Abstract: Aiming at the difficulty of refined 3D modeling data acquisition and product production technology in typical overseas regions, this paper designs a high-resolution optical satellite image refined 3D modeling method. In this method, the central area of Dubai is selected as the experimental area. High-resolution satellite image data such as WorldView-3 and GeoEye-1 are selected as the main data source, and multi-source image downloading from internet is used as the auxiliary data.The method uses accurate orientated refined RPC parametersand the precise geometric information (DEM/DOM) to complete 3D model production of the main buildings in the area, and forms a high-resolution satellite image 3D modeling prototype system, which meets the needs of the accuracy and fineness requirements of quickly produce 3D digital models production in global geographic information resource construction projects.

Key words: 3D modeling, monomerization, high-resolution satellite image, multi-source image online, global geographic information resource construction
