将真实的遥感影像图片同传统的矢量数字地图有机地结合在一起，制作成清晰直观的影像数字地图，已经成为现今GIS系统开发的一种趋势，但专业的影像数据购买费用昂贵，大大提高了系统开发成本。现提出一种从Google Earth平台中快速提取免费的、高分辨率的遥感影像图片的方法，利用矢量数字地图中的电子地理信息对影像图片进行地图校正和信息补充，能构成一幅完整的影像数字地图，降低开发成本，提高了GIS系统的真实性、直观性和实用性。

Reasonably combinating the real remote sense image with the traditional vector digital map to make the sharp and intuitive image digital map is already a great tendency to GIS system development at present .However , it is greatly improving the system development cost because the professional image data are very expensive .The paper presents a method of quickly and free obtaining remote sense image from Google Earth , using vector digital map ’ s geographic information on revising and supplying the remote sense image constitutes a complete image digital map .It can reduce system development costs and improve the GIS system of authenticity , intuitive and practical .
