Real 3D project--Susong
Jul 26, 2023
In the comprehensive service construction project of geographic mapping in Susong County, Anhui Province, HD image data of 2370 square kilometers of Susong County were obtained by means of 450-million-pixel digital aerial camera and laser radar aerial camera with laser emission frequency up to 2000KHz. Combined with the high-precision digital elevation model, a whole-area terrain level 3D model of large scenes was constructed, and the pilot test of county-level 3D model was realized by implementing the UAV oblique aerial photography of key areas in Susong County, providing a three-dimensional and intuitive decision-making basis for the delineation of the three districts and three lines, territorial spatial planning and county fine management.

Connotation of Real Scene 3D Data
The three-dimensional world is different from the two-dimensional world: the two-dimensional world is a flat world with only length and width, while the three-dimensional world is a three-dimensional world with length, width and height, which is also the space in which we humans live. More >
