The systematic analysis of landscape through photographs taken from the ground, as practised by the geographers of Besanon, rests on the development of banks of landscape images collected by sampling the area. This sampling differs according to the size and scale of analysis, the geographic structure of the area considered, and depends on whether a surface or a linear entity is to be sampled. These investigations allow both spatial and temporal study of the landscape.

Concurrently, current research into computational vision shows a need for software which allows one to collect various perceptual features and their characteristics as these appear to someone observing a natural scene. So, one seeks to study factors involved in the delineation of regions of perceptually significant images and, more generally, the interactions between elements that are juxtaposed, superposed, and function in an emergent dynamic.

Whatever the scale of the study, large collections of photos are gathered (hundreds to thousands): Their analysis and their restitution pose some problems that computer science and multimedia can resolve.

In passing from the rough corpus of photos to a bank of analysed and indexed images, we are constructing an integrated computational tool.

It has two potential uses:

We will present the architecture of the integrated tool of landscape analysis using a landscape study from an Arctic area (Svalbard, Kings Bay, 79oN), focusing particularly on three aspects:
