Definition

  • Geodesy is the branch of mathematics concerned with the shape and area of the earth and with the location of points on it.

  • Cartography is the art, science, and practice of making maps.

  • A map projection, or simply a projection, is any systematic representation of the earth's surface onto another surface.

  • The Global Positioning System, or GPS, comprises a network of satellites that orbit the earth and, by radio communications with land-based receivers, enable the accurate determination of the coordinates of points on the earth's surface.

  • Spherical geometry is the study of lines, angles, and areas on a spherical surface.

Historical Background

The foundation of geographical information science (GIS) lies in our ability to determine the size and shape of the earth, locate points on its surface, measure its features, and to portray the earth in maps. Thus, geodesy and cartography form the basis of GIS. In turn, both of these subjects are built on strong...
