N2 - SMART-1 was the first of a series of Small Missions for Advanced Research in Technology (SMART) created by the European Space Agency (ESA). This first satellite was designed to improve the knowledge about the Moon by pursuing several scientific goals: search for signs of water-ice in craters near the Moon's poles, contribute to clarify the origin of the Moon and reconstruct the evolution of the Moon by mapping its surface distribution of minerals, key chemical elements and topography. In this paper we present SMARTIC, a project that has the goal of constructing a Moon Atlas with the 31947 images captured during the mission by the onboard AMIE instrument, which covered approximately 96% of the Lunar surface. During the earth escape phase, the AMIE CCD was damaged by radiation, producing several unpredicted effects such as an increased dark current and charges accumulation, invalidating the laboratorial flat field correction algorithm. A new image calibration procedure was developed based on the in flight images and on the theoretical models, and is presented in the article. For building the Lunar maps, image mosaicing and projection techniques were used to discard low quality images, compensate the geometrical distortions and compose the calibrated images into a set of 88 maps of the Moon. At the end of the article, a low resolution version of the maps produced is presented and are discussed the main difficulties found in the image processing and future developments and improvements.
