ABSTRACT:
Cloud cover information over a selected portion of the earth, such as that obtained from a satellite (10) is converted into digital form and stored in a picture memory RAM (40). The memory can be interrogated and displayed on a television monitor (100) or transmitted by a television station (110). Geographical information, such as the location of water bodies and land masses, stored in a map memory ROM (50), and this memory is interrogated at the same time as the picture memory to generate a color subcarrier which is added to the video from the picture memory. The hue of the combined picture is varied according to the intensity of the video signal from the picture memory by means of a combinational logic circuit (60). The combined black and white video from the picture memory RAM and the color subcarrier generated by the map memory ROM will provide a composite video signal with water bodies represented by a color different from the color representing land masses and where the intensity of the color generated will be an inverse function of the intensity of the video signal.
