[gdal-dev] gdaltransform utility not working in web service

[Dinesh Dass Subramanian]

Chaitanya,

The inputAoiPath contains the list of the input coordinates to be
transformed. The path to the tiff file contains the RPC file using which
the transformation is performed. The outputAoiPath file contains the
transformed coordinates. Thanks.
