Archaeological data management and spatial analysis tools in the study of necropolises: case studies from Bologna and Spina (6th-3rd cent. BC)

This contribution deals with the use of relational databases (RDB) and GIS for the spatial analysis of Iron Age funerary contexts in the Italian peninsula through two projects by the Chair of Etruscology at the University of Bologna. The two selected case studies of Bologna’s western necropolis and Spina’s Valle Trebba necropolis represent distinct phases of research and discuss the challenges in updating historic systems and creating dialogue between systems adopted at different times. The Bologna case provides the opportunity to discuss the quality of data from old excavations in reconstructing funerary landscapes using GIS. The case of Valle Trebba exemplifies the difficulties in planning and managing information on 1.215 tombs and over twelve thousand objects through an articulated relational archiving system. The iconography of Attic pottery allows us to understand the management of qualitative data. As far as spatial analysis in a GIS environment is concerned, we reassessed the solutions adopted for the Valle Trebba project, which are currently unsatisfactory, as they do not meet the principles of accessibility of such tools, nor Open Data Standards.
