Bmap

Hosted web tool that builds a low-poly 3D model of any place on Earth from a box drawn on a map, with terrain, buildings, roads, coastline and trees from open geographic data.

What is reusable: closed sourceopen dataAPI unknownunknown participation Built from open data (OpenStreetMap, Overture, Copernicus GLO-30, IGN, ESA WorldCover); the site says the pipeline itself is kept private.

The user searches a city or drags a box, and Bmap assembles the land surface, the coastline, the buildings at their footprints and heights, the road grid and the tree cover, all at 1:1 scale.¹ The result spins in the browser and can be exported for use elsewhere.¹ The site's worked example is Monaco, built up in stages: terrain, then coast, then buildings, then waterfront.¹

It is aimed at people who want a real place as a game or web scene without GIS software or hand modelling,¹ and exports a layered GLB file, a single-file 3D format that three.js, Unity and Blender read.¹ Unreal Engine 5 appears as an export in both paid plans in the pricing table, but elsewhere the page names it and Roblox as next in line.¹ The app page offers Nice, Monaco, Antibes and Genoa as starting points and a default area of 3.5 km.²

The service is hosted at app.bmap.io, and the pipeline that builds the models is kept private.¹ The underlying data are open, credited to OpenStreetMap contributors under the ODbL licence, Overture Maps, Copernicus GLO-30, the French mapping agency IGN and ESA WorldCover.^1,2

Free: unlimited generation of maps up to 1.5 km, with a browser preview and walk mode.¹
Single export: $29, with a commercial licence.¹
Creator plan: $49 a month for maps up to 5 km, ten exports a month and editing tools.¹
