About Mantle Place.

Mantle Place is a spatial data platform for AECO professionals: architects, engineers, construction managers, and operations / land-development teams. You draw an area of interest on a globe, see a deterministic price, pay, and own the resulting bundle — terrain, aerial imagery, vector basemap, building massing where mapped, and structured vector layers — in a Cloudflare R2 vault. Purchased bundles are yours forever.

No streaming subscription that vaporizes on cancellation. No procurement conversation for a $20 site model. No hunting across NAIP STAC + Mapterhorn + Protomaps for the pieces and stitching them yourself.

Mantle Place LLC is a Minnesota-based company, built by a visualization practitioner with AEC industry experience.

It started as a personal frustration: site-context data for visualization and early-design work was fragmented across half a dozen agency portals, gated by opaque licensing, and shipped in formats that didn't drop cleanly into Rhino / Revit / Blender / Unreal. Mantle Place is the version of that workflow that should have existed.

Curators own what they buy. Purchased bundles live in your R2 vault permanently, with re-mintable presigned download URLs. If we change pricing, you keep your old bundles. If we go out of business, you have the files. Free bundles (2 km² and under) carry the exact same data and quality, held for 30 days — buy a site to keep it.

Pricing is honest and computable at draw time. A floor plus a per-km² curve. No metering, no usage tiers, no per-seat math. You see the price before you commit.

Licensing is visible at the decision point. Every bundle ships with an attribution PDF and a machine-readable attribution JSON. The full Produced Works architecture is on the Licensing page.

The stack is open as far down as we can take it. Sovereign basemap (Protomaps planet PMTiles mirrored to R2), open data sources (NAIP and Sentinel-2 imagery, OSM via Protomaps and Overture Maps, Copernicus via Mapterhorn), open-source UI primitives, open-source storage format. See the Attributions page for the full list.

v1 pulls from five open-data sources: Protomaps (global vector basemap), NAIP (sub-meter US aerial imagery), Sentinel-2 (10 m satellite imagery everywhere else, selected automatically), Mapterhorn (global coverage-aware elevation — 1 m across most of the US and much of Europe, with the true resolution reported in every bundle manifest), and Overture Maps / OpenStreetMap (building massing and vector layers). v2+ candidates include commercial sub-meter international imagery, FEMA flood hazard, a Cesium-for-Unreal-ready 3D Tiles output, and streaming delivery. The full roadmap lives in the manifesto.
