What is the art of making maps called? Cartography – the art of making maps
A map is a drawing or a picture of the earths surface, showing how things are related to each other by distance, direction and size.
Maps are used for: Navigation : To find places Direction to travel Determine distance Determine Size Visually display data
Types of Maps Topographic map – Shows elevation of the land Shows 3 dimensional ups and downs on 2 dimensional surface Population density – How many people live in an area (crowdedness). Road maps, School Maps, Weather Maps, Etc…
What is on a Proper Map? Title – Tells what map you are looking at. Key / Legend Shows representations of objects on the map. Scale – Shows distance on a map.
Compass – gives direction (N,S,E,W) WE not EW to get out of the woods. Landmarks/features – objects such as mountains, buildings, parking lots ect. Roads with names – roads are labeled to clarify which roads you are looking at Latitude and longitude For navigation
How do we tell which is which?
Latitude is the Measure of distance north and south of the equator. (Laddertude, Flatitude) What is its range? Latitude range = 0° – 90° N or S What are lines of equal latitude? Parallels are lines of the same latitude running East and West on a map Parallel to the Equator What is 0 Degrees Latitude? Equator - 0° latitude Halfway between North and South pole
North Pole: 90° N Arctic Circle: 66.5° N Tropic of Cancer: 23.5° N Equator: 0° Latitude Tropic of Capricorn: 23.5° S Antarctic Circle: 66.5° S South Pole: 90° S All #’s relate to 23.5 Earths Tilt
Longitude is the measure of distance east and west of the prime meridian Longitude Range? Longitude Range 0° - 180° E or W Can only go half way around a circle Lines of equal Longitude? Meridian - Lines of equal Longitude. Run between North and South Pole Zero Degrees Longitude Prime Meridian – 0° longitude Runs through Greenwich, England What is the name for 180° The International Date Line is 180 Deg. Longitude
We started using Latitude / Longitude For ship navigation Poor navigation = Bad Day
Latitude / Longitude for Lagrangeville, NY? Lat / Long for Lagrangeville, NY 41 Deg. North / 74 Deg. West
Latitude first, must always include N or S Longitude second, must always include E or W Start at equator and go N or S the number of degree Start at the Prime meridian and go E or W the number of degrees The intersection of the two lines is your location
40° N3° W Madrid, Spain 36° N112° W Grand Canyon National Park 0°N36° E Nairobi, Kenya 33° S70° E Santiago, Chile 28° N81° W Disney World - Orlando, Florida
Time zones - Longitudinal belt in which all areas have the same local time Why do we have time zones? Since the Earth rotates, not all places are in daylight at the same time. To accommodate for this, different places are set to different times
Where is the starting point for time zones? The 0 point for time is 0° Longitude or the prime meridian (Greenwich Mean Time (GMT). How far apart is each time zone? Every time zone is 15 Deg. Apart. 360° / 24 hours = 15° / hour What happens to time when we move to the West? Every 15 deg. you move West we subtract 1 hr (Lazy Californians) What happens when we move to the East? Every 15 degrees to the East we add 1 hour (Busy NYC)
Can we go back multiple days in time? To stop us from going to far back or forward in time, the International Date line resets the day. What happens when we cross it? Crossing to the west we add one day. Crossing it to the east we subtract one day It is the opposite of time zones! Why is the line not straight with the 180 deg meridian? The line does not run perfectly North and South, it bends around islands in its path
US time zones: Eastern Standard Time Central Standard Time Mountain Standard Time Pacific Standard Time Alaska and Hawaii
What is the best representation of the Earth? The best representation of the Earth is a Globe. What happens when we try to make a map the Earth? When the round surface of the Earth is projected on a flat surface changes occur that distort the size and shape of land and oceans
Mercator Maps show correct shape of coastline Distorts the size of land and water areas far from the equator Greenland is made much larger then it really is.
Equal Area Maps shows area correctly Distorts the shapes
1.) What is a map? 2.) What is the study of maps known as? 3.) Name and explain 3 kinds of maps people would use? 4.) What are 8 important features on a map (define) 5.) What changed from your first map to your final map? (Meaning did you add or change anything.) 6.) Explain 2 types of maps that try to fix the problem of distortion.

Conclusion: Define Latitude ? Define parallels ? (in terms of latitude) What is the zero point for Latitude ? Define Longitude ? Define Meridian ? (in terms of Longitude) What is the zero point for Longitude ? What are time zones, Why do we have them and how many degrees are between them? What is the International Date Line, where is it and why do we have it ?
