Seymour, A., Dale, J., Hammill, M., Halpin, P and Johnston, D.2017Scientific Reports7: 45127 These RGB mosaics and thermal indices of Atlantic grey seal colonies at Hay and Saddle Island, Nova Scotia, were collected by small unmanned aircraft systems (UAS). The mosaics and thermal indices were assessed by human analysts, who counted the seals in the mosaic and classified individuals as 'young of the year' or 'adult'. Concurrently, an automated detection and classification model was applied to the datasets and compared to human counts.These datasets were used to assess Atlantic grey seal populations and to compare and test wildlife survey methods.The downloadable shapefile includes TIFF images of RGB mosaics and thermal indices. The size of the zipped file is 1GB and may take a long time to download. Within the dowloaded file, the 'Analysis Materials' folders contain point shapefiles of the seals counted and classified by human analysts. In addition, the folders contain the landscape masks that were applied to the thermal indices before running the automated detection models.2015013020150202ground conditionCompleteNone plannedNorth Atlantic Ocean-63.252503-59.68300246.02468245.813784 NoneMarine Animal SurveyMarine BiologyMarine mammalsComputer VisionUnmanned Aerial VehicalsUAVUnmanned Aircraft SystemsUASNoneNorth Atlantic Ocean Open public unless otherwise noted.
