MEX-M-HRSC-4-REFDR-MAPPROJECT-EXT2

This data set contains map projected data products acquired by the HRSC camera on the Mars Express spacecraft, covering the orbits 4919 to 6836. 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]

本数据集收录了火星快车号（Mars Express）搭载的HRSC相机获取的地图投影数据产品，涵盖了轨道4919至6836范围内的数据。作为处理过程的一部分，压缩图像被解压缩并进行了辐射校正（CODMAC三级校正）。随后，图像通过直方图优化查找表转换为8位深度。接着，对光学畸变进行了校正。在最终步骤中，图像被进行地图投影，投影类型取决于图像中心的纬度和图像的范围。此外，计算并包含了额外的几何信息（例如足迹和照明角度），并将其纳入图像标签。对于无可用内容（例如完全饱和的图像）的图像则从数据集中剔除。如需完整信息，请参阅实际数据。[信息截断，请参阅实际数据以获取完整内容]
