HRSC-AX data products (DEM and multi channel) from aerial overflights in 2008 over Bayelva (Brøggerhalvøya peninsula, Spitsbergen).

HRSC is a multisensor pushbroom instrument with 9 CCD line sensors mounted in parallel that has been in orbit around Mars since January 2004 on ESA’s Mars Express spacecraft (Gwinner et al., 2016). It simultaneously obtains high-resolution stereo, multicolor, and multiphase images. Digital photogrammetric techniques are used to reconstruct the topography on the basis of five stereo channels, which provide five different views of the ground.

HRSC（High Resolution Stereo Camera，高分辨率立体相机）是一款多传感器推扫式仪器，搭载9台并行安装的CCD线阵传感器，于2004年1月随欧洲空间局（ESA，European Space Agency）的火星快车号（Mars Express）航天器进入火星轨道（Gwinner等，2016）。该仪器可同步获取高分辨率立体、多色及多相位影像。研究人员依托其配备的五个可提供五种不同地面观测视角的立体通道，结合数字摄影测量技术完成了火星地形的重建。
