Definitions: Stitched vs Tiled Images

Note: The following are LOCAL definitions provided to clarify for Imaging Services staff and customers what we mean when we refer to stitched and titled images.

STITCHED IMAGE

To create an image of a subject, the subject is photographed in sections. The stitched image is created by overlaying the component images so that common image-elements are aligned and blended to create a single, seamless image of the subject. [example]

TILED IMAGE

A tiled image is created from component images that are aligned but not overlaid. Like a stitched image, a tiled image might be an arrangement of component images that together represent a single piece photographed in sections. Unlike a stitched image, the component images are not overlaid, and common elements are not aligned to create a seamless representation of the subject. A tiled image can also be used to create a single view of multiple discrete images that benefits from a representation where the arrangement of images produces a composite view that has special value.
