Title: 2010 Oregon Department of Geology and Mineral Industries (DOGAMI) Lidar: Klamath Study Area
Short Name: or2010_dogami_klamath_m1410_metadata
Status: Completed
Publication Date: 2012

The Oregon Department of Geology & Mineral Industries (DOGAMI) contracted with Watershed Sciences, Inc. to collect high

resolution topographic LiDAR data for multiple areas within the State of Oregon. The areas for LiDAR collection have been designed

as part of a collaborative effort of state, federal, and local agencies in order to meet a wide range of project goals.

This LiDAR data set was collected over six deliveries from September 14 through October 27, 2010 and encompasses portions of Klamath

and Lake counties in Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.61 pulses

per square meter over terrestrial surfaces. The area of interest (AOI) totals 1054 square miles (674,756 acres) and the total area

flown (TAF) covers 1083 square miles (692,999 acres). The TAF acreage is greater than the original AOI acreage due to buffering

and flight planning optimization. This metadata record reflects all the data and cumulative statistics for the overall lidar survey.

In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. Elevation values

for open water surfaces are not valid elevation values because few LiDAR points are returned from water surfaces. LiDAR intensity

values were also collected.

Dates of acquisition for the six deliveries that make up this data set.

Data Quality

Horizontal Positional Accuracy:

Not specified in final report, assumed to be 1 m.

Vertical Positional Accuracy:

The Root Mean Square Error (RMSE) of the data is 0.03 meters (0.11 ft). Accuracy was assessed using 6,862 ground survey (real time

kinematic) points. These ground survey points are distributed throughout the OLC Klamath study area.

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 50 percent 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 were examined at the 1:3000 scale.


Process Steps

Process Step 1

CC ID: 1049781

No metadata for the lidar point data was provided to NOAA OCM with this data set. The following process step contains information

derived from the metadata record for the DEM (Digital Elevation Model), which is a product of the lidar point data, and the Watershed

Sciences, Inc. lidar report. This lidar report may be accessed at:


1. Lidar data acquisition began September 14,2010 and was completed October 27, 2010.

2. The survey used both a Leica ALS50 Phase II and a Leica ALS60 laser system mounted in a Cessna Caravan 208B.

3. Near nadir scan angles were used to increase penetration of vegetation to ground surfaces.

4. Ground level GPS and aircraft IMU were collected during the flight.


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

Process Date/Time: 2010-01-01 00:00:00

Process Step 2

CC ID: 1049782

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained LiDAR

elevation and intensity measurements. The data were in OGIC HARN, Oregon Statewide Lambert Conformal Conic Projection (NAD83/HARN),

NAVD88 (Geoid03) vertical datum and International Feet. OCM performed the following processing for data storage and Digital Coast

provisioning purposes:

1. The data were converted from OGIC HARN, Oregon Statewide Lambert Conformal Conic Projection (NAD83/HARN) to geographic coordinates.

2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid03.

3. The data were converted from International Feet to meters.

4. The data were sorted by time and zipped to laz format.
