Ergonomists study how people interact with products and how products can be designed to be safer, more effective and satisfying. Product developers find the most cost effective methods and materials to produce the product. By examining different methods of packaging, packaging engineers determine how the product will be packaged and what it will cost. Environmental engineers study how the product will affect the environment-how fast the product will disintegrate when disposed of, how durable it is, what materials it will be made out of, etc. Cartography Cartographers obtain and interpret information collected by surveyors on the ground and satellites in space to make maps that graphically represent different aspects of our world.
Geographers collect, study, analyze, and organize information about the Earth's surface.
They may study the politics, climate, vegetation, and other aspects of a region. Surveyors use a variety of mechanical and electronic devices to measure exact distances and locate positions on the earth's surface. Cosmographers locate and study celestial and cosmic bodies or structures in space. Hydrographers locate and study the movement and distribution of bodies of water. Computer assisted cartographers collect and interpret geographic information using computers.
