I've put a short note up on bioRxiv about ways to geocode nucleotide sequences in databases such as GenBank. The preprint is "Geocoding genomic databases using GBIF" https://doi.org/10.1101/469650.
It briefly discusses using GBIF as a gazetteer (see https://lyrical-money.glitch.me for a demo) to geocode sequences, as well as other approaches such as specimen matching (see also Nicky Nicolson's cool work "Specimens as Research Objects: Reconciliation across Distributed Repositories to Enable Metadata Propagation" https://doi.org/10.6084/m9.figshare.7327325.v1).
Hope to revisit this topic at some point, for now this preprint is a bit of a placeholder to remind me of what needs to be done.
