2006-11-10: Binary Grid Proc. Service

From Datafedwiki

The binary operator service takes two grids as inputs, performs a calculation on them, and generates an output grid.

Inputs:

Grid a
Grid b
Selected Operation or user defined expression
Spatial bounding box in which operation should be executed
Spatial resolution of the output grid (x,y dim)

The grid inputs can include WCS GetCoverage request or an SOS GetObservation request that returns an embedded URL to a grid file. The resultant grid is accessible through a URL provided in the SOAP output. The grid format is in DataFed binary format. A conversion service can be used to translate it to other formats, such as netCDF, GeoTiff, and JPEG.

Available operations include add, subtract, multiple and divide. User defined expressions can also be defined, such as 2*a - b.
