1 Making Sense of Maps Doug R. Oetter Dept. of History and Geography Georgia College & State University6 October 2004
2 Geography Study of Earth phenomena Includes an analysis of distributional patterns and interrelationships among these phenomena.
3 Two Branches of Geography Human geographyPopulations & MigrationsCulture (Languages, Religions)RegionsTrade & TransportationGeopoliticsPhysical GeographyMeteorologyGeomorphologyBiogeographySoil science
4 Technology, Tools, and Methods of Geography MapsPhotographs and satellite imagesSurveyingGlobal Positioning SystemField work and remote measurementsInstrumentsGeo-statistics
5 Maps Maps are a way to record and store information Maps are a means of analyzing locational distribution and spatial patternsMaps are a method of presenting information and communicating findingsMaps are 2-dimensional representations of a 3-dimensional spheroid
6 Maps and Mapping Advantages of Maps Limitations of Maps Graphic representations with symbolic languageShow spatial relationships with great efficiencyCan be changed through time and spaceUseful to laypeople as well as geographersLimitations of MapsCan never be completely accurate because they leave out detail and conditions changeMap distortion is inherent due to the Earth’s curvature
7 Global Grid Parallels are always parallel and evenly spaced 111 km (69 mi)Meridians converge at the polesMeridians and parallels cross at right angles
16 ChartsSpecially designed to serve the needs of nautical and aeronautical navigators
17 Small vs. Large Scale Small scale Large scale small amount of detail small RFLarge scalelarge detaillarge RF
18 Exercise 1: What Type of Map is This? What does it show?What scale is it?
19 What makes a Good Map? What is the motive, intent, or goal of the map? Who will read the map?Where will the map be used?What data are available for the composition of the map?What resources are available in terms of both time and equipment?
20 Exercise 2: Can you Make a Map? Mental MapsA person's perception of the world is known as a mental map.A mental map is an individual's own internal map of their known world.
