The data includes topographic data in an LAS format file. The data was collected 31 July - 1 August 2008 on the Kenai Peninsula of Alaska. It has been processed to bare earth using only an automated routine - additional manual editing is required for localized use. The data covers portions of the Outer and Inner Kachemak Bay coastline from Point Anchor to Homer and along the coast into the head of the bay. The data falls in the Kachemak Bay National Estuarine Research Reserve and includes the Fox River Flats Critical Habitat Areas. This lidar was acquired by the NOAA Remote Sensing Division to support NOAA's IOCM initiative. It is not intended for mapping, charting or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar. Data include all lidar returns (first, second, third, and last) and have been classified to bare earth by the National Geodetic Survey (NGS) using only automated processes. "Outliers" or "false returns" (e.g., returns from birds, atmospheric particles, and/or system noise) may be present in the data. 20080731 20080801 Ground condition Complete None planned -151.897942 -150.847142 59.853050 59.596050 ISO 19115 Topic Category Elevation None Bathymetry/Topography LIDAR Elevation None United States Alaska Kenai Peninsula Cook Inlet Kachemak Bay Kachemak Bay National Estuarine Research Reserve (NERR) Homer Homer Spit Point Anchor Fox River Flats None 20080731 20080801 None 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.

OS Independent Not applicable Not applicable The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 2.0m. 2.0 2 Sigma The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.30m. 0.30 2 Sigma Data were processed to an initial LAS format using the ALTM DASHMAP software. The Applanix POSPac software was utilized for GPS and inertial processing, and Terrasolid software for data visualization, 3D editing and export to final LAS file. Data were processed in NAD83 horizontal and vertical datum. 20081006 The NOAA Coastal Services Center (CSC) received files in LAS format. The files contained LiDAR intensity and elevation measurements. CSC performed the following processing on the data to make it available within Digital Coast: 1. The data were converted from UTM coordinates to geographic coordinates. 2. The LAS header fields were sorted by latitude and updated. 3. The data was filtered to eliminate outliers. 20081207 Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC) CEM Project Scientist Mailing and physical address
