1. Most of the exercises on this website use a Project Map that
covers the Atlantic Ocean adjacent to the African country of Liberia.
The important measures of the map are:
Top (latitude): +9.0 degrees
Bottom (latitude): -6.0 degrees
Left (longitude): -23.0 degrees
Right (longitude): -3.0 degrees
Height: 15 degrees
Width: 20 degrees
The terms North, South, East and West are not used in the
correct notation of signed decimal degrees. For simplicity and to avoid
off all values to whole degrees. This map also covers the entire coastlines
of the neighboring countries of Sierra Leone and Cote d'Ivoire. There is
no political basis to the arbitrary selection of this area, and it is only
chosen for educational purposes due to the interesting nature of the area.
