DESCRIPTION
http://dx.doi.org/10.1145/2345316.2345355 Modern field science, including archaeology, utilizes a mas- sive amount of digital data captured by state-of-the-art mea- surement instruments. Large archaeological data sets may include images, geospatial data, analytical data, and meta- data. Geospatial information plays a central role in the life cycle of those data; information is collected, organized, and published for analyses and visualization as final output us- ing geospatial data as an index. The web is an ideal place to publish scientific data and promote diverse collaboration, and thus we need a system to publish digital archaeologi- cal data efficiently so that it is also integrated in our data management workflow. In order to realize this goal, we designed and implemented a web-based application named ArcheoSTOR Map, which visualizes and publishes raw ar- chaeological data onto a map.

Overview
• “Big Data” in digital archaeology
• Workflow of field research data
• Visual analysis on ArchaeoSTOR Map
Digital Archaeology Concept
Big Data
• Volume
• Velocity
• Variety
Variety of Data
• Site data
• Images, geospatial data, and metadata
• From cameras, total stations, LiDAR
Variety of Data
• Artifact data
• Images, analytical data, and metadata
• From cameras, XRF, FTiR
Role of Geospatial Data
• Every site has 3D vector and point cloud data.
• Every artifact has geospatial context.
• Field research data can be indexed by geodata.
Data Liberation
• Scientific data should be made public.
• Web is an ideal place to publish data
• Universally accessible
• Promotes collaboration
