摘要：
By integrating SPOT's panchromatic channel with 10-m resolution into its multiband channels with 20-m resolution, it is possible to produce a high resolution image suitable for photo interpretation. Three different integration algorithms have been tested on simulated SPOT data in order to produce color composite images using SPOT's multispectral mode (three channels) in combination with its 10-m resolution panchromatic mode. The algorithm that gave the best visual results used a different integration formula for the near infrared channel than for the green and red channels, due to the fact that the panchromatic is less correlated with the infrared than with the visible channels. The result looks very similar to a color infrared air-photo with high resolution and good spectral information quality.
