| Title: | High-resolution orthoimagery of the Altamaha River estuary in November 2017 and October 2018 | ||
| Abstract: | We acquired two high-resolution (0.15-m per pixel) color digital images of the salinity gradient of the Altamaha River estuary in November 2017 (1 month after Hurricane Irma) and October 2018. Flights ranged from the mouth of the estuary all the way up to the tidal fresh forest habitat. The 1:1200 scale orthoimagery is comprised of 4-bands (Red, Green, Blue, Near Infrarad (RGBNIR)) collected with a Ground Sample Distance (GSD) of 0.5 foot using a Leica ADS100 airborne digital sensor. Individual tiles were georectified using ground control points and merged into a domain-wide mosaic. | ||
