| This paper describes a method that refers to the integration of analogic data of an Atlantic salt marsh atlas into a GIS. So the steps of the method are developed after a description of the original data sources in the form of analogic thematic cartography and associated text. They include digitalization, geometric corrections, topology and attributes definition, hotlinks setting up between graphics, texts and images, information layers crossing and spatial analyses. Four main results are presented and discussed: (a) the atlas digital form presentation, (b) objects selection and theme surface computation in the case of salt exploitation, (c) salt marsh identification versus inland fresh water marshes, (d) intersection between digital atlas objects and... |
