The current DEM of Ammaia is composed in function of the geophysical surveys of 2008 and 2009. It comprises the area southeast of the bath complex, the bath complex itself, the forum and a large area north and northwest of the forum. For the areas that have not yet been covered with geophysical survey, the DEM has been complemented with data from the topographic map. Future geomatic work on the city site, as well as the planned LIDAR scanning of the area, must further refine these data.
