Global Positioning System
• Data collection units which provides accurate positioning of people, objects and activities on the earth’s surface. Co-ordinates are available in latitude/longitude or in a map projection system e.g. Universal Transverse Mercator (UTM)

Remote Sensing
Sensor systems can be placed in an aircraft or on a satellite. Systems can be traditional e.g. aerial photographs, LANDSAT images. They can be non traditional e.g. LiDAR, multi-beam sensor, hyperspectral.
The end result is a digital raster with pixels and intensity values.

Geographic Information System (GIS)
GIS is a software system used:
1). To store spatial and non-spatial information
2). To conduct spatial analysis
3). To display the results in graphs or statistical form
4). To share information across the Internet

What is Geographic Information Science?
It is the conceptual basis for conducting spatial analysis. It includes questions of, scale, resolution, error, relationships, models, representations, statistics.

• Physical landscape
• Socio-economic landscape
• Three-dimensional representation
• Four-dimensional representation
