Anaheim and St. Petersburg tell us?• Region of country, neighbors, plate• Hemisphere• Coast - longitude• Climate – latitude• Time zone
• Boston – 42o N, 71oW
• Anaheim – 33oN, 117oW
• St. P – 27oN, 82oW

Warm up
• Draw a scale model of your table
Scale
• Measure then shrink or grow
• Map scale the ratio between the model and actual
• 1:25000
• 1cm to 25 000 cm – Boston topographic map’s scale or 1 cm to 250 m (0.25km)
• Sketch a map of the stairs
• Mercator – cylindrical, distorts near poles, good for navigation, line of latitude and longitude are perpendicular
• Planar – gnomic, polar projection, good at a pole, distorts equator, etc
• Conic – polyconic, good for smaller areas, US map
