Definition
Cartographic representations allow you to store and render additional information with the geographic features on a map.
With representations, you can produce
1.Multiple map products from a single master database
2.Scale-based map products
3.Map series products |

Since a map is a reduced representation of the real world, map symbols are used to represent real objects.
Both shapes and colors can be used for symbols on maps |

| The smaller the number on the bottom of the map scale, the more detailed the map will be. A 1:10,000 map will show objects ten times as large as a 1:100,000 map but will only show 1/10th the land area on the same sized piece of paper. |

Definition
the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space. Geodesists also study geodynamical phenomena such as crustal motion, tides, and polar motion. For this they design global and national control networks, using space and terrestrial techniques while relying on datums( and coordinate systems.
a set of reference points on the Earth's surface against which position measurements are made, and (often) an associated model of the shape of the earth |
