MEX-M-HRSC-4-REFDR-MAPPROJECT-EXT7

This data set contains map projected data products acquired by the HRSC camera on the Mars Express spacecraft, covering the orbits 18976 to 21487. As part of the processing compressed images are decompressed and radiometrically calibrated (CODMAC level 3). After this the images are converted to 8 bit using a histogram optimized lookup table. Then the optical distorsion is corrected. As the last step the images are map projected. The type of the map projection depends on the latitude of the image center and the extent of the image. Additional geometric information (e.g. footprint and illumination angles) are calculated and included into the image label. Images without useable content (e.g. completely saturated images) are omitted from the data set. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]

本数据集收录了由火星快车号搭载的HRSC相机所获取的地图投影数据产品，涵盖了18976至21487的轨道范围。作为处理流程的一部分，压缩图像被解压缩并进行辐射定标（CODMAC级别3）。随后，图像通过直方图优化查找表转换为8位图像。接着，对光学畸变进行校正。最后一步是将图像进行地图投影，地图投影的类型取决于图像中心的纬度和图像的范围。此外，计算并包含在图像标签中的额外几何信息（例如足迹和光照角度）亦一并录入。对于无可用内容的图像（例如完全饱和的图像），则从数据集中予以排除。详情请参阅实际数据，[截断！请参阅实际数据以获取全文]。
