1. A method of delivering graphical weather images through a satellite to an aircraft, the method comprising:
- determining an expected position in time and space of the aircraft based on a flight plan of the aircraft; and
automatically transmitting an updated graphical weather image to the aircraft via the satellite, the updated graphical weather image being focused on an area of interest with respect to the expected position in time and space of the aircraft at a time when the aircraft is expected to receive the updated graphical weather image via the satellite.

Abstract
A method for creating minimal data representing a source image is presented. The source image is divided into a grid of cells. A color is selected for each cell corner based on sampling an area defined by the cell corner. An indication of the selected color is stored in an array dependent on the co-ordinates of the cell corner in the source image.
