The Implement of Parcel Sea Map Automatic Mapping Algorithm
Abstract:
Parcel Sea Map mapping is currently implemented by manual, which causes the task tedious and error prone. To overcome this problem, this paper proposes an automatic mapping method for Parcel Sea Map. The boundary point data are basic mapping elements, which are obtained from sea cadastral survey. The mapping result can be demonstrated by two aspects: convex polygon and concave polygon. For convex polygon, well known left-turn and convex hull algorithms are adopted. For concave polygon, two algorithms are proposed. One is enumeration and the other is cutting algorithm. The above two mapping results can finally be determined by the inspector from sea cadastral survey. Experiments show that Parcel Sea Map automatic mapping can efficiently reduce the manual burden of present mapping.
