node-red-node-geohash

A Node-RED node to encode and decode lat,lon pairs to a geohash string.

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-node-geohash

Usage

This function encodes a lat,lon string to and from a geohash.

If the msg.payload is a string it tries to see if it's a geohash - if so it tries to decode it and outputs a payload object containing

  • latitude
  • longitude
  • errorlatitude
  • error.longitude

If the msg.payload is an object with properties lat or latitude and lon or longitude - it will add a geohash property to the payload.

The precision can be set by msg.payload.precision from 1 to 9.
