The invention provides a remote sensing image display method, which comprises the following steps: extracting a plurality of feature points from global basic tile data of the digital earth to obtain a control point library, the feature points having the maximum gray variance in a preset range, and the control point library comprising control point pictures; searching the control point library to obtain a control point set in the range of the to-be-corrected image; according to the control point set, carrying out gray template matching on the control point picture and the to-be-corrected image to obtain a homonymy point set in the to-be-corrected image; according to the homonymy point set, a polynomial model is adopted to carry out block correction on the to-be-corrected image, and three-dimensional graph vertexes corresponding to angular points of each sub to-be-corrected image are obtained; and performing texture mapping display on the corrected to-be-corrected image by adopting a three-dimensional graphic d
