9.18 Showing Scale on Screen

Notes about scale
Scale is a relation of distance between two points of the map with the corresponding distance on the Earth's
surface. It is generally indicated by a fraction or a relation between linear distances indicated on the map and
corresponding distances on the Earth's surface.
Numeric scales can be represented by a direct relation of multiplication or through a relation of distance. GPS
TrackMaker® uses the second method, because it is more intuitive and easy to understand. Thus, the scale of
1:100 km indicates that 1 cm on the map is equal to 100 km on the Earth's surface.
For the English system (yards, miles, etc), the relation will take inches as a base. This way, the scale 1:50 miles
indicates that 1 inch on the map (2,54 cm) corresponds to 50 miles on the Earth's surface.
Scale indication at GPS TrackMaker®
To enable scale indication on screen, choose View > Scale or press <CTRL E>.
Scale indication will appear in the upper left corner of the screen, as indicated in the illustration.
For scale calculation, the program always considers the linear horizontal length of the center of
screen. Thus, in larger scales (1:500km, 1:1000 km, etc), distortions can occur among the values indicated in scale
and the real scale in areas around the screen's edges.
Scales can be changed in the Scale box in Tool Bar. Just click on one of the scales indicated in the box so the
screen will be modified to the respective scale.
