digital vector data
This delivery contains 2 ft contours of the classified ground surface.
The following are the collection parameters and equipment used to create these data sets.
Aircrafts: Cessna 310(N7516Q), Piper Navajos (N6GR and T73TM), Beechcraft KingAir (N898WW)
Lidar Systems: Optech ALTM Gemini (03SEN145 and 07SEN201)
Approximate Collection Altitude (Above Mean Terrain): 1400 meters
Ground Speed: 150 kts
Pulse Rate Frequency: 70 kHz
Mirror Scan Frequency: 40 Hz
Scan Angle (+/-): 17 degrees
Beam Divergence: Narrow (0.3 mrad)
Accuracy statements are based on areas of moderate terrain, with points classified as ground. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas.
The purpose of this dataset is to provide lidar derived products

Create a smoothed-best estimated trajectory (SBET) of the sensor at a rate of 200 Hz, by integrating the airborne GPS and IMU data The basis of the GPS coordinates were provided to Aero-Metric by Lounsbury, Inc., and were referenced to NAD83 (CORS96) with GEOID09 derived orthometric heights. The maximum baseline distance for this area was 15 km, the average base line length was 5 km. The mean GPS positional accuracy for this area was +/- 0.06 meters.
20110511-20111005
Integrate SBET and raw laser data to produce point cloud data in LAS 1.1 format for each flight line.
20110511-20111005
Data Calibration: An in-situ calibration was performed using the data collect for this project. The data was classified in each line separately for ground and other common features between lines, such as building roofs. This data was processed in TerraMatch 11.001 (TerraSolid, Ltd.), to compute corrections for roll, pitch, heading, and mirror scale. These corrections are applied in order to minimize discrepancies between flight lines.
20110611-20111005
Automated classification of the bare-earth data from the lidar point cloud using a series of algorithms customized for the types of terrain encountered in the project.
20110611-20111010
Manual classification of any data which appears to be properly classified using the automated methods.
