1. A method for synthesizing color imagery for a predetermined project area, comprising: inputting a high-resolution natural color sample of a sample area contained within the project area; inputting a multi-spectral image of said sample area, said multi-spectral image having a plurality of feature types; generating a color palette for each of said plurality of feature types based upon said high-resolution natural color sample; applying said color palettes to a multi-spectral image of the project area to generate a low-resolution natural color image of the project area; and combining said low-resolution natural color image of the project area with a high resolution panchromatic image of the project area to generate a high-resolution natural color image of the project area.
