Geohashing Chat by User Proximity Tutorial
This geohashing user proximity tutorial walks you through how to build a real-time JavaScript chat app that connects users based on relative location (i.e., geohashing). To connect groups of two or more people by location, you must take latitude/longitude values and reduce accuracy resolution. By doing this, you can expand the coverage of proximity. You can use multiple resolutions at once or a fi
Location aware matchmaking with redis
Location stuff is cool! So let’s build a system that takes a person’s latitude and longitude, and returns the location of someone nearby. Tools I’m going to use Redis to store the locations of people connecting, and the python-geohash library, but more on that later. Redis is well suited to the task of being an index/store for matchmaking, as the data is usually transient, and therefore badly suit

GitHub - michilu/geohash-js: GeoHash Routines for Javascript
Geohash Javascript Demonstration (c) 2008 David Troy Released under the MIT License SUMMARY This is a basic demonstration of how the GeoHash algorithm can be used to generate bounding box searches without the use of specialized spatial indexing approaches. This can be especially helpful in cases where spatial indexes are either not supported or do not scale to high volumes. Environments such as Go
