This volume provides a comprehensive overview of the methodologies, datasets, and approaches related to the use of remotely sensed data to map human settlements at the global scale. The contributors describe the characteristics of human settlements as seen and mapped from remote sensors, either at the regional or global scale. They also discuss the spectral variety, special scales, and nighttime appearance as key remote sensing indicators of these environments. To provide readers with the opportunity to experience the latest tools, the editors supplement the text with a DVD that provides samples of the latest products.
