Creates a new file with math band(s) based on an input source file with the option to retain source file bands in the new file. |
Example 1 Create only Math Bands
This creates a new file based off an input source file adding math band(s) to it (the bands and masks of the source file are not transferred to the output file).

Here is what example 1 would look like if you use the GUI, in which case there are no variables. The following graph will load into the GUI via the GraphBuilder tool (note: you need to edit the ifile and ofile paths).
Also note that 3 fields of the BandMaths tool are not available within the GUI but are available at the command line: validExpression, spectralWavelength, and spectralBandwidth.

Example 2 Create Math Band(s) plus chlor_a and Kd_490
This creates a new file based off an input source file adding to it Chlor_a, Kd_490 and math band(s) (the bands and masks of the source file are not transferred to the output file).

Example 3 Create Math Band and Retain chlor_a and Kd_490 Bands (Variables Option)
This creates a copy of a file adding math band(s), chlor_a and Kd_490 bands to it.
This is exactly the same as example 2 except it illustrates the use of the variable options.
Note: variables only apply to parameter "expression" and not to parameter "validExpression".

Example 4 Remove the "_count" Bands from a Mosaic File (OC Level2)
For each band in a Mosaic file there is a corresponding "count" band used in its validPixelExpression (for instance the chlor_a band sets it's validPixelExpression based on the chlor_a_count band: expr= chlor_a_count > 0). In this example we take a Mosaic file and by using the BandMaths operator to apply the validPixelExpression, we create a new file which does not contain these "count" bands.
This example is doing the full set of 20 bands in the OC suite (Note: this example has been prepared during the SeaDAS 7.5 release, so any product changes in the future for the OC suite are not accounted for here).
The source file A2017023193500_MosaicEx05.dim used here was produced by Mosaic Example 5
