In plain words
Geohash.world is an API tool for developers that encodes and decodes geographic coordinates using the Geohash algorithm. It allows users to convert between standard latitude-longitude coordinates and compact Geohash strings, which are useful for spatial indexing and proximity searches. The service is designed for developers building location-based applications who need reliable coordinate conversion functionality.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.

That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
