Bare Earth LiDAR point cloud data provided for this project is compliant with FEMA Guidelines and Specifications Procedure Memorandum 61.
LiDAR derived products for two areas of interest within the Cordova, Alaska area, consisting of 32 square miles, were developed to support coastal or riverine H&H analysis and floodplain boundary delineation.
The NOAA Office for Coastal Management (OCM) downloaded this data set from this AK DGGS site:
https://elevation.alaska.gov/
These files were processed to the NOAA Digital Coast Data Access Viewer (DAV) and AWS S3. The total number of files downloaded and processed was 17.
No metadata record was provided with the data. This record is populated with information from the FEMA Starr technical and QA reports downloaded from the Alaska Dept. of Geological and Geophysical Elevation Portal.
In addition to the lidar point data, the bare earth Digital Elevation Model (DEM) data at a 1 meter grid spacing, created from the lidar point data are also available from the NOAA Digital Coast. Links to these data are provided in the URL section of this metadata record.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
