## What it is
Xaddress is a Ruby library and CLI that encodes latitude/longitude coordinates into a human-readable, address-like format that can be decoded offline with pen, paper, and a physical map. It includes a visual avatar for error checking and a short code suitable for links and storage.

## Use cases
- convert lat/long coordinates into a readable physical address
- decode an Xaddress string back into coordinates offline
- give people in low-tech environments a usable address
- generate short location codes for sharing links
- verify a written address is correct with a visual avatar
- encode locations without a geocoder by specifying state and country

## When to choose
- you need offline, low-tech address encoding and decoding
- you want an open-source alternative to What3words
- you need error detection when addresses are transcribed by hand
- you work in Ruby and want a simple CLI or library for coordinate encoding

## When to avoid
- you need high-precision coordinates beyond ~10 meter accuracy
- you need a maintained service with guaranteed geocoding API availability
- you need integration in languages other than Ruby
- you need an actively developed project with recent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: geospatial, cli, parser, sdk
- domain: developer-tools
- platform: ruby, cli, cross-platform
- tags: geocoding, address-encoding, what3words-alternative, offline-addressing, latitude-longitude, human-readable-coordinates, maps, geospatial, command-line
