摘　　要：卫星影像具有实效性强,获取时间快,覆盖广,成本低等特点;随着社会经济的发展,对地形图的实效性提出更高要求,文中以WordView卫星影像在甘肃礼县测区1:10000基础测绘中的应用为例,对如何利用0.5m卫星影像获取空三成果进行了研讨。研究表明:卫星影像完全能满足1:10000基础测绘内业航测要求。Satellite imagery had the characteristics of high effectiveness,fast acquisition time,wide coverage and low cost. With the development of social economy,higher requirements were put forward for the effectiveness of the topographic maps. Taking the application of WordView satellite imagery in 1:10000 basic surveying and mapping in Lixian Surveying Area of Gansu Province as an example,in this paper, how to use 0.5M satellite imagery to obtain aerial triangulation results was discussed. The research showed that the satellite image could fully meet the requirement of 1:10 000 basic surveying and mapping.
