Map Projections

All flat maps have some distortion in their representation of: Distance Shape Area Or direction.

Equal-area (or equivalent) projections: maps that maintain area but distort other properties. Conformal (or orthomorphic) projections: maps that maintain shape but distort other properties (it is impossible to have a projection that is both conformal and equal area). Azimuthal projections: maps that maintain direction but distort other properties. Equidistant projections: maps that maintain distance but distort other properties. Types of Projections

Mercator Projection

Cylindrical

Planar (Azimuthal)

Planar (Arimuthal)

Combining Maps and Technology { GPS and GIS

Using GPS- Global Positioning System Used to track routes- cars/boats, etc Can track animals (ex. migration routes)

Using GIS GIS- Geographic Information System Technology that uses digital map information to create a databank Different data layers can be combined to produce specialized maps. Used to analyze to solve problems http: //www. smithsonianmag. com/videos/c http: //www. pbslearningmedia. org/resourc ategory/3 play_1/anne-kelly-knowles-usese/psu 10 sci. vid. geospatial. whystudy/geosp gis-tools-to-re-writ/ atial-revolution-why-study-gis/

As new technologies link people all over the world, having an understanding of geography is more important than ever. Do you agree? Why or why not? Cloud= File info into your brain! Words with Friends= Work with a partner
