The first step in a measurement campaign (whether as survey, monitoring or surveillance) is usually a desk study to determine what data and information exists already. This should allow, amongst other things, an overview to be made of the regional and local coastal processes and sediment budgets, as well as local habitat changes, and provides a baseline for the local situation against which future change can be compared. Sources of existing information include literature, historic maps and charts, geological maps, aerial photographs and satellite imagery.

The sections that follow provide an indication of appropriate methodologies/available techniques for determining change at different geographical scales.
