ARCHAEOLOGICAL GIS IN THE HNM 249 possibility of discovering new, so far hidden relations. Thus for a special archaeological GIS it seems most important to include versatile analytical facilities. Considering special features of ASIS, the set of analytical facilities cannot he limited to a permanent tool list. The wide choice of basic tools will be possible to increase by new tools as well as combination of the existing ones for a more efficient way of discovering hidden patterns and causal relations. The analytical facilities planned and performed in the first phase already facilitate such versatile analyses. The joint application of the given query conditions offer a wide range of analysis for the user. Spatial components in ASIS can he some environmental feature, its environment or a plane feature (point, line, circle, polygon) and its environment defined by the user. Thus the user has the possibility to study the environs of a site or sites, even finds, within a given area, along appointed roads or watercourses, within a given radius. The number of variations is increased by the extension of the concept of environment as included, outside, at the border of the study area and its combinations. The other great field of applications is concerned with an actual problem of spatial information systems, i.e., generating a 'patch', an area from occurrence points, which are an archaeological sect ion of points sharing the same feature. By provenance studies, there is a possibility to show on maps settlement structure of different periods or analyse similarity of contemporary settlements. In case of computer systems, it is a basic need to think about future development already in the phase of planning. Thus, apart from problems encountered in course of development, there is a great emphasis on questions concerning further development of ASIS. Such problems are feeding large amount of data into the system, importing ready-made or continuously developed digital archaeological topographical systems and databases 1 2 and their integration to the system as well as adding small scale digital maps to the system. The most important direction of our efforts is to create an online central archaeological GIS which is a complete archaeological and spatial database and which is available for every specialist through the network. 1 2 E. G., the database ADAM which is also made by the support of OTKA.
