| 摘 要： | In this paper,factors lead to changes ande what changes should be considered are firstly discussed.then changes to be represented by set theory is given.Twelve basic change types are described in detail.At last the paper points out that the change between geoobjects and pixels in images is not all corresponging and it causes the difficulty of accurate and robust change detection techniques.

| Abstract: | In this paper,factors lead to changes and what changes should be considered are firstly discussed.Then changes to be represented by set theory is given.Twelve basic change types are described in detail.At last the paper points out that the change between geo_objects and pixels in images is not all corresponding and it causes the difficulty of accurate and robust change detection techniques. |
