MAPS AND GLOBES• Maps are instructional materials which

represent the Earth’s or portion of the Earth’s surface. Globes, on the other hand, are spherical models of the Earth. However, even though a globe is three-dimensional, it can be classified as a “graphic” because of the use of symbols, words, and drawings.

Classification of Maps

• Physical maps – emphasize terrain and topographical concepts

• Political maps – emphasize man-made phenomena such as state, city or provincial boundaries or location of highways or railroads or government buildings

• Special purpose maps – these are the maps used for perculiar purposes like those presenting amount of rainfall, population distribution, and travel routes.

Classification of Globes• Political globes – show location and

boundaries of cities, provinces and other man-made structures.

• Physical-political globes – show some political features but emphasize land elevations and ocean depths.

• Special purpose globe – these are globes constructed for specific purposes such as satellite globes, celestial globes, and physical relief globes.
