Summary
This representativity index is based on how many stations exist within a grid of 50 km by 50 km. This number is adjusted by landscape variability, and variability is defined by the number of unique elevation values within a 50 by 50 km window. A 50 km by 50 km window with only one elevation value (very flat), can be well represented by one station; however a complex landscape like the sierra might need more stations to be better represented. In this raster layer, the higher values represent more uncertainty; lower values represent less uncertainty.
