2. Geographer’s Basics Title – usually tells what the map is about Compass Rose – symbol that gives the directions of North, South, East, and West. Legend – (notice all symbols, colors, etc) Lines of Latitude and Longitude Scale

3. More on Scale Scale refers to the how much area is shown on a map Small Scale means a large amount of area is shown with very little detail, Example – A map of the whole world. Large Scale means a small amount of area is shown. Ex.- a street map of downtown Houston, shows all of the streets. This map is only helpful if you are traveling in downtown Houston.

5. Globe, is a type of Map Advantages: Directions—True Distances—True Shapes—True Areas—True Disadvantages: Even the largest globe has a very small scale* and shows relatively little detail. Costly to reproduce and update. Difficult to carry around. Bulky to store.

6. Map Projections Map projections are representations of a curved earth on a flat map surface. The three basic types of map projections are azimuthal, conical, and cylindrical. With azimuthal & conical you generally can only show parts of the earth such as one or two continents. With a cylindrical projection you can show the whole earth but with some distortions.

7. “Types of Maps” Four main types (not projections). Physical – Shows landforms/bodies of water or physical features. Political – Shows features humans created, such as cities, territories, or countries. The borders are usually shown. Thematic – usually has a specific theme, location of oil and natural gas deposits in the world Flow Line – illustrate movement of people, goods, ideas, animals, etc…

8. Thematic Maps Qualitative: –Use colors or patterns to show a specific idea Cartograms: –Use size to show a specific idea – size of countries is not true to actual size, but represents specific data Flow-line maps: –Illustrate movement, usually shown in a series of arrows

9. Absolute and Relative Location Absolute Location- the exact place on earth where a geographic feature is foundAbsolute Location- the exact place on earth where a geographic feature is found Uses Latitude and Longitude, specific, exact directionsUses Latitude and Longitude, specific, exact directions Relative Location- describes a place in relation to other places around it.Relative Location- describes a place in relation to other places around it.
