2009 Federal Emergency Management Agency (FEMA) Topographic LiDAR: Fort Kent, Maine

Dataset Identification:

Resource Abstract:
Camp Dresser McKee Inc. contracted with Sanborn Map Company to provide LiDAR mapping services for Fort Kent, Maine. Utilizing multi-return systems, Light Detection and Ranging (LiDAR) data in the form of 3-dimensional positions of a dense set of mass points was collected in spring 2009 for 187 square miles along the St. Johns River and the Fish River. The Leica ALS-50 LiDAR system was used to collect data for the survey campaign. The nominal point spacing of this data set is 1.4 meters. Leica ALS-50 LiDAR System Acquisition Parameters: Average Altitude: 1400 Meters above ground level Airspeed: ~120 Knots Scan Frequency: 36 Hertz Scan Width Half Angle: 20 Degrees Pulse Rate: 76,200 Hertz

Use limitation statement:
These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.

Resource lineage description
AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description  Lidar acquired and processed to meet 1m (RMSE) horizontal accuracy.
AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy
measure Description  Units in meters. Horizontal point accuracy is a function of angular origination of the pulse; IMU orientation; the scanner encoder and ranging function and will vary depending on the proposed point density selected for the collection. Statistically, the error is roughly 1/3 of the illuminated foot print on the ground and is a function of the beam divergences.
Quantitative Result
result value 1.0
value Units
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description  The vertical accuracy is based on the Sanborn independent collection of 20 ground survey points distributed throughout the project. The fundamental vertical accuracy at 95 percent confidence level in open terrain tested 0.07 meters.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy
measure Description  Units in meters. Based on the vertical accuracy testing conducted by Sanborn using NSSDA and FEMA methodology, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600.
Quantitative Result
result value 0.185
value Units
Completeness Commission
evaluation Method Description  A visual qualitative assessment was performed in the source Lidar dataset. Small data voids were noted by NOAA CSC in tiles 1275-16750 and 1225-17000, these voids are over water and should not impact the quality of the data set.
ConceptualConsistency
measure Description  Data covers the tile scheme provided for the area of interest.
