Map Projections

Start with the basics

Map Projections is a section of Map Skills and GIS in Geography. Its resources connect the idea of representing a curved surface on a flat map with projection types and their features. They include mind maps, quizzes, flashcards and a slide set made by GoConqr users.

Start with the mind map Projection. It introduces the idea of representing a curved surface on a flat surface and groups terms such as cylindrical, conical and azimuthal. Use its branches to see which terms you recognize before moving on.

Build the picture

The mind map on cartographic foundations brings in the geoid, ellipsoid and sphere, as well as meridians, parallels and the global coordinate system. The mind map Mapping groups projective projections by the surface or geometric figure used.

For a closer look at distortion, use the mind map on map projection that discusses changes in shape. The flashcards on maps also include named projections and a point about distortion increasing away from the equator. These resources give you different ways to organize the terms on the page.

Practice with quizzes and cards

After studying a map, try Maps: Geography's Basic Tools, which asks about transferring features from a globe to a flat map. The Cartographic Foundations Quiz includes questions on the sphere, meridians and coordinates.

Use Final Vocab to review terms including cylindrical, conic and planar projections. Return to a mind map when a term or question is unfamiliar, then try the relevant quiz again. This keeps the projection resources connected to the wider Map Skills and GIS unit without losing sight of the details. Choose a resource and explore the section at your own pace.
