法国国家空间局(CNES)1986年的SPOT成像系统在卫星图像地质构造制图方面有两项明显的进展:一是提高了主要构造和地层要素的空间分辨率;二是测定走向、倾角的立体功能。可用硬拷贝图像和常规装备如立体绘图仪或者以立体观察形式在视频监视器上显示图像来进行SPOT资料的定量主体制图。后一种方法是特别适用于勘探团体的新的遥感技术。这一技术使得能以少量的花费和培训,用现有的图像处理系统或独立个人计算机进行有效立体制图。 SPOT立体资料对低幅度和高变形构造的制图特别有用。由立体图像资料产生的地表构造图可在两个层次上用于勘探。早期阶段这些图件可用于建立一个盆地中构造的风格、走向、大小及空间分布,以及调查关键构造要素。在更高级的勘探阶段,这些图件可用于约束低品质地震资料区的地下构造制图。然而这后一种技术或许需要有更高分辨率的立体航空摄影的支持。
The 1986 SPOT imaging system of the French National Space Agency (CNES) made two distinct advances in the mapping of satellite image geologic formations. The first is to increase the spatial resolution of major structural and stratigraphic elements. The second is to determine the spatial and spatial features of strike and dip . Quantitative master mapping of SPOT data can be performed with hard-copy images and conventional equipment such as a stereograph or stereoscopic viewing on a video monitor. The latter approach is a new remote sensing technology that is particularly suitable for exploration communities. This technology enables efficient stereo mapping with existing image processing systems or stand-alone personal computers with minimal expense and training. SPOT stereoscopic data is particularly useful for mapping low-amplitude and high-strain structures. Surface texture generated from stereoscopic imagery can be used for exploration on two levels. These early pieces can be used to establish the style, orientation, size and spatial distribution of structures in a basin and to investigate key structural elements. In more advanced stages of exploration, these maps can be used to constrain subsurface structures in low-quality seismic data areas. However, this latter technique may require the support of higher resolution stereo aerial photography.
