Embodiment Construction
[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0051] Using real DEM data to test the valley ridge line extraction method based on scale space and multi-angle terrain section, the extracted ridge line and valley line are basically consistent with the terrain undulations, which proves that the present invention is correct and effective in theory, and It is also feasible in practical application. The effect is shown in the accompanying drawings, and it can be seen that the ridge lines and valley lines extracted by the present invention have good consistency with the actual topography in both overall and detail.
[0052] The embodiment of the present invention carries out the extraction of ridge line and valley line to the 5m resolution of certain area in Zhejiang Province, the DEM data that size is 1673x1909, refer to figure 1 , the concrete steps of the embodiment of the present invention are as fol...
