Hi

On a screen coordinate system(800 x 600), we have the current location(both
pixel coordinates and geogaphical coordinates (latitude and longitude)) and
the direction of movement (angle in degrees with respect to north) of a
moving object( say gps device).
What is the best way to determine the coordinates of the point on the screen
border in the direction of movement ?

Ultimate aim is to calculate the time required to reach the border if the
object is assumed to be moving in the direction at that instant.
