Suppose I have to geo-rectify a image which spread on two UTM zone (like UTM Zone 44 & 45) and I also have to digitize it on a single shape file. The out put file also have to in UTM Projection System. What should I do? Any advice is welcome.

Tough call. If the image is mostly in one zone I'd keep the whole thing in that one. If it's (almost) split down the middle you can maybe suggest another projection to your client?

Yes really a tough problem. I can use another projection or I can split the vector and raster into two different zone. But when I am going to make a survey with GPS/DGPS or Total Station or RTK then which coordinate system I will use.
