## 2 Background
It brings together all the information available to the Soprintendenza Speciale Archeologia Belle Arti e Paesaggio di Roma, and is accessible online by the general public [40; 41] (Figure 4). Figure 4: Italy STAR project: graphic illustration of “Domus Aurea” on the map associated with the database. Figure 3: Italy C.A.R.T. project: graphic illustration of how to present information on the map through polygons of different colors using Odysseus software. In 2021, Greece made available to the public The Archaeological Cadastre Portal [42], which is an integrated information system for evidence storage, documentation, and management of national heritage (Figure 5). There are different approaches in this area in Spain, following the transfer of competences in the field of conservation of the archaeological heritage to the regions. In this context, the Information System on the Archaeological Heritage of Andalusia (SIPAA), called ARQUEOS, was initiated in 1989. This system is accessible by the public [43,44] and is required as a model. Efforts to provide evidence of archaeological heritage are also made in the European countries of the former communist bloc, although results are still modest (see the cases of Hungary, Romania, etc.) [45,46]. In Romania, the Ministry of Culture initiated two databases that aimed to record the archaeological heritage: the National Archaeological Repertory (R.A.N. ; 2004) [47] (Figure 6); and the National Program for the Implementation of a Geographic Information System (GIS) for the protection of the immovable cultural heritage (archeology and historical monuments) (eGISPat; 2006-2013) [48, 49, 50]. The administration mode of the R.A.N., centralized by the Ministry of Culture through the National Institute of Heritage, and without the direct involvement of the Ministry of Culture territorial branch offices, determined that the number of registered sites should be reduced, some without a geospatial location, with a series of errors and inconsistencies. In addition, the poor management of the implementation of the eGISPat program at the national level meant that the program did not achieve the expected outcome; the program was implemented only at the level of 8 of the 41 territorial structures, and the general situation was rather dysfunctional [14]. Figure 5: Greece The Archaeological Cadastre Portal: screenshot showing different types of monuments and archaeological sites. As a result, the research project outcome, namely the ArchTerr web application, is a necessity in the context of the new orientation for the protection of archaeological heritage. The project through which the ArchTerr application was built was financed from public funds. The aim was to build a software application to help protect the archaeological heritage in Romania (Figure 7) which, by its geographic positioning, was at the confluence of several civilizations during history. Figure 6: Romania, the R.A.N. website: screenshot with archaeological sites represented (“burial tumulus” type). Figure 7: Europe map highlighting the territory (Romania) where the ArchTerr project pilot phase was implemented. In the process of testing and validating this application, three counties were initially involved, through the territorial offices of the Ministry of Culture. Later, four more counties asked to be added to the project (Figure 8).
