Breton Island Transects with Shoreline Change Rates (Pre/Post Hurricane Katrina) (Geographic, NAD83)

Breton Island, Louisiana Transects with Shoreline Change Rates (Pre/Post Hurricane Katrina) (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岸线变化率断面数据集（卡特里娜飓风前后）（地理坐标系：NAD83）包含源自数字岸线分析系统（Digital Shoreline Analysis System，DSAS）4.0版本的矢量断面数据。研究人员将DSAS统计输出表格中的岸线变化率数据与各断面进行关联，以实现逐断面的岸线变化率可视化展示。
