    摘要: Provided are a method and apparatus of filtering geographical data. The method may include selecting a map region to be retrieved, receiving a retrieval object and a retrieval condition, outputting a trapezoidal interface, verifying a threshold corresponding to a height of the trapezoidal interface for each position of the map region, filtering the retrieval object satisfying the threshold or more or less in each position of the map region to extract the filtered object, and displaying the filtered object on the map region to output the displayed object.
