ABSTRACT
We produce high-resolution (222 m grid element-1) Digital Terrain Models (DTMs) for Mercury using stereo images from the MESSENGER orbital mission. We have developed a scheme to process large numbers of images (typically more than 6000) by photogrammetric techniques, which include, multiple image matching, pyramid strategy, and bundle block adjustment. In this paper, we present models for map quadrangles of the northern hemisphere H3, H5, H6, and H7. The models are demonstrated to be in excellent agreement with data from MESSENGER’s onboard laser altimeter.
