The invention discloses an intelligent path selection method and system based on satellite remote sensing image feature analysis. The method comprises the steps of correcting and fusing at least two pieces of remote sensing image data for a selected path according to an atmosphere, geometry, radiation and spectral consistency correction method, and generating multisource remote sensing image data;conducting superposition on the multisource remote sensing image data and a digital topographic map to generate an ortho-photo map; establishing a digital elevation model (DEM) by conducting preprocessing pretreatment, initialization, triangle connection and triangle optimization on the ortho-photo map; extracting ground surface object information from the ortho-photo map based on a multispectralremote sensing data ground surface information automatic extraction method and classifying the ground surface object information; integrating the digital elevation model (DEM) and the ground surfaceobject information with a geographic information system (GIS) , and determining an optimized path of a power transmission cable in the integrated geographic information system by adopting a space analysis method.
