The study of gathering and processing geographic information, as well as sharing this information. Some major subfields of this area include surveying, mapping and global positioning systems.
Geodesy is the study of the size and shape of the Earth's surface and the creation of theoretical mathematical models of the surface that best fits the physical data.
GPS (Global Positioning System) consists of 24 satellites in orbit. With appropriate receiving equipment the system can be used to determine geographical co-ordinates such as position and height. There are many uses of GPS including navigation, mapping, surveying, and monitoring.This Open Directory Category is for GPS sites that relate to Geomantics, that is the study and measurement of the physical environment of the earth.

The science of obtaining data about structures, objects and physical features of the earth through the processes of recording and interpreting photographs and other electromagnetic imagery.
Remote sensing is the gathering of information about an object without being in physical contact with the object, usually by methods that detect electromagnetic energy. Such observations are often made from spacecraft and aircraft.
