Abstract: 4D products are basic mode of digitized products that are made by combining model remote sensing with GIS technology, and have already brought everybody’s high recognition. Coal mining makes great destroy to land of coal mining area, and ecological environment becomes worse, therefore land reclamation of mining area has already turned into investigated emphases. 4D meaning is briefly introduced, and its six characteristics are expounded in this paper. Production technique and application status of 4D are summarized, and existed problems are analyzed in developed aspect. Land reclamation of mining area is a complex system engineering, and application of 4D products can be impenetrated in whole process. Otherwise 4D has broad application scope in land management of mining area and mine information construction. Compound of remote sensing and DTM can be apply to solve mine survey, monitor of surface and marginal slope and so on.
Key words: 4D produce； land reclamation； remote sensing image； data resource
