Primitive Weighting

The toolbox includes a tool for populating the primitive weighting coefficient for each node based on the node spacing and the node depth. Specify a threshold for node spacing (Critical average node spacing) and depth (Critical depth). The defaults for these are 1750 m and 10 m respectively. Also specify a values for tau for three conditions including default (0.03), deep (0.005) and shallow (0.02).

If the average distance between a node and its neighbors is less than the critical value then tau0 for that node is set at the tau default. If the average distance between a node and its neighbors is greater than or equal to a critical spacing then tau0 for that node is assigned based on the depth using the deep or shallow value specified.

The Primitive Weighting tool dialog contains the following options:

  • Target grid – This is a required input parameter. Specify which grid/mesh the primitive weighting dataset will be created for.
  • Critical average node spacing – Set the threshold for node spacing.
  • Critical depth – Set the threshold for the depth.
  • Tau default – Set the default for tau for when the average distance between a node and its neighbors is less than the critical value.
  • Tau deep – Set the deep value for when the average distance between a node and its neighbors is greater than or equal to a critical spacing.
  • Tau shallow – Set the shallow value for when the average distance between a node and its neighbors is greater than or equal to a critical spacing
  • Primitive weighting dataset – Enter the name for the new primitive weighting dataset.
