Creating an operator

TerraAIDA project aims to build InterIMAGE operators using the TerraLib library following the GNU LGLP license model. More information at http://www.dpi.inpe.br/terraaida/.

This page will present an example of how to create your own InterIMAGE operator, using TerraLib.

After created, your operator must have two files, to be inserted into InterIMAGE:

• The binary, which will perform the implemented operation,
• The .op file descriptor, which describes the parameters, understandable by InterIMAGE GUI.

The structure of the files should follow this example in order to run properly.

#include <execTAArithmetic.hpp>
#include <OpSupportFunctions.hpp>
 
#include <iostream>
 
int main( int argc, char ** argv )
{
  // if executed with no parameters
  if( argc == 1 )
  {
    std::cout << std::endl << "TerraAIDA arithmetic operator - Version " + 
      OpSupportFunctions::getTAVersion() << std::endl;
    return EXIT_SUCCESS;
  }
 
  // if executed with parameters
  return TerraAIDA::execTAArithmetic( argc, argv );
}
