The invention discloses a feature extraction and generation method of a geographic information image. A geographic information image extraction module and a geographic information image generation module are included. The geographic information image extraction module comprises satellite remote sensing image extraction, unmanned aerial vehicle aerial surveying and mapping and total station field surveying and mapping; the geographic information image generation module is used for establishing raster data for geographic information in a target area and rendering the raster data to obtain a geographic information image in the target area; the geographic information image extraction module and the geographic information image generation module are connected through a computer to form signal transmission. A local geographic information picture of the region can be obtained by selecting raster data in the corrected two-dimensional geographic information space library, and the generated two-dimensional geographic information space library and the three-dimensional model are compared for use, so that the display force of the geographic information picture can be enhanced, and the use of workers is facilitated.
本发明公开了一种地理信息图像的提取特征与生成方法,包括地理信息图像提取模块和地理信息图像生成模块;地理信息图像提取模块包括卫星遥感影像提取、无人机航拍测绘和全站仪实地测绘;地理信息图像生成模块包括对目标区域内的地理信息建立栅格数据、对栅格数据进行渲染得到目标区域内的地理信息图像;所述地理信息图像提取模块和地理信息图像生成模块之间通过计算机连接,形成信号传输,通过在改正后的二维地理信息空间库内选取栅格数据,可以得到一张该地区局部的地理信息图片,通过将生成二维地理信息空间库和三维立体模型对照使用,可以增强地理信息图像的展现力,便于工作人员的使用。
