2007 Oregon Parks and Recreation Department Lidar: Rogue River
|
This lidar data set was collected along the Rogue River Greenway and Recreation
Corridor, between TouVelle State Park and downtown Grants Pass in portions of Jackson
and Josephine Counties, Oregon. This data set covers approximately 28,000 acres and
was collected on May 30 and 31, 2007. The lidar data are multiple return and are classified
as unclassified and bare earth. Sky Research, Inc. collected the LiDAR and created
this data set for Oregon Parks and Recreation Department.

Lidar Use Limitation |
These data depict the elevations at the time of the survey and are only
accurate for that time. Users should be aware that temporal changes may
have occurred since this data set was collected and some parts of this data may no
longer represent actual surface conditions. Users should not use this data
for critical applications without a full awareness of its limitations. Any conclusions
drawn from analysis of this information are not the responsibility of NOAA
or any of its partners. These data are NOT to be used for navigational purposes.

Sky Research acquired elevation data using an ALTM 3100 airborne LiDAR
system at an average altitude of 1000 meters and a laser repetition rate of 71 kHz
(71,000 measurements per second). The following were the LiDAR Data Acquisition Parameters:
Scan width: 317 m, Scan Overlap: 50 percent, Scan Frequency: 50 Hz, Scan Angle: plus
or minus 13 degrees, Average spot spacing: 0.54 m, Vertical accuracy: 10 cm, Horizontal
Accuracy: 33 cm. During the data acquisition, the sensor operator observed the real-time
LiDAR swath coverage to assure full coverage for the survey area. The operator also
monitored the in-flight Position Dilution of Precision (PDOP) and GPS satellite coverage.
If tolerance thresholds of either were exceeded, data acquisition activities were
put on hold until acceptable conditions resumed. After the data acquisition flight,
data from GPS base stations were checked against in-flight GPS data for concurrence.
Once data quality assessments were completed, all data (image and ancillary) were
transferred to a centralized location for pre-processing and quality control analysis.

After acquisition, the data were processed and analyzed, and the draft
data was uploaded to the RVCOG interactive mapping site (IMS). Final data delivery
and reporting concluded in August 2007.

The NOAA Coastal Services Center (CSC) received the files in las format.
The files contained lidar elevation and intensity measurements. The data were in the
Lambert Conformal Conic projection and NAVD88 Geoid 03 vertical datum. CSC performed
the following processing for data storage and Digital Coast provisioning purposes:
1. The data were converted from Lambert Conformal Conic coordinates to geographic
coordinates. 2. The data were converted from NAVD88 (orthometric) heights in feet
to GRS80 (ellipsoid) heights in meters using Geoid 03. 3. The data were filtered to
remove outliers. 4. The LAS data were sorted by latitude and the headers were updated.

The NOAA National Geophysical Data Center (NGDC) received lidar data
files via ftp transfer from the NOAA Coastal Services Center. The data are
currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/.
The data can be used to re-populate the system. The data are archived in LAS
or LAZ format. The LAS format is an industry standard for LiDAR data developed by
the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless
compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The
data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data
are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for
the ability to apply the most up to date geoid model when transforming to orthometric
heights.
