Abstract
Archaeological documentation is a fundamental step for research and conservation planning phases. Nowadays traditional recording is always supported by geomatics technologies which offer important support to the growth of archaeological study. The integration of sensors and methodologies seems to give the best results, in terms of time, costs and accuracy of products. In particular, the combination of Terrestrial Laser Scanner (TLS) and Unmanned Aerial Vehicle (UAV) can help the documentation of complex sites and the production of 3D and 2D products for different purposes. The paper focuses on the integration of TLS and UAV methodologies to record the thermal baths of the Roman Domus in the archaeological Park of Lylibaeum (Marsala, Italy). The combination of range and image data are useful to achieve a complete 3D model and a high-resolution orthophoto of the site, in order to provide accurate and complete documentation for archaeological research and conservative project.
Highlights
The integration of geomatics technologies satisfies expectations in many complex onsite surveys for archaeological documentation, with the challenge to choose, case-by-case, the most appropriate methodologies, depending on issues and features of the area

Summary
The integration of geomatics technologies satisfies expectations in many complex onsite surveys for archaeological documentation, with the challenge to choose, case-by-case, the most appropriate methodologies, depending on issues and features of the area. In the field of archaeological surveying, the combination of Terrestrial Laser Scanner (TLS) and Unmanned Aerial Vehicle (UAV) can help to optimize the documentation and to achieve accurate and realistic products [1]. TLS can be used to produce 3D point clouds with dense geometry information, UAV allows to acquire images for a photogrammetric survey of wide or inaccessible areas and provides information to derive geometry and texture for 3D modeling [2, 3]. Multi-sensor approach allows to fulfil all the surveying and archaeological needs and to highlight the intrinsic potentialities of each 3D modeling techniques [4]. The integration of different modelling techniques seems to be the ideal solution for a fast and low-cost survey [5].
