Error Modelling

There are three methods for associating an error model (or surface), with a DEM survey in GCD:

  1. Add an Existing Error Surface
  2. Calculate an Error Surface
    • Specify a Spatially Uniform Error Surface
    • Load an Associated Surface as an Error Surface
    • Run a spatially-variable FIS Error Model
  3. Calculate Error Surface with a Mask
