Abstract

The dataset encompasses portions of Coos, Curry, Douglas, Jackson, and Josephine Counties.The bare earth digital elevation model (DEM) represents the earth's surface with all vegetation and human-made structures removed. The bare earth DEMs were derived from LiDAR data using TIN processing of the ground point returns. The DEM grid cell size is 3 international feet. The elevation units are in international feet. Some elevation units have been interpolated across areas in the ground model where there is no elevation data (e.g. over water, over dense vegetation).WSI collected the LiDAR and created this data set for the Oregon Department of Geology and Mineral Industries (DoGAMI).

Distribution Information

  • Create custom data files by choosing data area, product type, map projection, file format, datum, etc.

  • GeoTIFF

    Simple download of data files.

Access Constraints:

None

Use Constraints:

In some areas of heavy vegetation and forest cover, there may be relatively few ground points in the LiDAR data. TINing the points produces large triangles and hence the elevations may be less accurate within such areas. In some areas with large bodies of water, competing water surface levels may be visible. This is due to seasonal water level fluctuation and intervals of time between acquisition of an area.

Data Quality

Horizontal Positional Accuracy:

Within 30cm based on sensor specifications.
Vertical Positional Accuracy:

The Root Mean Square Error (RMSE) of the data set is 0.05 meters. Accuracy was assessed using 19,453 ground survey (real time kinematic) points. These ground survey points are distributed through out the OLC Rogue River study area. See LiDAR data report.; Quantitative Value: 0.05 meters, Test that produced the value: Root mean square error in meters.
Completeness Report:

Lidar data has been collected and processed for all areas within the project study area.
Conceptual Consistency:

LiDAR flight lines have been examined to ensure that there was at least 60% sidelap, there are no gaps between flightlines, and overlapping flightlines have consistent elevation values. Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting. The data was examined at a 1:3000 scale.

Process Steps

Process Step 1

CC ID: 1290100
Description:

Acquisition.

LiDAR data acquisition began March 8, 2012 and was completed August 16, 2012. The survey utilized Leica ALS50 Phase II and ALS60 laser systems mounted in a Cessna Caravan 208B and Partenavia P.38. Near nadir scan angles were used to increase penetration of vegetation to ground surfaces. Ground level GPS and aircraft IMU were collected during the flight.
Process Date/Time: 2012-01-01 00:00:00

Process Step 2

CC ID: 1290101
Description:

Processing.

1. Flight lines and data were reviewed to ensure complete coverage of the study area and positional accuracy of the laser points.

2. Laser point return coordinates were computed using ALS Post Processor software and IPAS Pro GPS/INS software, based on independent data from the LiDAR system, IMU, and aircraft.

3. The raw LiDAR file was assembled into flight lines per return with each point having an associated x, y, and z coordinate.

4. Visual inspection of swath to swath laser point consistencies within the study area were used to perform manual refinements of system alignment.

5. Custom algorithms were designed to evaluate points between adjacent flight lines. Automated system alignment was computed based upon randomly selected swath to swath accuracy measurements that consider elevation, slope, and intensities. Specifically, refinement in the combination of system pitch, roll and yaw offset parameters optimize internal consistency.

6. Noise (e.g., pits and birds) was filtered using ALS postprocessing software, based on known elevation ranges and included the removal of any cycle slips.

7. Using TerraScan and Microstation, ground classifications utilized custom settings appropriate to the study area.

8. The corrected and filtered return points were compared to the RTK ground survey points collected to verify the vertical and horizontal accuracies.

9. Points were output as laser points, TINed and GRIDed surfaces.
