WSI collected Light Detection and Ranging (LiDAR) data for the Oregon LiDAR Consortium (OLC) Clackamol 2013 study area in Clackamas and Marion County, Oregon. The collection of high resolution geographic data is part of an ongoing pursuit to amass a library of information accessible to government agencies as well as the general public. The study area is predominantly comprised of rural and forested lands, including the Clackamas River, Timothy Lake, and Silver Creek Reservoir.
Between May 1 and May 6, 2013 and again between July 8 and July 20, 2013, WSI employed remote-sensing lasers in order to obtain a total area flown of 80,504 acres. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter. Three delivery areas totaled 443,535 acres. The LiDAR survey utilized a Leica ALS60 mounted in a Cessna Caravan 208B. The systems were programmed to emit single pulses at around 100 kHz and flown at 900 m AGL, capturing a scan angle of 15 degrees from nadir. These settings were developed to yield points with an average native density of greater than eight pulses per square meter over terrestrial surfaces.
Final products included lidar point cloud data, one-meter digital elevation models of bare earth ground model and highest-hit returns, intensity rasters, study area vector shapes, and corresponding statistical data. Final deliverables were projected in Oregon Statewide Lambert Conformal Conic. This metadata was created for the bare earth digital elevation models.

Data Quality
Horizontal Positional Accuracy: |
unknown |
---|---|
Vertical Positional Accuracy: |
Vertical accuracy statistical analysis uses ground survey points in open areas where the LiDAR system has a "very high probability" that the sensor will measure the ground surface and is evaluated at the 95th percentile. For the OLC Clackamol study area, a total of 6,708 RTK points were collected. No independent survey data were collected, thus statistics are "Compiled to Meet". For more information about the vertical accuracy, please refer to the final report, listed above in the Supplemental_Information field of this metadata record. ; Quantitative Value: 0.03 meters, Test that produced the value: Compiled to meet root mean square error. |
Completeness Report: |
Lidar data has been collected and processed for all areas within the project study area. |
Conceptual Consistency: |
Upon receipt from vendor (WSI), all LiDAR data was independently reviewed by staff from the Oregon Department of Geology and Mineral Industries (DOGAMI) to ensure project specifications were met. All data were inventoried for completeness and data were checked for quality, which included examining LiDAR data for errors associated with internal data consistency, model quality, and accuracy. |
Lineage
Process Steps
Process Step 1
Description: |
The LiDAR survey occurred between May 1 and May 6, 2013 and again between July 8 and July 20, 2013 utilizing a Leica ALS60 mounted in a Cessna Caravan 208B. The systems were programmed to emit single pulses at around 100 kHz and flown at 900 m AGL, capturing a scan angle of 15 degrees from nadir. These settings were developed to yield points with an average native density of greater than eight pulses per square meter over terrestrial surfaces. |

Process Date/Time: | 2013-01-01 00:00:00 |
Process Step 2
Description: |
The NOAA Office for Coastal Management (OCM) received the files in the proprietary ESRI grid format. The files were converted to floating point GeoTIFF format in vertical meters using gdal_translate from GDAL version 2.1.1. |
---|---|
Process Date/Time: | 2017-05-01 00:00:00 |
Process Step 3
Description: |
Files were reorganized as cloud optimized geotiffs to support streaming and the vertical units were reverted to feet to match the horizontal units. |
