The company behind the Bitcoin map is called coinmap. They did make an announcement here some years ago:
A lot of the data comes from OpenStreetMap, where you can just tag any business with this code:
Key:payment
Bitcoin tagging for businesses/nodes has been discussed on the tagging mailing list but maybe not yet voted on:
payment:bitcoin=yes Bitcoin accepted as a payment method at the Point/Points of sale.
payment:bitcoin=no Bitcoin is not accepted.
payment:bitcoin=interval Bitcoin is accepted only at certain times; the notation for opening_hours=* can be used.
payment:website:bitcoin=yes Bitcoin accepted through a business's website yes. If it is not, then choose no.
