Zusammenfassung: | The invention discloses a method for generating ground object filing data of a remote sensing image. The method comprises the following steps of: performing weight assignment on ground objects after crowdsourcing geographic information data preprocessing from large to small according to importance degrees; searching all orientation indicators in a buffer area of a ground object to be archived in the remote sensing image, and determining a final orientation indicator of the ground object to be archived in the searched orientation indicators; generating a schematic diagram of the ground object to be archived and a schematic diagram formed by the ground object to be archived and the final orientation indicator of the ground object to be archived; then, calculating the azimuth angle of the ground object to be archived relative to the final azimuth indicator, and performing semantic description on the relationship information between the ground object to be archived and the final azimuth indicator in combination w |
