Thinking of a a career in Geospatial Technology? This career is an information technology field that acquires, manages, interprets, integrates, displays, analyzes, or uses data that focuses on geographic, temporal, and spatial contexts. Geospatial technology is also known as geometics outside of the United States. The technology involved is complex and is one of the emerging industry that is changing the way we live just like what computers did to us decades ago.
Here are some of the career in Geospatial Technology fields that you can be involved in.
Photogrammetry is using the knowledge of science and technology to obtain 3 dimensional coordinates of objects based on the two or more photographic images taken from different angles from aerial or space photography. The Photogrammetrists are responsible for such mapping projects and provide spatially accurate base maps that form a foundation of geographic information systems applications.
Remote Sensing is using the knowledge of science and technology to obtain information about Earth objects and environment without physical or close contact with the objects. Most of the time, these information are gathered using satellites, spacecraft and aircraft. Some of the aircraft can be unmanned. The measurement is done by analyzing the variations in electromagnetic waves(visible light, near infrared, mid infrared, thermal and microwave energy) as they interact with the objects.
Geographic Information Systems
Geographic Information Systems(GIS) is an integrated computer system that allows users to integrate, store, edit, analyze, share and display geographically referenced information. The system basically need to have huge data storing and processing capability, fast processing time and a good graphical display as the amount of data to be processed will be enormous for small system to handle. Making maps and developing GIS software are parts of the job of a GIS analyst.
Geodesy is the scientific discipline that deals with the measurement and representation of the earth, the gravitational field and geodynamic phenomena (polar motion, earth tides, and crustal motion) in 3-Dimensional, time varying space.
Global Positioning System
The Global Positioning System uses more than two dozens of GPS satellites that allow us to accurately determine the location of a specific object on earth at anytime of the day. This technology is used to help navigate traffic system to avoid congestion, anti theft system that will immobilize a vehicle if activated, military, surveying, aircraft passengers calling someone from the airplane, geology and other applications.
