EDGE BASED METHOD FOR LEVEE MAPPING USING LIDAR DATA AND ORTHOPHOTOGRAPH

摘要

The present invention relates to a method for mapping edge-based levee lines using light detection and ranging (LiDAR) data and orthophotograph and, more specifically, to a method for mapping edge-based levee lines using LiDAR data and orthophotograph wherein the edge-based levee lines are extracted using the orthophotograph, and in an area where edge-based levee lines are not extracted, LiDAR-based levee lines extracted using the LiDAR data are connected to complete the levee lines. [Reference numerals] (AA) Start; (BB) End; (S10) Generate LiDAR-based levee lines; (S20) Emphasize images; (S30) Extract edges; (S40) Generate edge-based levee lines; (S50) Connect levee lines
