Title: 2012 NOAA Fisheries Topographic Lidar: Bridge Creek, Oregon
Short Name: or2012_noaa_bridgecreek_m3676_metadata
Status: Completed
Publication Date: 2014-12-01
Abstract:

This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. In March 2012, WSI (Watershed Sciences, Inc.) was contracted by Woolpert, Inc. (Woolpert) to collect Light Detection and Ranging (LiDAR) data and digital imagery in the fall of 2012 for the Bridge Creek LiDAR site in Oregon. The LiDAR survey used a Leica ALS60 laser system, classified to ground and non-ground points, stored in LAS 1.2 format. WSI (Watershed Sciences, Inc.) was contracted by Woolpert, Inc. (Woolpert) to collect Light Detection and Ranging (LiDAR) data for the Bridge Creek LiDAR site in Oregon. The project area delivered is 9163 square acres. These files contain classified topographic lidar data as unclassified valid topographic data (1), and valid topographic data classified as ground (2). Classes 1 and 2 are defined in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards.

Purpose:

This task consists of the collection of LiDAR, and half meter color digital aerial imagery for the Bridge Creek area. Data were collected to aid Woolpert and NOAA Fisheries in assessing channel restoration along Bridge Creek.

Data Quality

Accuracy:

The LiDAR was collected and processed to support a 95% confidence level | Quantitative Value: RMSE less than or equal to 15cm | Quantitative Test Explanation: These data are not attributed

Horizontal Positional Accuracy:

Relative errors for the position must be less than 1.5 cm horizontal and 2.0 cm vertical in order to be accepted.; Quantitative Value: 1.0 meters, Test that produced the value: 100 cm, not tested

Vertical Positional Accuracy:

Absolute accuracy is described as the mean and standard deviation sigma of divergence of the ground surface model from ground survey point coordinates.; Quantitative Value: 0.019 meters, Test that produced the value: +/- 1.9 cm, RMSE

Completeness Report:

Topological and attribute accuracy was verified by visually examining the data in its final format

Conceptual Consistency:

Topologically clean

Process Steps

Process Step 1

CC ID: 624936
Description:

The LiDAR survey was accomplished with a Leica ALS60 system mounted in a Cessna Caravan. Table 6 summarizes the settings used to yield an average pulse density of greater than 8 pulses/m2 over the larger Bridge Creek LiDAR acquisition and of greater than16 pulses/m for the priority reach areas.

Process Date/Time: 2012-09-27 00:00:00

Process Step 2

CC ID: 624937
Description:

The NOAA Office for Coastal Management (OCM) received the topographic files in LAS format. The files contained lidar easting, northing, elevation, intensity, return number, etc. The data was received in UTM Zone 10, meters. The vertical coordinates were referenced to NAVD88 in meters using the Geoid03 model. OCM performed the following processing for data storage and Digital Coast provisioning purposes:

1. The data were converted to LAZ format. 2. The vertical coordinates were reprojected to ellipsoidal heights and horizontal coordinates were reprojected to geographic.
