Elements of a Map
In the TODALSIGS or DOGSTAILS acronyms, this fundamental element helps readers determine direction using cardinal points like North, South, East, and West.
Orientation (Look for the compass rose!)
This type of map focuses on showing boundaries, cities, states, or national capitals rather than physical elevation.
Political map
Commonly used in geography textbooks, this compromise projection shows nearly true continental sizes and shapes, though landforms near the poles appear somewhat flattened.
Robinson Projection
This vast body of water is the world's largest and deepest ocean, covering more area than all of Earth's landmasses combined.
Pacific Ocean
Stating that Cairo, Egypt, is located at approximately 30°N latitude and 31°E longitude is an example of this specific type of location.
Absolute Location
This element shows the ratio of length on a map compared to actual ground distance on Earth, often displayed as a bar or representative fraction.
SCALE
This specific thematic map uses different color shading and intensity across predefined regions to display statistical data like median income or election results.
Choropleth Map
This cylindrical projection maintains correct direction for navigation, but severely inflates landmass sizes near the poles, making Greenland look as large as South America.
Mercator Projection
This is the smallest continent by land area, made up entirely of a single island nation and surrounding Pacific island groups.
Australia & Oceania
This theme of geography describes a location's unique physical and human characteristics, such as climate, terrain, architecture, and local culture.
Place
This map element acts as a key, explaining the specific meanings of symbols, shading, and colors used throughout the map.
Legend or Key
This type of map uses contour lines to represent physical elevation, slopes, terrain gradients, and valleys.
Topographic Map
Constructed by wrapping a cone around the globe, this projection type shows shape fairly accurately and is ideal for east-to-west landmasses like the United States.
Conical projection
Home to over 4.7 billion people, this continent is the largest both in physical land area and total human population.
Asia
Building dams for flood control, terracing mountainsides for farming, or wearing heavy coats in winter are all examples of this geographical theme.
HEI
The acronym TODALS outlines mandatory map components. The "A", "L", and "S" stand for Author, Legend, and Scale. The "T", "O", and "D" stand for these three elements.
Title, Orientation, Date
Maps showing the Bantu migrations across Africa or global trade routes use arrows and lines to show movement. They are known by this term.
Flow-line Map
Also known as an "interrupted map," this compromise projection divides the oceans to keep the shapes and sizes of landmasses accurate, though map distances become incorrect.
Homolosine projection
This body of water is the second-largest ocean on Earth, separating North and South America from Europe and Africa.
Atlantic Ocean
This theme examines how people, goods, trade, ideas, and information travel across the globe.
Movement
This advanced spatial tool combines data from multiple digital sources into layered maps to solve real-world problems. This serves as a digital data base.
GIS (Geographic Information System)
This specialized type of map intentionally distorts or scales the physical size of geographic areas to reflect a specific variable, such as total population or organic agriculture acreage.
Cartogram
This projection is made by touching a flat plane to a single point on a globe. Its main disadvantage is that distortion increases rapidly as you move away from that center point, making it poor for showing the entire world at once.
Planar (Azimuthal) Projection
Surrounding the southernmost landmass on Earth, this ocean was officially recognized by the International Hydrographic Organization in 2000 as extending from the coast of Antarctica north to latitude 60°S.
Southern Ocean
The "Corn Belt" in the U.S. Midwest or the "Middle East" are examples of this theme, which groups different places together based on shared physical, cultural, or economic characteristics.
