Breton Island Transects with Shoreline Change Rates (Pre-1950s) (Geographic, NAD83)

Breton Island, Louisiana Transects with Shoreline Change Rates (Pre-1950s) (Geographic, NAD83) consists of vector transect data that were derived from the Digital Shoreline Analysis System (DSAS) version 4.0. Rates from the DSAS statistical output table were joined to the transects to provide a visual representation of the shoreline change rates on a transect-by-transect basis.路易斯安那州布雷顿岛1950年代前岸线变化率断面数据集（地理坐标系：北美大地基准83（North American Datum 83，NAD83））由源自数字岸线分析系统（Digital Shoreline Analysis System，DSAS）4.0版的矢量断面数据构成。该数据集将DSAS统计输出表格中的岸线变化率数据与各断面进行关联，以此实现逐断面形式的岸线变化率可视化展示。
