摘要：In this paper we will revise the recent developments in the field of automatic object extraction for change detection and GIS update under different aspects: (1) level of automation; (2) available sensors and image characteristics; (3) effectiveness and processing time; and (4) verification/editing and quality of results. For most applications, none of these aspects can be considered isolated from the others. We will exemplify the importance of these aspects by the recent efforts made, in order to support the management and prevention of natural hazards and civil crises, e.g. caused by floodings or earthquakes
