## What it is
MAPS.ME is an open-source cross-platform offline maps application built on OpenStreetMap data, with the core engine written in C++ and apps for iOS and Android. The repository contains the full map rendering, search, and routing engine plus tools for generating map files and styles.

## Use cases
- use offline maps without an internet connection
- navigate with turn-by-turn directions using OpenStreetMap data
- build custom map files for regions
- customize map styles for an offline maps app
- embed offline map search and routing in a mobile app

## When to choose
- you need fully offline maps and navigation on iOS or Android
- you want an open-source OpenStreetMap-based map engine to fork or embed
- you need to generate custom MWM map files or map styles

## When to avoid
- you need a lightweight map SDK for a web frontend
- you require actively maintained upstream releases
- you need online-only features like live traffic

## Facets
- artifact type: application
- maturity: maintenance
- function: geospatial, search-engine, routing, gui
- domain: mobile-development, cross-platform, travel
- platform: cpp, cross-platform
- tags: offline-maps, openstreetmap, navigation, map-rendering, routing, maps, android, ios, mobile
