Introduction. Three dimensional morphology may be used to understand the role of lunar surface dynamic processes. Color and photometric imagery can reveal the chemical, mineralogical, and physical properties of the the lunar soil. Insights into geological stratigraphy and material depositional history may be gained by studying the variation of color andlor photometric properties of the surface with topography. Here we describe two approaches of producing digital terrain models (DTMs) using automatically matched stereo Clementine imagery: (1) an initial, but fast, method that relies upon using approximate camera positions and orientation data, for producing relative height DTMs. (2) a more accurate technique of photogrammetric bundle-block adjustment using ground points for producing absolute height DTMs. It is important to incorporate a DTM into the image rectification process when producing ortho images, else topography may cause localized spatial distortions. Although this effect on Clementine nadir colour imagery is small, it should be taken into account for photometric imaging sequences taken at different viewing angles where surface normals and shading effects are of interest. Color ortho image mosaics and DTMs produced from Clementine imagery are presented and analyzed.
