Integrating laser scanning, multispectral imagery and gis in C & R documentation practices: a first approach using two xvith century wood paintings from convento de cristo in tomar

This article addresses the application of geomatic technologies in the field of painting conservation and restoration (C & R). It results from collaboration between geomatic professionals and conservators-restorers and intends to gradually integrate techniques like photogrammetry, laser scanning, multi-spectral analysis or geographic information systems in the daily work of C & R. In this phase we have focused our efforts in the specific field of retable wooden painting using as case-study paintings from the XVIth century belonging to the Convent of Christ in Tomar, Portugal, that are part of a large dimension retable composed originally by twelve pieces in the deambulatory chapel of the convent church. Until now, at least in Portugal, painting C & R does not use any of the documentation standard procedures already applied in other cultural heritage fields like archaeology or architecture. The conceptual plans for future research along with the results from the laser scanning and photogrammetry campaigns are presented. Preliminary achievements with a multi-spectral analysis system will also be stated as part of the work in progress.
