Image, shapefile and digital elevation model (DEM) files collected by aerial drones on South Shetland Islands from 20250105 to 20250105 (NCEI Accession 0308393)

The data in this dataset include the polygons used for flight planning, the resulting orthomosaic image tiles, the digital elevation model (DEM), and shapefiles identifying elevation contours and the location of the nesting aggregations of chinstrap (Pygoscelis antarcticus) and gentoo penguins (P. papua) from the aerial survey at False Round Point.

The four file types are described below.

1. FRPT_Flight_polygons: This zipped folder contains the .kml files with the polygons used to plan the aerial survey at False Round Point. The mission was flown by two UAS simultaneously over an eastern (FalseRoundPoint_East.kml) and a western (FalseRoundPoint_West.kml) portion of the peninsula.

2. FRPT_Orthomosaic_tiles: This zipped folder contains contains 61 geoTiff (.tif) tiles (10000x10000 pixels) that constitute the full orthomosaic of False Round Point.

3. FRPT_DEM: The digital elevation model (.tif raster file) that corresponds to the orthomoasic of False Round Point.

4. FRPT_Shapfiles: This zipped folder contains shapefiles identifying elevation contours of the DEM (FRPT_contours[.shx, .shp, .prj, .qmd, .dbf, .cpg]) and locations of the nesting aggregations of chinstrap (FRPT_chinstrap[.shx, .shp, .prj, .qmd, .dbf, .cpg]) and gentoo penguins (FRPT_gentoo[.shx, .shp, .prj, .qmd, .dbf, .cpg])
