SLIC

SLIC is a simple location indexing service built with golang and persisted with redis. It's ingests lng/lats and returns a geoIndex. The geospatial indexing library being used here was built by uber h3 Feel free to use it.

What it does

It takes several coordinates and places them under an index, such that 1 index can point to numerous user ids.

What can you do with this (build upon this)

• You can build a realtime supply service for your ride sharing application
• You can build a realtime demand service for your ride sharing application
• Build a price surging system based on the number of id's in a particular geographical area (geo-index)

How to run

First Way

• go run server.go

Second Way

• go build server.go and then you run ./server
