20 m intervals.

Orthographic Map

A type of map that can be in black, white, or color, employs 5 m intervals and includes selected symbols, operating at a larger scale (1:10,000) for more detail.

Conventional Symbols

Symbols used on maps to represent specific features, which may be presented in a key; includes symbols for water, vegetation, and man-made features.

Scale

A ratio that indicates the relationship between distance on the map and actual distance on the ground; a smaller scale covers a larger area with less detail.

Direction Abbreviations

The abbreviated forms for cardinal and ordinal directions, including N (North), S (South), E (East), W (West) and their combinations like NE (Northeast).

Distance Calculation on Maps

A method to determine actual distance by measuring the length between points on the map and converting it using scale factors, e.g., 1 cm on a topographic map equals 500 m.
