Maps3D sells imagery-draped 3D site models at a flat price per map; Mantle Place delivers the georeferenced site, priced once by area, free for small sites and ready for Unreal.
Maps3D and Mantle Place deliver close to the same thing: georeferenced terrain with aerial imagery and site layers for design tools. Maps3D exports a textured TIN terrain with buildings, roads, water, trees, contours, and parcels as glTF, OBJ, 3MF, STL, DXF, 3DM, SKP, or IFC in 260+ coordinate systems, at a flat price per map or on subscriptions, with prices shown for your location. Its baseline is 30 m terrain and 2.5 m AI-processed imagery, with finer regional data in the US, Europe, Canada, and Australia. Mantle Place delivers the site, priced once by area, free at 2 km² and under: aerial imagery at 1 m or finer across the US, the finest native elevation as a GeoTIFF DEM, vectors, with meshes and a LandXML surface and a free Unreal importer. Choose Maps3D for native SketchUp and Rhino models; choose Mantle Place for files you keep and Unreal.
Competitor details checked against maps3d.io, its pricing and its dataset page.
Cityweft lists Unreal among its tools, and so does Mantle Place, which also hands you the source data: each bundle carries imagery (aerial in the US, 10 m satellite elsewhere), the finest native elevation as a GeoTIFF DEM, and vectors on one georeferenced extent, with textured meshes and a LandXML surface. The free importer lands it in Unreal as a Landscape.
Mantle Place is free for any area of 2 km² or less, with the same imagery, elevation, and vectors as a paid order; free bundles stay in your vault for 30 days, or you can keep one for good at its normal price. Maps3D does not state a free tier on its pricing page.
A small site costs nothing and carries exactly the data of a paid order. Above that it is $5 plus $2 per km², published and shown before you pay.
The open-source Mantle Place Importer lands the bundle in Unreal as an editable Landscape with the imagery draped and the georeference applied. Maps3D names game engines in general but no importer.
Beside meshes, the bundle ships the GeoTIFF DEM, the imagery, and a vector basemap, so analysts, civil engineers, and GIS tools work from the same source the model was built from.
| Dimension | Mantle Place | Maps3D | Verdict |
|---|---|---|---|
| Pricing model | By area, published: free at 2 km² and under, then $5 plus $2 per km² | Flat per map or by subscription, shown for your location | A flat price favours large maps and a subscription favours frequent work; a published price by area favours small sites and budgeting before sign-in. |
| Imagery | NAIP at 1 m or finer in the US, 10 m Sentinel-2 elsewhere | 2.5 m AI-processed baseline, 8 to 60 cm in listed regions | Inside its high-resolution regions Maps3D’s imagery is sharper; across the rest of the US, NAIP at 1 m or finer is the stronger baseline. |
| Elevation | Finest native for the area, 1 m wherever USGS lidar covers the site | 30 m baseline, down to 25 cm in listed regions | Both reach fine national terrain where it exists; Mantle Place states the resolution it delivered for your exact area. |
| Design-tool files | DXF, OBJ, glTF, IFC, LandXML, USDZ, and more | glTF, OBJ, 3MF, STL, DXF, 3DM, SKP, and IFC | Maps3D writes native SketchUp and Rhino files; Mantle Place adds Civil 3D, GIS, and an Unreal importer. |
| Site layers | Vectors, building massing where mapped, and more | LOD1 buildings, LOD2 in some countries, trees, parcels | Maps3D models more of the streetscape out of the box, including trees and parcels in its listed regions. |
Yes. Both deliver georeferenced terrain with imagery for design tools; Mantle Place adds a published price by area, a free tier at 2 km² and under, the source GeoTIFF DEM, and an Unreal importer.
Maps3D sells one map at a flat price that does not depend on area, or subscriptions with unlimited exports, with prices shown for your location. Mantle Place is free at 2 km² and under, then $5 plus $2 per km², paid once.
Yes. Maps3D exports in UTM, State Plane, national grids, and more. Every Mantle Place layer shares one real-world extent and coordinate reference, so the site lands in place beside survey and GIS data.
When you want native SketchUp or Rhino models with trees and parcels, the site sits in one of its high-resolution regions, or you need large maps often enough that a flat price or a subscription pays off.
Draw an area and see it in a free Site Brief before you pay. Download a bundle for Unreal, Revit, Civil 3D, QGIS, and more. Every format is built with your order, at no extra cost. $5 plus $2 per km², and 2 km² and under is free. Paid bundles are yours for good. Free bundles keep 30 days, or keep one permanently at its normal price.
