I recently did a job for a client where they needed some very high resolution panoramic photos of the Sundial Bridge in Redding.
I spent a very beautiful day shooting around the bridge, making high resolution panoramic images, consisting of three to six stitched 21 megapixel images. The resulting images are 9000 to 12000 pixels wide.
You can see the full set of panoramic photos from that shoot here, or look at the samples, below (best viewed larger).
