Abstract: A Topographic map contains three kinds of information:featureshorizontal and elevation data。According to cartographic requirements,this paper has analysed the specialities of space photogrammetric imagingsystems,photogrammetric practice and efficiency.It is proved that thespace photogrammetric mapping has the advantages of high speed of cove-raging an area,relatively low cost,easy to obtaining topographic details,espe-cially in inaccessible areas;and it can be applied in topographic mappimg at1:50000—1:100000 scales.Space photography and its application is of broadprospect.
