Warm up
• (Table)
• What do the latitude and longitude of Boston,
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
Latitude, longitude
Tells distance from equator, distance from
Prime Meridian
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,
