The surface features of the Earth and Moon differ substantially. The detailed
investigation of morphology is one of the foremost science goals of a Japanese
lunar explorer Selenological and Engineering Explorer (SELENE) that will be
launched in 2007. The Terrain Camera (TC), one of the mission instruments
on SELENE, is a panchromatic stereo camera of 10 m spatial resolution from
the SELENE nominal altitude of 100 km. Detailed lunar maps including digital
terrain models (DTMs) will be produced from the TC data. These maps will
be fundamental information for lunar morphology. In this paper, we describe
the TC global high-resolution stereo mapping experiment.

1. Introduction

To provide lunar topographic data is one of the most important sub-
jects of lunar explorations. Contour maps produced using Apollo stereo
imaging data have been fundamental data sets for lunar sciences though
they cover only 20% or less of the surface in the lunar equator regions.
Nearly global (between 75 ◦ in longitude) topographic data for the Moon

were obtained by Clementine lidar with vertical accuracy of 130 m but the
mean distance between its sampling points was considerably large, about
50 km. 1 , 2 Recently, Cook et al. 3 - 5 have produced excellent lunar global
Digital Terrain Models (DTMs) from Clementine UVVIS image data with
spatial resolution of 100-150 m/pixel. Local relative height resolution of
their DTM tiles is within nearly 100 m. On the other hand, Archinal et al. 2
are creating the newest control network, Unified Lunar Control Network
(ULCN) 2005 with horizontal accuracy of a few km, and vertical accuracy of
1 km or less.
