About Mantle Place.

Mantle Place is a spatial data platform for real-world site context. You draw an area of interest on Earth, read its Site Brief, see the price before you pay, and keep the resulting bundle (terrain, imagery, CAD drawings, and more) in your vault. Paid bundles are yours forever. It is built for architects, engineers, and visualization teams, and anyone who needs a real site inside their tool.

No streaming subscription to keep a site working. No procurement conversation for a site model you can put on a card. No hunting across half a dozen agency portals for the pieces and stitching them yourself.

Not to be confused with MantlePlace, AssetMantle’s NFT marketplace.

Mantle Place LLC is a Minnesota-based company, founded by Coulter Heiberger, a visualization practitioner with industry experience in architecture, engineering, and construction.

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 keep their files. Paid bundles live in your vault permanently, and you can download them again at any time. If we change pricing, you keep your old bundles. If we go out of business, you have the files. You pay for the processing, not the data: free bundles (up to 2 km²) carry the exact same layers and quality, held for 30 days. Keep one by paying its normal price.

Pricing is honest, and you see it while you draw. $5 plus $2 per square kilometer, rounded up to the whole dollar, and up to 2 km² is free. 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 names its sources and licenses in its README and manifest, and your vault gives you the same list as a PDF and a JSON file. 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 map we host ourselves), open data sources (NAIP and Sentinel-2 imagery, OSM via Protomaps and Overture Maps, USGS 3DEP and Copernicus elevation), open-source UI primitives, open-source storage format. The importer itself is open source under Apache 2.0, public on GitHub. See the Attributions page for the full list.

v1 pulls from open-data sources, led by Protomaps (global vector basemap), NAIP (US aerial imagery at 1 m or finer), Sentinel-2 (10 m satellite imagery everywhere else, selected automatically), USGS 3DEP (elevation in the continental US, at 1 m wherever USGS lidar covers the site), Mapterhorn (Copernicus and national models) for coverage-aware elevation everywhere else, at 1 m across much of Europe, Overture Maps / OpenStreetMap (building massing and vector layers), and ESA WorldCover with Meta and WRI canopy data (land cover and trees). Every bundle manifest reports the true elevation resolution. US flood zones from FEMA come with US orders as a free public-record layer, outside the price and passed through as FEMA publishes them. Where we list a source, parcels and zoning come with the order too, free, along with federal records such as wetlands, historic places, and soils. v2+ candidates include imagery at 1 m or finer outside the US, a Cesium-for-Unreal-ready 3D Tiles output, and streaming delivery.
