摘　　要：随着现代光学卫星成像系统的分辨率不断提升,卫星测绘测绘逐步向定位精细化、功能多样化方向发展。通过对立体成像技术的应用开发,基于GPS卫星定位系统可实现便携式提取地面信息数据,结合辅助测量功能仪器,对高程、点位、面积、距离等信息因素进行高效化提取。通过GPS数据与卫星影像数据转化融合的方式,可实现多样化数据在卫星图像中的特性化显示,构建具有地块信息的信息数据集库,丰富卫星影像在中小比例尺测绘中的使用维度。根据测绘工程中影像挂图制作需求,优化信息的提取方法,从而提高测绘效率并实现信息可视化管理。With the continuous improvement of resolution in modern optical satellite imaging systems,satellite surveying and mapping are progressively evolving towards more precise positioning and diverse functionality.By applying stereo imaging technology and leveraging the Global Positioning System(GPS)for satellite positioning,portable extraction of ground information data can be achieved.In conjunction with auxiliary surveying instruments,this enables efficient extraction of information related to elevation,location,area,and distance.By integrating GPS data with satellite imagery through transformation and fusion,characteristic display of blood vessel data within satellite data can be realized.This approach constructs an information database with parcel information,enriching the application dimensions within small and medium scale satellite imagery.It meets the requirements for image map production in surveying and mapping projects,optimizes the extraction methods for change detection of patches,enhances surveying efficiency,and achieves visual information management.
