DOGAMI leads the Oregon Lidar Consortium, which was created in 2007 with the goal of providing high-quality lidar data coverage for the entire state. An initial $2 million seed capital investment by the Oregon Legislature has since been leveraged into more than $19 million of lidar acquisition.
Lidar Projects
Since 2008, DOGAMI has ordered 72 lidar flights, supported by funding from more than 80 partners. High-resolution lidar data has been acquired for almost 46,886 square miles in Oregon—approximately 48 percent of the state and about 98 percent of Oregon’s populated areas.
Projects start with a partner interested in funding a specific area, and DOGAMI then works to enlarge that area by finding additional partners and adding consortium funds to create contiguous blocks of lidar collection.

Lidar in Action: Portland Metro Area Project. A 2014 $951,000 project collected 976 square miles of lidar data and orthophotos in the Portland area. Ordering individual flights would have cost nearly $6 million, according to calculations by project partner Metro. The more than 30 partners – including cities, counties, transportation agencies and the U.S. Geological Survey – have access to all the data. Partners are putting the lidar to many uses, from helping 9-1-1 dispatchers have up-to-date information for first responders to inventorying buildings to surveying urban tree canopy.
How Lidar is Collected
Airborne lidar uses a laser range finder mounted in a precisely navigated aircraft to scan the earth's surface at very high rates and collect very dense clouds of X-Y-Z coordinates. OLC projects are collected by Quantum Spatial, Inc. of Corvallis, Ore.
Amendment 8 to Agency-Specific Price Agreement 7525 provides detailed technical specifications and information on optional lidar services.

Technical Specifications
DOGAMI requires aggregate design multi-swath density of at least 8 pulses per square meter. The higher-than-typical density is absolutely necessary to get accurate bare earth coverage in a state that’s as forested as Oregon. The Agency also has a four-point quality control program in place that stringently reviews specifications for data completeness, swath to swath data consistency, digital elevation model requirements, and absolute accuracy of bare earth DEMs. Current technical specifications include:
Acquisition |
Value |
On-ground Spot Diameter | 15 cm - 40 cm measured at 1/e. (note 1) |
Number of Returns per Laser Puls | e ≥ 4 |
Intensity Record Range | 16 Bits |
Laser Scan Angle | ≤ +/- 15 degrees (note 2) |
Planned Survey Sidelap | ≥ 50% Sidelap of adjacent swath (note 3) |
Aggregate Pulse Density | ≥ 8 (note 4) |
Point Dilution of Precision (PDOP) | ≤ 3.0 |
Satellites in View | ≥ 6 |
GPS Stationary Reference Receiver | ≥ 2 receivers, each at least 2 hours long |
GPS Stationary Reference Receiver Sample Rate | ≥ 1 hertz (Hz) |
Aircraft GPS Sample Rate | ≥ 2 hertz (Hz) |
Differential GPS baseline distance | ≤ 30 km |
Ground Control Point (GCP)⁵ [note 5] Accuracy | ≤ 1.5 cm RMSE (note 6) |
Data Quality Value |
Value |
Single Swath Vertical Departure from Planarity | ≤ 5 cm RMSE per 100 m² |
Swath to Swath Reproducibility | ≤ 10 cm RMSE |
Fundamental Vertical Accuracy of Lidar Ground Points | ≤ 9.25 cm RMSE |
Absolute Accuracy of Digital Elevation Models | ≤ 9.25 cm RMSE |
Data Coverage | No voids |
Swath Overlap | ≤ 10% no-overlap area per project area |
DEM and DSM Surface Raster | no voids or artifacts (note 7) |
Aggregate First Return Point Density | ≥ 8 pulse per square meter |
Notes: |
1 – 1/e is defined as the diameter at which the beam irradiance (intensity) has fallen to 36.5 percent of its peak value
2 – Laser scan angle cannot exceed 30 degrees overall 3 – Survey must be designed for 100% double coverage 4 – pertains to the area of each swath with a scan angle between 2 and 12 degrees left and right from nadir 5 – GCPs will be sued for survey calibration and assessment of absolute vertical accuracy 6 – Root Mean Square Error 7 – Determined by DOGAMI and lidar vendor |
Project Reports
-
Data survey reports are provided by the vendor and generally contain a project overview as well as aerial acquisition, ground survey, accuracy, and density information.
-
Data acceptance reports contain a description of the project area, data completeness and control checks, quality consistency results, and absolute accuracy analysis.
These reports are also linked from project area layer popups in the
data viewer
Notes: Some report PDF file sizes are very large.
