This data will be used by the USDA and/or USACE to generate contours for use in hydraulic/hydrologic model development, and for assessing environmental impacts. An ESRI shapefile showing the project sites, square miles, and deliverables has been provided to Sanborn. LIDAR was collected on average of 2 meter point spacing and vertical accuracy of 15 centimeters on bare, flat ground was required. The project area was flown in May, 2005. Purpose: This LIDAR operation was designed to provide a dense set of masspoints within the defined areas. The data sets are suitable for the development of contours for use in hydraulic/hydrologic model development, and for assessing environmental impacts. . Supplemental_Information: This data set is accompanied by an associated metadata record.

Data_Quality_Information: Attribute_Accuracy Attribute_Accuracy_Report: LIDAR Bare Earth data were compared with airport surveyed elevations provided by Kinematic survey. The data and survey were compared and verified per project specifications Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: <= 15cm Attribute_Accuracy_Explanation: RMSE (cm) of bare earth LIDAR points compared with kinematic survey checkpoints. Logical_Consistency_Report: Data were filtered using automated procedures followed by manual editing to remove points that did not belong to the terrain surface (e.g. water, vegetation, buildings, system noise). Completeness_Report: The bare earth surface may contain voids where insufficient energy was reflected from the surface to generate a valid return from the terrain. Voids in the bare earth surface tend to occur in heavily vegetated areas, water bodies, and beneath buildings, motor vehicles, bridges, etc. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: LIDAR Bare Earth data were compared with airport surveyed elevations provided by Kinematic survey.
