I tried the site for ICE unfortuantely it is a Windows platform, I am a Mac user. This sounds good, combine smaller number together and then add the combined together into one Pano. The reason of the 36 images was that it is a university campus, colleges, and everything else that is needed to have a university city. The location was a construction site, I read somewhere that it is good for Panos to be shot in portrait, so I did, which took with the overlap 36 snaps to cover the whole ground from one end to the other, moreover I think this was increased due to the fact I overlaped each picture almost 50%. Whereas the other Pano I made from the same site it took around 12 pictures to cover the whole site in landscape, and it worked just fine.
