READING MAP GRIDS: LATITUDE/LONGITUDE & TYPES OF MAPS GRIDLINES: LONGITUDE/LATITUDE 2 TROPIC OF CANCER = _____ TROPIC OF CAPRICORN = ____ ARCTIC CIRCLE = _______ ANTARCTIC CIRCLE = ______ NORTH POLE = ______ SOUTH POLE = ______ 3 ON Your Packet notes: Draw the CARDINAL DIRECTIONS (a “Compass Rose”) 4 Types of maps & info on maps: physical maps: show landforms of an area Use colors to show relief— difference levels in land elevations -green usually = lo elevations -orange or brown = hi elevations Topographical: Presents horizontal & vertical positions of features represented -shows -Uses contour relief in measurable form.lines (isolines) to show the shape & elevation of an area (shape of the Earth’s surface) -Lines close together indicate steep terrain -Lines far apart indicate flat terrain. EX:? 5 TYPES OF MAPS Political maps: show places divided by states (aka “countries”), cities, counties, etc. -usually show rivers, major lakes, oceans, etc., elevations….capital cities show w/ star Economic maps: type of thematic map that shows natural resources in areas and/or ways that people make a living; legends may show mines, factories, power plants, etc. NOTE: the economy of a country is the way the money is earned, used, spent, controlled, issued, invested, etc. 6 Thematic Maps: Provides info on a single topic (population, rainfall…) Using Thematic Maps: shows comparison of statistical data, like population or income -can view facts about places by comparing the patterns of shaded areas or colors on the map. Chloropleth maps (4-H/Ohio .. Afr.savannahs) (Gk.: for “place” + “value or magnitude”): Thematic map w/ areas colored, shaded, dotted, or hatched so have darker/lighter areas in proportion to density of whatever aspect U R are looking -show amt. of some “phenomenon” (some event or thing which occurs) like ratios, %, etc., using these colors 7 Cartogram here shows GDP (gross domestic product) thru world Cartogram: Shows some quantity or value by shape or size of a region Reference Maps- Tool to view boundaries of census geographies, cities, counties, cities/towns, urban areas,congressional districts, census tracts, census blocks, & more. Note: some of these terms overlap 8 Map projections: See Appendices Pp. 503 – 507 Cylindrical, conic, & planar Equal area projections 9 WORLD GEOGRAPHIC GRID The world geographic grid consists of meridians of longitude & parallels of latitude. The prime meridian (0º) passes thru Greenwich, England. 10 Which is a(n).. A ..cartogram? ..chloropleth map? ..economic map?
