footprint

The footprint module is used to create the 2D footprint of a plume_shell.  It creates a surface at the specified Z Position with an x-y extent that matches the 3D input.  The footprint output does not contain data, but data can be mapped onto it with external kriging.  

NOTE: Do not use adaptive gridding when creating the 3D grid to be footprinted and mapping the maximum values with krig_2d (as in the example shown below).  Footprint will produce the correct area, but krig_2d will map anomalous results when used with 3d estimation's adaptive gridding.

Module Input Ports

• Input Field [Field] Accepts a data field.

Module Output Ports

• Output Field [Field] Outputs the subsetted field.
• Output Object [Renderable]: Outputs to the viewer.

NOTE: Creating a 2D footprint with the maximum data within the plume volume mapped to each x-y location requires the external data and external gridding options in krig_2d.  A typical network and output is shown below.
