Study Notes

Map Reading: Plans and Photographs

  • Plans are two-dimensional diagrams showing the layout of a place.
  • Plans are often used for large malls, airports, hotels, amusement parks, and museums.
  • Photographs are useful because they show detail and cover wide areas.
  • Geographers use ground-level, oblique-angle aerial, and vertical-angle aerial photographs.

Objectives

  • Students should be able to explain what is shown on maps, plans and photographs.
  • Students should be able to identify different types of plans and photographs.
  • Students should be able to differentiate between oblique-angle and vertical-angle aerial photographs.

Types of Photographs

  • Ground-level photographs: Photos taken from the ground. Example of ground level photographs are photos of a river, with people using measuring devices.
  • Oblique-angle aerial photographs: Photos from a slanted plane angle. Oblique photographs can show a wide area but aren't always precise.
  • Vertical-angle aerial photographs: Photos from a straight-down plane angle. Vertical photographs offer clearer, accurate measurements as the angle is precise. Aerial photos can be taken from aircraft and satellites.

What is a Plan?

  • A plan is a drawing or two-dimensional diagram that represents the layout of a space.
  • Plans are helpful in many projects and show a detailed, two-dimensional view of a space.
  • Plans can be used to show everything from the design of a home to the layout of an airport.

Activity

  • Take 2 minutes to sketch a plan of your favorite room from memory.
  • Reflect on why sketch layouts are important.

Further Considerations

  • Photographs are used by geographers to understand places.
  • Photographs can offer different perspectives (e.g., ground level, oblique angles, vertical angles) for gathering information.
  • Different angles of perspective can influence the accuracy and use of photographs.
