Screen coordinates are used to position text boxes, images, and videos on
The coordinate system is defined in terms of a percentage of the screen
dimensions so that both the x- and y-positions are between 0 and 100 regardless
of the size or aspect ratio of your screen. The origin, (0, 0), is at the
bottom-left corner of the screen. Objects are positioned so that their center
sits at the defined point.
A text box placed at position (10, 10), for example, would appear in the
bottom-left corner of the screen. An image placed at (50, 50) would be centered
on the screen. And a video positioned at (90, 80) would appear at the top-right
of the screen.
SOS Explorer® uses an
cylindrical equidistant projection. This means you can simply treat values of
longitude as x-coordinates ranging from -180 to +180, and values of latitude as
y-coordinates ranging from -90 to +90. The origin, (0, 0), is at the center of
