Theme keywords: LiDAR, LAS, Orthophotography

Abstract: This dataset is part of a regularly scheduled update of LiDAR and digital orthotography products. The dataset was created from source imagery acquired by a Trimble TAC80 natural color digital camera and LAS data acquired by a Optech ALTM HA500 (Pegasus) LIDAR sensor from January 18, 2015 to February 5, 2015.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
Verification of attribute accuracy for LiDAR data involves the use of filtering techniques. Auto-filtering uses algorithms to reclassify data in the point cloud. Hand-filtering involves the analysis of a technician working in a graphic environment to reclassify the erroneous points that may remain in the LiDAR point cloud after auto-filter.

Logical consistency report:
Calibrations of the LiDAR flightline data are performed; this process is known as boresighting. The flightlines are compared to evaluate both their relative and absolute accuracies.

Completeness report:
The dataset was reviewed to ensure completeness and accuracy.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Half-foot (0.5') pixel ortho imagery meets a horizontal accuracy (Accuracyr) of 3.8 feet at 95% confidence interval [2.2 feet RMSEr] as specified in the Federal Geographic Data Committee's (FGDC) Geospatial Accuracy Standards, Part 3: National Standard of Spatial Data Accuracy (NSSDA

Quantitative horizontal positional accuracy assessment:
Horizontal positional accuracy value: .28 feet
Horizontal positional accuracy explanation:
RMSE(r)

Ground Control
Source contribution:
Horizontal and vertical control was used to establish positions and elevations for reference and correlation purposes and as input to the aerotriangulation process. Control consists of Airborne GPS/IMU and ground control points for ground reference.

Process step:
Process description:
The digital orthophotography was rectified from the digital aerial photography. The orthoimagery was rectified to the DTM data and aerotriangulation results using Cubic Convolution methodology. The ortho imagery was mosaicked and radiometrically balanced to ensure tonal consistency. The final pixel resolution is half-foot (0.50'). Said orthoimagery meets National Map Accuracy Standards.
