基于AutoCAD的天地图影像加载方法OA

In recent years,with the improved updating efficiency of remote sensing data,it is feasible to obtain continuously updated large-scale Gaussian projection images of urban areas based on Tianditu.To achieve fast and accurate loading of remote sensing images in drawing scenes,according to the idea of slicing the Gaussian projection images of urban areas,storing them regularly,and then loading the images according to the range,the corresponding tool software for image processing and image loading was developed.A method of loading images from Tianditu based on autodesk computer aided design(AutoCAD)was proposed,which has been successfully applied to multiple urban planning and design projects in Jinan City.The method did not rely on professional geographic information system(GIS)software and could run in a stand-alone environment.It improved the efficiency of using the remote sensing image from Tianditu in the field of urban planning and expanded the application scene of data from Tianditu.
