Deepgis, I don't think tou could perform that in Agisoft. (sorry pasfans01, but I'm disagree with you)
Cartosat-1 is a pushbroom system, not a framed one. That means the camera scan the ground track line by line continuosly, as spatial vehicle move foward in orbit.
So, in order to achive results you need camara position for each scan line, more than 10.000 per scene, that means more than 20.000 cameras for agisoft (you need 2 scenes)
Besides agisoft search for tie points usin images patchs, and you only could get part of a single line as a patch.
Even if (with a miracle) you could make the software go, I don't think you could get any acceptable results, even with very low resolution
Use PCI, ENVI or Erdas. lot less painfull, lot better results and the most important: proved solution
