i17 Delta Levees Centerlines 2017

Once the levee anatomy was created and accepted, the Esri geoprocessing tool "Polygon to Centerline" was used to create a levee crown centerline. From there, the centerlines were merged by LMA, with a single line for each LMA. After the centerlines were accepted and any errors fixed, the centerlines were split by reach and attribute fields (such as project or non-project).

This data depicts the levee anatomy at the time of the LiDAR survey (2017) and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was created and some parts of this data may no longer represent actual surface conditions. This data is an update to the previous Atlas dataset with Delta Levee Centerlines, derived from the 2007 Delta LiDAR.
