This hard drive contains data deliverables for NOAA's 2021 Airborne Hyperspectral Wild Rice Delineation project within the Lake Michigan-Huron Basin.
This data was created by the team of Galileo Group Inc. and Tetra Tech Inc. and its use is restricted to NOAA authorized purposes only.  

The structure of this data delivery is broken into airborne and ground/boat "field data".  The airborne data is subdivided into each of the twelve Areas of Interest (AOI).
For example, the Christiana Creek directory contains the following files and sub-directories:

Full_Band Mosaic:  This directory contains the following three files. 1.Christiana_Creek_Full_Band_Mosaic.dat (this is the full 178 band orthorectified reflectance mosaics covering the entire AOI in ENVI .data format).  2. Christiana_Creek_Full_Band_Mosaic.hdr (the technical header or metadata file for the .raw file).  3. Christiana_Creek_Full_Band_Mosaic.xml (the formal metadata file for the mosaic)
RAW_Data> this is the unprocessed airborne hyperspectral data and includes files with the following extensions.  .raw (unprocessed airborne hyperspectral imagery) .hdr (the technical header or metadata file for the .raw file) .nav (unprocessed GPS/INS navigation data)
Tiles> this directory contains the tiled hyperspectral imagery and is subdivided into three subdirectories.  Full_Band is the full 178 band orthorectified reflectance mosaic tiled out in ENVI .dat format.  RGB contains 3-band true color (RGB) subsets of the orthorectified reflectance mosaic tiled out in .tif and .png formats.  CIR contains 3-band color infrared (CIR) subsets of the orthorectified reflectance mosaic tiled out in .tif format.  All tiles are paired with corresponding .xml metadata files.
Vector_Geodatabase> this directory contains an ESRI file geodatabase that includes vector files for the AOI specific tiling scheme, the corresponding point centroids for the tiling scheme, and Region of Coverage (ROC) polygons that delineate the coverage for each flight line used in the final AOI mosaics.  All vectors are paired with corresponding .xml metadata files within the geodatabase.

The Field_Data directory contains the following subdirectories:
Geo-Tagged_Photos> this directory contains all of the geo-tagged digital photos in .jpg format collected during field operations.  A sub-directory called Spec_Locations_Photos contains a subset of only the spectrometer locations used for atmospheric correction and field validation in .jpg format.
Points> this directory contains vector point data collected during field operations in .GPX data along with corresponding .xml metadata.  Separate .gpx files for two different field devices have been included, 1. Trimble, this data was collected with a Trimble Pro XRT DGPS paired with a handheld Trimble GeoXM.  2. ARMADA, this data was collected using a Galileo created app on an iPhone 6 paired with a Bluetooth GPS receiver with sub-meter accuracy.  
Spectrometer_Data> this directory contains all field spectrometer data collected during field ops in individual .asd binary files along with an ASCII file in .txt format file containing all spectrometer readings for Wild Rice.  The sub-directory Atmospheric_Correction contains all field spectrometer data collected for atmospheric correction and validation during field ops in individual .asd binary files along with an ASCII file in .txt format file.


Analysis vector geodatabases have been added for all sites.  Each site directory has an Analysis_Vectors sub-directory which contains the vectors for all target classes delineated for that AOI.  
Each site also has there spectral endmembers in .txt format in its base directory.  
A site by site spreadsheet (NIGHTHAWK_2021_Class_Acreages.xlsx) breakout of the acreage for each class has also been added along with the final comprehensive project report in .pdf format.
