Résumé
As part of the ArchaeDyn project, a workgroup was formed to coordinate the development, implementation and application of methods and tools for spatial analysis. The workgroup's activities were directed at various problems. The first was to construct a grid common to all the workgroups and to homogenize the study areas used by the different workgroups in their databases. The 'confidence maps' method was suggested for assessing the quality and quantity of information inventoried in the databases. Confidence maps are produced from representation and reliability maps by simple map algebra and they can be considered as 'masks' for interpreting spatial analysis results. Finally, the research team tested, developed and adapted various statistical and geostatistical methods for defining the spatial indicators of stability over time (sustainability / permanent rhythms, changes, mobility / trajectories). This Chapter presents several exploratory analyses made within this framework.
