This document proposes a method for automatically constructing coverage catalogues of ASTER satellite images for urban areas around the world. It describes needing high-resolution global urban maps and how ready catalogues of satellite images for cities could promote urban studies. The method uses ASTER satellite metadata to develop catalogues for 3372 cities, combining images through automated algorithms. While accurate, pixel-level cloud assessment could improve results by allowing consolidation of segmented images into complete coverage.
