Recent studies carried out on Gallo-Roman site of Grand (France) illustrate the interest of using integrated methods in characterization of past occupation. Combination of excavations and surface surveying based on non-invasive techniques (such as geophysical surveys, LiDAR, aerial photography) allows a better identification of features. The cross-analysis of all data in GIS improves the global comprehension of the city framework and of its hydrogeological environment. Two case studies are presented: first we compare geophysical maps to speological observations for the detection of drainage galleries; then we show results of excavation and geophysical data in southern district of the agglomeration.
