Photo Mosaics In Shallow Water Environments:
Challenges And Results

Abstract
Photo mosaics of underwater sites are useful tools for interpreting sites and
increasing the level of detail for areas too large for conventional photography.
While this tool has been used for years at deep-water sites using camera
platforms, such traditional devices are difficult to use in areas that are too
shallow or too rough to maintain a consistent distance to the site. In addition,
some sites, notably large shipwrecks, cannot be photographed at a well-maintained
distance given the time constraints of many projects. Finding
alternative methods to collect data and create photo mosaics is necessary.

1 Introduction
Data collection and documentation of shipwreck sites involves a variety of
methods and techniques depending on the location of the site, the size of the site,
the time constraints of the survey and the technology available to the researcher.
Data collection using various photographic techniques is a common component
to most surveys. This typically involves the conventional gathering of visual
images using still images or streaming video with an underwater camera or a
camera equipped with underwater housing, all of which are accessible to most
researchers.
In addition to the traditional images collected using this method, researchers
are increasingly turning to the manipulation of these images into a larger image
made up of a collection of stills and covering the all or part of a site or
shipwreck. Known as photo mosaics, these can be created using a number of
