Description:

Abstract:

Provides topographic point data of levees and surrounding terrain

Purpose:

This data set was developed to present topographic point data of the post-failure condition of levee failures in New Orleans, Louisiana following Hurricane Katrina. The data sets can be used by engineers, scientists, and GIS specialists to inform public officials, policy makers, and the general public.

Supplemental_Information:

Additional information about the field activities from which this data set was derived are available online from the USGS Coastal and Marine Geology InfoBank at <http://walrus.wr.usgs.gov/infobank/n/no105la/html/n-o1-05-la.meta.html> and at <http://walrus.wr.usgs.gov/infobank/n/no106la/html/n-o1-06-la.meta.html>.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Lidar-derived points are accurate to between 11 and 164 centimeters depending on the particular data set.

Logical_Consistency_Report:

Point data has been visually examined and compared to other data sets of the area to assure logical consistency.

Completeness_Report:

Ommissions and gaps in data reflect data out of view or range of the laser scanner at time of data acquisition.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Lidar-derived points are accurate to between 11 and 164 centimeters, measured as three-dimensional error. This includes 2.5 cm laser error, between 7.2 and 16.3 cm registration error, and between 3.1 and 163.5 cm georeferencing error.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Lidar-derived points are accurate to between 11 and 164 centimeters, measured as three-dimensional error. This includes 2.5 cm laser error, between 7.2 and 16.3 cm registration error, and between 3.1 and 163.5 cm georeferencing error.

Lineage:

Process_Step:

Process_Description:

The terrestrial lidar data was collected from between 7 and 28 scan locations at each site. Each scan location within a single site was registered to a neighboring scan location within the same site with overlapping data. All scan locations were georeferenced to GPS- surveyed coordinates from each location that formed visible features within the point cloud data. The data was filtered only for stray returns from atmospheric dust, moisture, birds, etc. and anomolouos reflections from water.
