High density remote survey technologies (TLS, ALS, Photogrammetry, etc.) have become widespread practices. In recent years, we have seen a tenfold increase in volume of digital data acquired. Beyond this sheer amount of data, multimodal three-dimensional data exploitation has become another common challenge for specialists, whether it be computer scientists or ordinary users.
The Aspectus project aims to ease the access to complex three-dimensional data and to promote collaborative work and remote expert assessment. Thus, we can get past the problem of distance and availability of the “object of expertise”, ranging from cultural heritage sites to artefacts. By extension, it enables us to circumvent the ever-present problem of destruction, be it as a result of the excavation itself or as a consequence of natural events or human activities.
From a technical point of view, Aspectus takes advantage of available open source solutions (A-Frame, Potree, 3DHop, Humhub, etc.) to produce a flexible web-based team collaboration tool. It works with commonly used browsers which means no additional installation is required.
With such dynamic and flexible solutions, we can make available innovative visualization and interaction interfaces such as: desktop VR headsets or smartphone VR headsets and Vive/Touch or LeapMotion controllers. We acknowledge the fact that those technologies have added value but remain of circumstantial use and may not be widely available at the moment.
Our top priority is to enhance available collaborative tools by allowing users to easily annotate and share hypothesis and interpretive materials. By extension, we also aim to give the ability to record and share digital assessment sessions (viewpoint and gesture).

Relevance conference / Relevance session:
Our tool relies on innovative open source solutions to ease the process of accessing and assessing complex multimodal 3D data related to cultural heritage.

The innovation lies in our ability to blend high quality multimodal and multiscalar 3D data and access it through a web-based collaboration tool.
