Exercise 4 -Amy Fong
This map illustrates a worldwide network of the locations of satellite stations and submarine cables. The stations and cables are shown by using varies shapes and sizes of lines along with different colour that differentiate satellites in geostationary orbits around the earth. Some of these satellites and submarine cables include; the Earth Station, Earth Station Operating with Two Satellites, Submarine Cable Terminal, International Centre, Cable Depot, Canada/ Other Partnership, Circuits Leased by Canada, IRU Circuits Owned by Canada, Planned (fiber-optic), Planned introduction of service and Internal Networks. The designer used lines to present and link the connections between the earth stations to the satellite stations. The map is designed in a way that presents a legend located on the bottom of the map which allows the viewer to understand the relationship between the satellite earth stations and the cables owned, leased or operated by Canada. Even though this map displays a worldwide network, the information is limited to the Canadian satellite system. This map is very easy to read because of the signs and symbols (different lines and colour coded shapes) offered by the legend that help the viewer comprehend the map.
