Data from Migratory Bird Aerial Surveys and Habitat, Nest Success, and Genetic Samples from Spectacled Eiders (Somateria fischeri) on the Indigirka River Delta, Russia Data from Migratory Bird Aerial Surveys and Habitat, Nest Success, and Genetic Samples from Spectacled Eiders (Somateria fischeri) on the Indigirka River Delta, Russia
This data release contains five spreadsheets of information from aerial surveys of the Indigirka River Delta, Russia, in June of 1993 and 1994, data on habitats where nests of Spectacled Eiders (Somateria fischeri) and other species of waterfowl were observed from 1993 to 1995, and genotypic data from feathers collected from eider nests to determine inter-annual rates of return by...
Synthetic Elevation Checkpoints, North Carolina Synthetic Elevation Checkpoints, North Carolina
These geospatial datasets describe positions, elevations, and uncertainties for synthetic elevation checkpoints generated across the developed coastline of North Carolina. Two datasets are provided as point shapefiles and American Standard Code for Information Interchange (ASCII) tables, and each contains synthetic checkpoints generated using a time series (1996-2018) of digital...
Low-altitude aerial imagery and photogrammetry products from unmanned aerial systems (UAS) flight after the 2018 flood over historic Ellicott City, Maryland Low-altitude aerial imagery and photogrammetry products from unmanned aerial systems (UAS) flight after the 2018 flood over historic Ellicott City, Maryland
Digital imagery was obtained by Elevated Media Concepts LLC from small unmanned aerial systems (UAS), over Historic Ellicott City on June 18, 2018 after major flooding events. The imagery was collected to document and monitor effects of flooding, including property damage and erosion in Ellicott City, Maryland. A DJI Inspire 2 quadcopter with camera model FC6520 and a DJI Mavic Pro...
