ACCURACY COMPARISON ON CULVERT-MODIFIED DIGITAL ELEVATION MODELS OF DSMA AND BA METHODS USING ALS POINT CLOUDS

Accuracy Comparison on Culvert-Modified Digital Elevation Models of DSMA and BA Methods Using ALS Point Clouds

High-resolution digital elevation models (HR-DEMs) originating from airborne laser scanning (ALS) point clouds must be transformed into Culvert-modified DEMs for hydrological and geomorphological analysis.To produce a culvert-modified DEM, information on the locations of drainage structures (DSs) (e.g., bridges and culverts) is essential.Neverthele
