More Information
Summary:The invention discloses a geographic region similarity assessment method based on multi-source data and EMD distance, and the method comprises the steps: obtaining feature data corresponding to a target region and each region to be assessed on geographic region features such as a spatial topological structure and attribute information, and carrying out the standardization of the feature data of each region to be assessed; and then calculating the similarity of the to-be-assessed region on each geographic region feature relative to the target region, and performing weighted fusion on the similarity of each geographic region feature of each to-be-assessed region according to the weight of each geographic region feature to obtain a similarity assessment result of each to-be-assessed region. Meanwhile, the spatial topological structure and the attribute information are considered, full fusion of the spatial topological structure and the attribute information is achieved, the evaluation result is accurate, and the
