| 2007 Bureau of Land Management (BLM) Lidar: Panther Creek Watershed, Yamhill County |
| The dataset represents LiDAR elevations acquired during a leaf-off and a leaf-on vegetative
condition for the Upper Panther Creek Watershed in the Yamhill County study area in
Oregon. The date of collection for the leaf off data is 20071208. The date of collection
for the leaf on data is 20070903. The area of interest covers ~5577 acres (~8.71 sq
miles). The LiDAR survey utilized a Leica ALS50 Phase II laser mounted in a Cessna
Caravan 208B set to acquire > or = 105,000 pulses per second (i.e. 105 kHz pulse rate).
The scan angle was +/- 14 degrees from nadir. These settings are designed to yield
an average native density (number of pulses emitted by the laser system) of > or =
8 points per square meter over terrestrial surfaces. LiDAR intensity values were also
collected. 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.
Watershed Sciences, Inc. collected the LiDAR and created this data set for the Bureau
of Land Management.
