Circumpolar Arctic Man-made Impervious Surface Area (CAMI) Datasets

The CAMI product is generally organized and named as country-specfic rar files in Esri Grid format, with suffixes CA, US, and NE representing Canada, United States of America, and Nordic countries/regions including Norway, Greenland, and Iceland. Due to the large file size, we further divided CAMI within Russia into three parts: RU1, RU2, and RU3. The CAMI-2020 product is an updated version of CAMI that maps Pan-Arctic man-made impervious surfaces at a 10m spatial resolution circa 2020.

The product is provided in TIFF format, including six files representing six countries/regions (United States of America, Canada, Greenland, Iceland, Norway and Russia respectively) in the Arctic. Each file was named as "CAMI2020_" plus the countries/region name. The DN value of 8 represents imperviousness, while others are natural land covers.
