2012 Digitized Shoreline for Breton Island, Louisiana(Geographic, NAD83)

Shorelines were derived from a U.S. Geological Survey Earth Resources Observations and Science Center (EROS) high-resolution orthorectified image that was collected on October 20, 2012 over Breton Island, Louisiana. Shorelines were digitized in ArcMap 10.2.2 so they could be used for area and shoreline change analysis using the Digital Shoreline Analysis System (DSAS) version 4.0.

本数据集的海岸线提取自美国地质调查局（U.S. Geological Survey）地球资源观测与科学中心（Earth Resources Observations and Science Center，EROS）于2012年10月20日在路易斯安那州布雷顿岛上空采集的高分辨率正射校正影像。所有海岸线均通过ArcMap 10.2.2完成数字化处理，以便借助4.0版数字海岸线分析系统（Digital Shoreline Analysis System，DSAS）开展面积与海岸线变化分析。
