The compute surface area module is used to calculate the area of the entire field input. The input data must be a two dimensional data field output from a 2D estimation, slice, or any subsetting module which outputs two-dimensional data (slice, plume with 2D input, or plume shell). The module can compute either the full 3D surface area or the projected 2D plan area. The results of the integration are updated each time the input changes.

Description
Z Scale
Double
The Z Scale is required to assure that computed area is conformal to scaled input data.
Area To Compute
Choice: 3D Surface Area, 2D Plan Area
Controls whether the 3D surface area of the input field or the projected 2D area is computed.

Double
The Integrated area of the input field. Read-only output value.
Area Units
String
The units of the input field squared. Read-only output value.
