Acquisition of accurate archaeological heritage data is fundamental for the prospective steps of architectural conservation process. As of today, digital data capturing technologies such as image-based and range-based systems are rapidly becoming prevalent and generating digital surface representations of the object(s) in the form of three-dimensional point clouds. Point clouds assist heritage experts to carry out heritage analysis in digital forms, in particular to conduct condition assessment based on orthophotos of archaeological assets. In this paper, we introduce an integrated strategy by using Terrestrial Laser Scanning (TLS) and photogrammetry for the scope of obtaining orthophotos as basis for analyzing geometric, texture and color information of archaeological remains. Such a combination allows overcoming insufficiencies especially in terms of color due to the high natural light exposure. To remedy such visual obstacles, this paper demonstrates results to generate maximum visual data coverage of an archaeological heritage asset for the conservation process.
