1. NGEEArctic_UAS_*_*_*_RGB.tif
-- Georeferenced Osprey RGB product, using ground control targets. The spatial resolution was rounded to the nearest interger centimeter
   Pixel resolution: 0.01 meters
   Spatial reference: WGS 84 / UTM zone 3N (EPSG:32603)

2.  NGEEArctic_UAS_*_*_*_RGB.json
--  Spatial extent of all of the L2 image products. 
    Spatial reference: Decimal Degrees, WGS84 (EPSG:4326)

3.  NGEEArctic_UAS_*_*_*_RGB.png
--  gdal generated RGB image quicklook

4. NGEEArctic_UAS_*_*_*_TIR.tif
-- Georeferenced Osprey thermal infrared product, by matching with the georeferenced RGB product. The temperature in this product was 
   scaled to interger using a scale factor of 10. The spatial resolution was downscaled to be consistent with the RGB product.
   Pixel resolution: 0.01 meters
   Spatial reference: WGS 84 / UTM zone 3N (EPSG:32603)

5. NGEEArctic_UAS_*_*_*_TIR.png
-- TIR image quicklook

6. NGEEArctic_UAS_*_*_*_DEM.tif
-- Digital elevation model (DEM) derived from PhotoScan DSM product.

7.  NGEEArctic_UAS_*_*_*_DEM.png
--  gdal generated DEM image quicklook

8. NGEEArctic_UAS_*_*_*_CHM.tif
-- The canopy height model (CHM) derived from PhotoScan DSM product. A digital elevation model (DEM) was first generated from the DSM, using the 
   method proposed in Yang et al., (2020). The CHM was calculated as the height difference between the DSM and DEM
   Pixel resolution: 0.01 meters
   Spatial reference: WGS 84 / UTM zone 3N (EPSG:32603)

9. NGEEArctic_UAS_*_*_*_CHM.png
-- gdal generated CHM image quicklook
