Field Activity 2022-030-FA

Identifier 2022-030-FA
Alternate names Assateague Island Phragmites Mapping
Purpose The purpose of the flights is to collect aerial imagery to use in vegetation classification models and elevation surface models in selected locations in the Assateague Island National Seashore.
Location Ocean City, Assateague Island National Seashore, Park Headquarters
Summary Recon mission was successful. The Altum-PT and Ricoh were deployed from the DJI M600 Matrice at 5 sites, collecting imagery and data. Vegetation surveys were also completed on foot at 4 of 5 sites with an RTK, spectrometer, visual identification and phone cameras. Wild horses were spotted.
Info derived Multispectral imagery (Micasense RGB, NIR, RedEdge) and RGB images (Ricoh)x to generate structure-from-motion Point clouds, DEMs, and orthos using collected GCPs (plus additional rtk check points) and georeferenced images.
Comments Field Activity will have two parts - a two-day recon mission will be done by Cramer and Brosnahan in September to establish benchmarks (if necessary) and figure out logistics before the entire group does field work at the site in October from the 9-15th. Funding is split over the fiscal year.
