STUDY ON VERTEX INTERVAL DETERMINATION FOR CONSISTENT CALCULATION OF COASTLINE LENGTH

Woo, H. S.; Kwon, K. S.; Kim, B. G.

Coastline extraction and decision have important implications for efficient land management and national policy formulation. However, coastlines extracted without certain criteria are difficult to obtain consistent results for the same region, and therefore, have a lot of restrictions on land management and application. For example, in some South Korea coastlines surveyed in this study, it was confirmed that there is a large difference in coastline lengths calculated for the same area depending on how the vertex interval is set. In this study, we propose and discuss the guidelines to enable consistent and accurate coastline extraction for the same area. The consistency of coastline output can be ensured only by the coastline calculation method using vertex interval criterion considering regional and coastline characteristics. This research content is expected to contribute to efficient land management and national policy establishment and progress.
