What is Aspectus?
A digital workspace to visualize and annotate multimodal and multiscalar 3D data, for archaeology and cultural heritage.
Mixing a professionnal social network interface with highly efficient web visualization tools.
reflections on complete workflow to manage archeaological digital data from field to archiving, dissemination and valorization

a museum (1996)
a research centre (1995)
Accumulation of digital data since 20 years

Technical insights, feeding the front end
.assessing and processing 3D spatial data
Test: Spatial footprint, density, homegeneity
Cleaning: SOR filter, density threshold (relative to the object and its size)
Indexing
if massive (>200M?) = Entwine
else .laz or .pnts
