What do you mean by "standalone mode"? The models (including the RPC model) depend on access to elevation data -- or at least an ellipsoid. That is built into the model so I don't understand what you mean by "standalone".

i have created an object of ossimRPCmodel
n i am using it as a standalone mode
using function setAttriibutes() function , i am able to initialize 90 values in RPC file i.e offset and scale value of line and sample and 80 RPC coefficients.
now i would like to convert pixel coordinate to lat/long for that i am using localtoworld() but its not converting.
what can be intermediate steps or function should i use to have conversion after setAttriibutes() before localtoworld() ?
