Abstract
Change detection studies require that all spatial informa-tion
be registered to a common coordinate frame. A pre-vious
image-to-map rectification study was performed by
registering pixel locations to map positions in a local coor-dinate
frame for all images in the time series. However,
the precision of this study was unable to be quantified due
to the uncertainty of the map generalisation (Israel et al.
1996). A better technique is to register a single image to
the coordinate frame either by using conventional survey
techniques, such as GPS, or by having known camera posi-tion
and orientation parameters (internal and external
control). The geocoded image becomes the base map. The
other images are then registered to the image base map.
In this case study, we have used the North Basin of the
Dead Sea as our study area. We compared our results to
those found by multiple image-to-map registrations.
