8.  Geography is the study of where things are found on Earth’s surface and the reasons for the locations.  Human geographers ask two simple questions… 1. Where are people and activities found on Earth? 2. Why are they found there?

9.  A map is a two-dimensional or flat-scale model of Earth’s surface, or a portion of it.  Cartography is the science of mapmaking.  Maps serve two purposes… 1. As a reference tool to identify an object’s absolute and relative location. 2. As a communications tool to convey the distribution of human activities or physical features.

10. A stone tablet found in a cave in Abauntz in the Navarra region of northern Spain is believed to contain the earliest known representation of a landscape.

11.  Earliest maps were reference tools — simple navigation devices to show a traveler how to get from Point A to Point B.  First world map prepared by Eratosthenes(276 – 194 B.C.) › Improvements to world map later made by Ptolemy. › After Ptolemy, advancements in cartography primarily made outside of Europe by Chinese and Islamic world.  Mapmaking revived during the Age of Exploration

16.  Level of detail and the amount of area covered on the map depend on its map scale.  Other Words…The degree to which a map “zooms in” on the area it is representing.

17.  Map scale is presented in three ways… 1. Ratio or Fraction Scale : Ex. 1:24,000 or 1/24,000  Number on left is one unit of distance, while number on right represents same unit of distance on Earth’s surface. 2. Written Scale: Ex. 1 inch equals 1 mile  Number on left is one unit of distance, while number on right represents a different unit of distance on Earth’s surface. 3. Graphic Scale : Usually consists of a bar line marked to show distance on Earth’s surface  Distance between two points can be overlaid on the scale bar to determine the distance on Earth’s surface.

19. “LARGE” OR “SMALL” scale. › The more “zoomed in” the map is on an area, the larger is its map scale.  large-scale map depicts a smaller area › The less “zoomed in” the map is on an area, the smaller is its scale.  Small-scale map depicts a larger area

23.  Show locations of places and geographic features.

24.  Tell a story about the degree of an attribute, the pattern of its distribution, or its movement.

25.  Contour maps use contour lines, to depict where the same elevation exists.  The contour interval of a contour map is the difference in elevation between successive contour lines.

27.  The proportional symbol technique uses symbols of different sizes to represent data associated with different areas or locations within the map.

28.  A dot may be used to locate each occurrence of a phenomenon.  Where appropriate, a dot may indicate any number of entities, for example, one dot for every 100 voters. Military families in Ohio

29.  Shows statistical data aggregated over predefined regions, such as counties or states, by coloring or shading these regions.

30.  A cartogram is a map in which some thematic mapping variable is substituted for land area or distance.  The geometry or space of the map is distorted in order to convey the information of this alternate variable.

32.  Global Positioning System  Satellite-based system for determining the absolute location of places or geographical features

33.  A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.  GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.
