ABSTRACT Especially in archaeology, a mission of the surveyor is to acquire and to work on data generated by an experimentation field, i.e. to locate natural elements or human constructions, and to represent them (analogically or digitally). Surveying work has always been part of field archaeology, because the knowledge and expertise of the surveyor can be as useful for the prospecting stage as for the excavation. However surveying practices carried out in archaeology could change, and the surveyor could be proved helpful for the use of excavated data too. The purpose of this paper is to summarize how topographical techniques are used by the archaeologists, and to present the evolution and potential of computer developments, especially regarding data management. Historically, a number of cartographic tasks in archaeology was taking care of by the surveyor, e.g. cartography of excavation fields, absolute positioning of distinct sites, aerial prospecting, study of old maps and archive images, levelling, etc. Today, the archaeologist makes more and more the field surveys himself, however the role of the surveyor could change in the future. He will be able to help the archaeologist in his data exploitation work as well. The new expertises of the surveyor, e.g. Databases and Geographic Information System (GIS), allow him to handle different kinds of data efficiently. These knowledge should be interesting for the archaeologist, both in simplifying data management and in developing novel techniques for presenting the resources. Moreover, to have an overview of all data available could lead to innovative analyses, based for instance on interactive 3D models linked with databases or on modelling of historical evolutions. Then, the surveyor competences are extending and will permit him to offer the archaeologist new possibilities for the utilisation of all types of documents allowing to approach the Human Past. 1.

The second part concerns the new expertises of the surveyor and the potentialities that follow for This paper gives a technical overview of surveying practices in data management. Three aspects can be considered: the reasons archaeology, to show their evolution and the perspectives that for computerizing archaeology, the knowledge of surveyors for appear thanks to computer developments, particularly regarding the data management, and finally the benefits of data cultural heritage data management.

Field The article can be broken down into two parts: the common archaeology is the part where the expert carries out excavations, practice of surveying in archaeology and its evolution, and then gathers traces and collects evidences. Whereas office the potential of the computer for the management of cultural archaeology get together researchers who study in laboratory heritage data. The first part of this paper deals with surveying these evidences of the past, to draw conclusions permitting to work on an archaeological site. Two steps are coming out: reconstitute the men's life at a given epoch. It is then worth generalities on the link between archaeology and surveying, and nothing that to be able to draw valid deductions of this studies, examples of common surveying practices in archaeology with it is important not to isolate the found objects from their ________CIPA 2005 XX International Symposium, 26 September – 01 October, 2005, Torino, Italy________ context.

Moreover, it makes sense to perform Moreover, the archaeologist has considered for a long time each comparative studies of ancient maps, on the one hand, and excavation field as an isolated and independent site.
