BEST BEFORE? ADVANCED GEOMATICS FOR PRESERVATION AND PRESERVATION OF ADVANCED GEOMATICS

Abstract. This discussion paper deals with the task of preserving past geometrical surveys and keeping them in use. The continuous advancement in technology caused a quick ageing of both survey techniques and their outcomes. This may result into a predetermined expiration date after which they risk losing their quality and usefulness (hence the title «Best Before»). Facing this risk, this paper focuses on the unceasing relevance of past surveys both as a legacy in the history of technique and as a fundamental source of information on heritage buildings, and thus a support to the preservation activity. The present paper offers an overview of the most recent attempts of preserving and keeping in use the paper surveys of the past.
