## What it is
map3d is a web application that generates real-world 3D city maps with buildings and roads using React-Three-Fiber and OpenStreetMap data. It supports exporting the generated 3D scenes as GLB files for use in digital twin, drone surveying, and GPS marker applications.

## Use cases
- generate a 3D map of a city from OpenStreetMap data
- export city buildings and roads as a GLB model
- build a digital twin of a real-world location
- visualize building footprints and road networks in 3D
- create GPS marker overlays on a 3D city map
- prepare 3D city models for drone surveying

## When to choose
- you need a free, browser-based tool to turn OSM data into 3D city models
- you want GLB export for use in other 3D engines or tools
- your project is built with React and Three.js and needs map geometry

## When to avoid
- you need guaranteed-accurate building heights, since OSM data may be missing or wrong
- you need textured or photorealistic buildings (not yet supported)
- you need offline or self-hosted map generation without a web interface

## Facets
- artifact type: application
- maturity: active
- function: graphics, data-visualization, geospatial
- domain: web-development, graphics
- platform: browser, cross-platform
- tags: 3d-map, react-three-fiber, threejs, openstreetmap, glb-export, digital-twin, maps, web-server
