Geocoding is a basic spatial referencing process that is extensively used to connect scientific data to a specific location on Earth. Currently there is a gap in knowledge about using culturally responsive geocoding practices that align with the Indigenous Data Governance framework when working with Indigenous digital heritage data. This mixed methods project closes this gap by applying the Indigenous Data Governance framework to geocoding Indigenous heritage data in the Arctic. The project enables knowledge translation by producing ethical best practice guidelines based on geocoded data from Arctic Indigenous museum collections and Indigenous data on complex human-environment interactions from collections that are currently in the care of heritage institutions in the Midwest, and originate in Alaska Native communities in the Kawerak region of Alaska.
