Any system that uses maps must take into account three properties: datums, coordinate systems, and projections. These properties specify our model of the Earth and the way in which we specify locations upon it. In the world of geodesy there are a number of different options for each of these properties with no one ˵best fit″ choice for all applications. While it is often not necessary to use more than one datum or coordinate system, it is important to understand them in case there is a need for interoperability with another system or data source which uses a different datum or coordinate system. As such, we will provide a general introduction to these two properties. [ABSTRACT FROM AUTHOR] |
