Comparison of sealing surface degree assessment based on orthophotomap and lidar data.
The sealing degree of a catchment area, which specifies the part of the total catchment area constituted by an impervious area, is a fundamental parameter determining the structure and outflow time from a catchment area. Recommendations for the piston rod sealing surface assume that typical materials and processes are used to manufacture the piston rod by induction hardening a carbon steel rod, grinding, hard-chromium plating and then polishing it to achieve the specified diameter and finish. Orthophotograph is an accurate representation of the Earth's surface, having been adjusted for topographic relief lens distortion, and camera tilt. Orthophotographs are commonly used in Geographic Information Systems (GIS) as a map accurate background image.
