日本《遥感技术中心通报》(RESTEC)1986年9月第17期发表了向井幸男等根据相邻轨道TM资料通过计算机处理求出地面高程的技术报告。其试验概况如下。试验区的轨道号是108—35(为右幅,1984年12月13日,日本长野)与109—35(为左幅,1985年11月21日,日本飞弹),重叠区周边长约40公里,取中央部分,其平地标高为600米,山顶标高为2800米。试验区的高差为2200米。 TM资料经过整体校正,选用32个地面控制点,布置了250米间隔的格网点,根据格网点的对应点通过计算机处理以3次式内插求得50米间隔的内插点
Japan’s Remote Sensing Technology Center Bulletin (RESTEC) Sept. 17, 1986, published a technical report by Inoue Yukio et al. On calculating ground elevations by computer processing based on TM data of adjacent orbits. The test is as follows. The test track number is 108-35 (for the right, December 13, 1984, Nagano, Japan) and 109-35 (for the left, November 21, 1985, Japanese missiles), the area around the overlap is about 40 Km, take the central part of the flat landmark height of 600 meters, the peak elevation of 2800 meters. The test area elevation is 2200 meters. TM data through the whole correction, the selection of 32 ground control points, the layout of the grid spacing of 250 meters, according to the grid point corresponding points through computer processing to obtain three cubic interpolation 50-meter interval interpolation points
