A measure of the closest distance between two unique identifiable features or the size of the smallest feature that can be mapped or sampled [1,2]. It is often divided into three subcategories:
- Observational resolution: the size of the smallest feature that can be mapped or sampled (also known as Ground Resolution Unit (GRU) or Minimum Discernable Unit (MDU)).
- Representational resolution: the smallest object that can be shown in a map/data layer (also known as the Minimum Mapping Unit (MMU))
- Management resolution: the smallest unit of relevance to a given management consideration (e.g. a biotopeor a microcommunity).
