About georeference.it
georeference.it is an open-source crowdsourcing platform for georeferencing natural history collection specimens from GBIF.
Millions of biodiversity records in GBIF — particularly those from natural history collections — lack geographic coordinates. This makes them invisible to spatial analyses and conservation planning.
Our platform allows volunteers to place these specimens on the map, following the Georeferencing Best Practices (Chapman & Wieczorek, 2020). A consensus-based validation system ensures quality: georeferencing suggestions accumulate votes from experienced contributors until a confidence threshold is reached.
Standards-based
All georeferencing output uses Darwin Core terms and follows the Georeferencing Quick Reference Guide.
API access
Publishers can download validated georeferencing data via our API to enrich their GBIF datasets.
