Classification of images taken by small mammal cameras on the Varanger peninsula. The dataset contains data on presence or absence of small mammal species (Birds, Voles, Lemmings, Shrews, Least weasels and Stoats). The images were classified automatically and in addition to the data files, there is a file describing the machine learning model and files with information about the quality of the automatic classifications for each year.

The dataset includes six different types of files and all data files are saved as ;-separated txt-files:

  • One data file per year and locality (locality_YEAR.txt)
  • One coordinate file with coordinates of all sites (_coordinates.txt)
  • One auxiliary file with information about which sites are included in the study design (_aux.txt)
  • One readme file with additional information (_readme.pdf)
  • One file with a description of the machine learnomg model used for automatic classfication (_small_mammal_classification_model_v2021_summary.pdf)
  • One file per year with information about the quality of the automatic classifications (_quality_check_YEAR.pdf)

Image metadata is available in the dataset 'V_rodents_cameratraps_image_metadata_lemming_blocks'. Manual classification of all images from 2015 to 2018 is available in the dataset 'V_rodents_cameratraps_manual_image_classification_lemming_blocks'. Information recorded during the annual camera check is available in the dataset 'V_rodents_cameratraps_annual_metadata_lemming_blocks'.

The data is not publicly available yet.
