Mantle Place vs OpenTopography & USGS 3DEP
The same public elevation, two different products: raw downloads for analysis, a finished site bundle for design tools.
OpenTopography and USGS 3DEP are the reference sources for United States elevation: authoritative, generous, and free to start with. 3DEP is free of charge and without use restrictions, and blankets the country at ten meters and finer; OpenTopography serves DEMs and raw lidar point clouds with research-grade provenance, free with an account and a free API key, with daily limits for non-academics and an OT+ subscription for more. If raw source data is what you need, start there. Mantle Place delivers what those portals deliberately do not: the finished product. In the continental US its elevation comes straight from 3DEP, but it arrives clipped to the exact area you draw and paired with aerial imagery and a vector basemap: the DEM as GeoTIFF, the mesh (glTF, OBJ), contours, and a LandXML surface arrive together and stay in the same permanent vault, at no extra cost. Same ground truth, minus the pipeline you would otherwise have to build.

Why Mantle Place
A product, not a portal
Portals hand you rasters and point clouds; the pipeline from there to something a design tool can open is on you. A bundle arrives clipped, meshed, and in the formats your tools read.
Elevation never travels alone
The same bundle pairs a vector basemap with aerial imagery draped over the terrain at the identical extent, so every layer lines up without a single reprojection step.
One surface, every format
The DEM GeoTIFF, the meshed glTF and OBJ, a heightmap, DXF contours, and a Civil 3D-ready LandXML surface all come in one bundle. One order covers the whole toolchain.
How they compare
| Dimension | Mantle Place | OpenTopography | Verdict |
|---|---|---|---|
| What you download | A finished multi-format site bundle | Raw DEM rasters and lidar point clouds | Raw data is the right starting point for analysis; a finished bundle is the right ending point for a design workflow. |
| Cost | One-time by area: $5 plus $2 per km², free at 2 km² and under | Free: 3DEP outright, OpenTopography with an account and daily limits | Free and authoritative is hard to argue with. What Mantle Place charges for is the packaging, pairing, and meshing, not the public data itself. |
| Lidar point clouds | Not offered | Raw point-cloud downloads at source density | If the deliverable is lidar itself (classification, canopy analysis, survey-grade inspection), OpenTopography is the right tool and Mantle Place simply does not compete. |
| Coverage | Global, coverage-aware: 1 m wherever USGS lidar covers the site, 30 m baseline elsewhere | Deep US lidar; global rasters like GLO-30 also hosted | Both reach worldwide for rasters; the difference is that Mantle Place resolves the best available source for your area automatically. |
| Imagery and basemap | Included, clipped to the same extent | Elevation-focused; imagery is not the product | Site context needs the ground texture and the streets, not just the heights. Pairing the layers is half the value of a bundle. |
| Ready for 3D / CAD tools | Meshed terrain, contours, LandXML, in the bundle | You convert the raster yourself | Between a DEM and a Civil 3D surface sits real conversion work; the bundle arrives with that work already done, at no extra cost. |
Frequently asked
Is Mantle Place elevation the same data as USGS 3DEP?
In the continental United States, yes. The elevation comes straight from 3DEP: 1 m wherever USGS lidar covers the site, otherwise the next-finest 3DEP product, and the delivered resolution is reported honestly in the bundle manifest. The difference is the product around it: clipping, meshing, imagery pairing, and formats.
Why pay for elevation that is free from 3DEP?
You are not paying for the data. You are paying to skip the pipeline: clip to your exact area, mesh for 3D tools, generate contours and LandXML, drape imagery, and keep it all re-downloadable in one vault.
Does Mantle Place deliver lidar point clouds?
No. Bundles carry a processed DEM, mesh, heightmap, contours, and LandXML, not raw point clouds. For lidar itself, OpenTopography is exactly the right place to go.
Do OpenTopography or 3DEP include aerial imagery?
No, they are elevation services. A Mantle Place bundle pairs the terrain with NAIP imagery at 1 m or finer in the US and a vector basemap, all clipped to the same extent so the layers align.
When should I use OpenTopography or 3DEP directly?
For research, spatial analysis, raw lidar, or any workflow where you want source rasters and full control of the processing. Free, authoritative source data is their entire mission.
