Land Cover Overview
Land cover is a grid which assigns a code to each point in the data set based on occurs there. It differs from land use, but obviously the two are related. The code is normally a byte, and there are usually a few dozen categories. They are created from satellite imagery such as Landsat or Sentinel-2, and due to clouds and collection schedules the imagery is usally from about a year in time.
