Contributing data to GLIMS and the RGI

If you have data to contribute to GLIMS (glacier outlines, center lines, snow lines, and the like), please let us know at This will notify people in both the GLIMS and RGI (Randolph Glacier Inventory) communities. We are increasingly flexible on the formats of data that we can accept.

If you are able, please format your data according to the GLIMS Data Transfer Specification (see here). This makes data ingest easy and minimizes the chance for error in reformatting your data. But at a minimum, please follow the guidelines in this document.
