1 CH1, S2: The Geographer’s Tools *Eratosthenes- earliest geographer to calculate the circumference on the earth
2 A. Maps and Globes1. Globe- 3 dimensional representation of the earth
3 2. Maps- 2 dimensional representations of selected parts of the earth’s surface a. maps’ functions: show locations of places, landforms & bodies of water & their relations to other places in the worldb. easily portable & can be drawn to any scale needed
4 3. cartographer: mapmaker 4. map projection- way of drawing the earth’s surface that reduces distortion caused by putting a round earth on flat paper
5 5. Types of Mapsb. political- show features on the earth’s surface created by humans (ex. cities, states, territories, provinces, countries)a. physical- landforms & bodies of water found in a specific area
6 c. Thematic or special purpose maps - focus on specific types of information (ex. climate, vegetation, natural resources, economic activities)d. flow-line- shows movement of people, goods, ideas, animals, etc.
7 Special Purpose Map Example: Climograph What is the weather like in July?
8 6. Items found on a map: a. title- explains subject of map b. compass rose- show direction (north, east, south, and west)c. labels/words- explains the features on the mapd. legend/key- lists & explains symbols & colors on a mape. lines of latitude and longitudef. scale- unit of length on a map & a unit of distance on the earthg. symbols- cities, natural resourcesh. colors
9 Label water in Blue Ink and use Black Ink for everything else on your map. Use a dot for cities.Use a star for capitals.In a political map, alternate shading of the countries so that no one country of the same color borders each other.LCHS RCaulder
11 Mountain Peak in a solid Brown Mountain Range outline in Brown Coloring a MapMountain Peak in a solid BrownMountain Range outline in BrownPlains, valleys, peninsulas, forests are colored GreenDeserts are Yellow with black dotsWater is Blue and can only be used for waterLCHS RCaulder
13 B. Mapmaking1. Geographers complete a field survey before making a mapa. observes, measure, & record what they see in an areab. done by aerial photography or satellites
14 2. Well known satellitesa. Landsat- satellites that orbit more than 100 miles above the Earth (scans the earth in 16 days)
15 b. Geostationary Operational b. Geostationary Operational Environmental Satellite (GOES) - goes in orbit with the earth’s rotationused to help forecast the weather
16 3. Geographic Information System (GIS) - 3. Geographic Information System (GIS) - stores information about the earth in a digital database4. GPS (Global Positioning System) - exact position of (latitude, longitude, altitude, time) a location displayed on a hand held receiver
