Pan-sharpened example — Old Mission Point Orchards (2011). The 1 m panchromatic is fused with the 4 m multispectral to yield a 1 m color image. Typical things you can now detect:

• Individual trees and tree rows in the orchards.
• Buildings, driveways, vehicles, fences.
• Crop vigor differences via the multispectral component.

Pan-sharpening is a standard IKONOS workflow — trades a little spectral fidelity for major spatial detail.
