Symbiota Collections of Arthropods Network (SCAN): A Data Portal Built to Visualize, Manipulate, and Export Species Occurrences
The Symbiota Collections of Arthropods Network (SCAN) serves specimen occurrence records and images from over 100 North American arthropod collections for all arthropod taxa. The focus is on North America but global in scope. SCAN is built on Symbiota, a web-based collections database system that is used for other taxonomic data portals, including (Symbiota Portals). SCAN is the primary repository for occurrence data produced by the three continuing Thematic Collections Networks (TCNs), the Southwest Collections of Arthropods Network (SCAN TCN), the Lepidoptera of North America Network (LepNet TCN), and arthropod data produced by InvertEBase TCN. InvertEBase serves occurrence data for mollusk and other non-arthropod taxa. We also host observational data, the largest data provider is iNaturalist. Each collection is primarily responsible for their data and we have structured the database to make it easy to include collections of interest when querying the database.
Important features of all Symbiota portals include:
The key organizational feature is that each museum or project is listed as a separate collection, so that one database group does not interfere with another. End users can select all "collections", or just a subset. This website is the central data portal for SCAN; all other project information can be found on the LepNet WordPress site, including How-To-Guides and network updates.
SCAN currently serves over 18 million records for 238,177 species, and 2,276,630 specimen/label images (7/16/18).
