已经开发了几种技术来合并SPOT 10米分辨率全色数据和同时获取的20米分辨率多光谱数据。通常，这些程序的目标是创建增强可解释性的合成图像。也就是说，通过各种合并方法产生的有效的10m分辨率多光谱图像包含各个全色图像的高分辨率信息，同时保持原始多光谱数据的基本颜色内容。说明了强度-色相-饱和度(IHS)转换过程在不同土地覆盖条件下创建这种复合材料的实用性。对原始多光谱图像数据及其在IHS合成中的对应数据的相关性分析表明，需要仔细考虑IHS程序的替代实施可能对所产生的多分辨率产品的光谱特性产生的潜在影响。在这项研究中，使用全色和近红外数据的加权平均值作为合并图像中强度的替代被发现特别有效。这种方法已经用于制作威斯康星州麦迪逊及其附近地区的试验性SPOT图像地图。
Several techniques have been developed to merge SPOT 10-m resolution panchromatic data with simultaneously-acquired 20-m resolution multispectral data. Normally, the objective of these procedures is to create a composite image of enhanced interpretability. That is, the effectively 10-m resolution multispectral images produced through the various merging methods contain the high resolution information of the respective panchromatic images while maintaining the basic color content of the original multispectral data. The utility of intensity-hue-saturation (IHS) transformation procedures for creating such composites under varying land cover conditions is illustrated. Correlation analysis of original multispectral image data and their counterparts in IHS composites indicates the need to consider carefully the potential influence alternative implementations of IHS procedures might have on the spectral characteristics of the resulting multiresolution products. The use of a weighted average of panchromatic and near-infrared data as a substitute for intensity in merged images was found to be particularly effective in this study. This approach has been used in the production of an experimental SPOT image map of Madison, Wisconsin, and vicinity.
