A GIS Compilation of Vector Shorelines Derived from Aerial Imagery for the Grand Bay Region of Mississippi and Alabama: 2010 and 2012

This data release features two digitized historical shorelines for the Mississippi (MS) and Alabama (AL) coastline (Pascagoula, MS to Point aux Pins, AL) from 2010 and 2012. The shorelines were heads-up digitized using ArcMap 10.3.1 from 0.5-meter (m) resolution orthorectified aerial photos sourced from the City of Mobile, Alabama (http://maps.cityofmobile.org/gis/gisdata_order.aspx) and 1-m resolution orthorectified aerial photos sourced from the National Agriculture Imagery Program (https://gdg.sc.egov.usda.gov/). These shoreline datasets are suited for long-term shoreline and wetland analyses and physical change assessment.
