Abstract：Research purposes: During application of remote sensing technology in the railway engineering geological investigation，due to the particularity of geological phenomena and the complexity of interpretation environment，the uncertainty with multiple annotations happens to interpretation of the information on the engineering geological characteristics，and it seriously influences the interpretation quality of remote sensing image．Through quantitative analysis of image spatial resolution．mapping scale and interpretation precision and f．actors evaluation of interpretation quality，the mathematical relations are obtained between the image spatial resolution and the mapping scale and between the image spatial resolution and interpretation precision of remote sensing image．
Research conclusions: The image spatial resolution is an important index for the accuracy of image interpretation．Under condition a mapping scale is given，the most suitable resolution of remote sensing images call be calculated，and a topographic map scale M Can be obtained for correcting the remote sensing images．Its mathematical relationship is R={ (L*M)/2 -Rmin}．1he image ground resolution Rc is the key factor for evaluation of image quality and with it，the accuracy of remote sensing interpretation(engineering geological characteristic point P，line P’and area P”)can be 1一calculated．Its mathematical relationship is RG=3P’=P”/3=2a。
