Data_Quality_Information:
Logical_Consistency_Report:
Data was verified for correct topology (no intersection, overlap or dangles). Dewberry performed a full qualitative review of the contour data for smoothness and consistency of feature codes.
Completeness_Report:
A visual qualitative assessment was performed to ensure the data completness.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The 3D breaklines inherit the accuracy of the Lidar it was acquired from. Lidar source compiled to meet 1m horizontal accuracy.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 1 meter
Horizontal_Positional_Accuracy_Explanation:
Dewberry does not perform independent horizontal accuracy testing on the LiDAR. LiDAR vendors perform calibrations on the LiDAR sensor and compare data to adjoing flight lines to ensure LiDAR meets the 1 meter horizontal accuracy standard at the 95% confidence level. Please see Appendix D, the LiDAR Processing Report, of the MTS Report for more details.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The 3D breaklines inherit the accuracy of the Lidar it was acquired from.
Quantitative_Vertical_Positional_Accuracy_Assessment:
Vertical_Positional_Accuracy_Value: 0.51 feet
Vertical_Positional_Accuracy_Explanation:
Based on the vertical accuracy testing conducted by Dewberry, using NSSDA and FEMA methodology, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600. The dataset for St. Johns River Water Management District satisfies the criteria: Lidar dataset tested 0.51 ft vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz (0.26 ft) x 1.9600. Lidar dataset tested 0.88 ft vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz (0.45 ft) x 1.9600.
Based on the vertical accuracy testing conducted by Dewberry, using NDEP and ASPRS methodology, consolidated vertical accuracy at the 95% confidence level is computed using the 95th percentile method. The dataset for St. Johns River Water Management District satisfies the criteria: Lidar dataset tested 1.00 ft vertical accuracy at 95% confidence level in all land cover categories combined.

Process_Description:
The ABGPS, IMU, and raw Leica ALS50 LiDAR data are integrated with Leica's Incorporated's ALS Post Processor software. The resultant file is in a LAS binary file format . The LAS file version 1.1 format can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 HARN horizontal datum and NAVD88 vertical datum. The date and time for each flight line can be determined using the Julian date and time. The Julian date is a continuous count of days and fractions since noon Universal Time on January 1, 4713 BCE on the Julian Calendar.

Process_Description:
The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters are applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.1 format. The header file for each dataset is complete as define by the LAS 1.1 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground Class 7= Noise Class 9 = Water Class 12= Overlap

Process_Description:
Vector 3D breaklines were captured utilizing MARS proprietary software. Merrick uses a methodology that directly interacts with the LiDAR bare-earth data to collect drainage breaklines. To determine the alignment of a drainageway, the technician first views the area as a TIN of bare-earth points using a color ramp to depict varying elevations. In areas of extremely flat terrain, the technician may need to determine the direction of flow based on measuring LiDAR bare-earth points at each end of the drain. The operator will then use the color ramped TIN to digitize the drainage centerline in 2D with the elevation being attributed directly from the bare-earth .LAS data. Merricks proprietary MARS software has the capability of flipping views between the TIN and ortho imagery, as necessary, to further assist in the determination of the drainage centerline. All drainage breaklines are collected in a downhill direction. Roads are captured in 2d using the imagery and then draped on the lidar elevation surface. Softfeatures are captured using the lidar elevation surface. Waterbodies are captured by finding the lowest elevation around a feature and using that as the base elevation for the water body. The features generated in MARS are then output to a Microstation .dgn file. The .dgn file is then imported into the appropriate feature class and the topology rules are validated.
