Anywhere on Earth
Global elevation and OpenStreetMap mean the same workflow in Tbilisi, Lisbon, Lagos or Lima — no coverage map to check first.

Platform
One workspace from the first look to the base drawings.
No hunting for data in ten portals: terrain, context, analysis and drawing in one place, in metres.
All featuresLive 2D and 3D preview
Contours, buildings, roads, water and terrain on the map before you export. Switch to 3D to read the slope of the site.
Site analysis board
Figure-ground, heights, uses, walking distance, noise, sun, shadow and wind diagrams drawn from the data, with legends and scale bars.
Georeferenced or local
UTM coordinates for surveys and GIS, or a clean local origin for modelling. IFC files carry their map conversion.
Site plan editor
Draw the proposal in metres with CAD precision over the real surroundings, then download a vector sheet or a rendered presentation.
CAD, BIM and 3D print
DXF on named layers, true-scale PDF and SVG, IFC, OBJ and watertight STL. Projects, imports and saved files stay in your account.
Workflow
From a place name to CAD in four steps.
STEP 01
Pick the site
Search a place, then draw or type the area — up to 150 km².
STEP 02
Tune the layers
Contours, buildings, roads, water, vegetation and trees. The preview follows your settings.
STEP 03
Cut and analyse
Two clicks for a section; sun, wind and site diagrams from the same model.
STEP 04
Export
Any formats in one ZIP with coordinates and sources documented — or keep it in your files.
Site sections
Cut through the landscape in two clicks.
Draw a line across the site and TOPOLUMA builds a true section: the ground profile, buildings cut by the plane, buildings and trees behind it in elevation, water levels, and where roads and rivers cross.
- Vertical exaggeration from 1× to 10× with an honest datum
- Choose which side you look towards and how deep the elevation goes
- Hover the profile to read distance, elevation and slope
- Export each section as DXF, PDF, SVG or a CSV of the profile

Is TOPOLUMA free?+
Yes — the studio and all exports are free while TOPOLUMA is in beta. An account is only needed to save projects, keep files and an export history.
Where does the data come from?+
Elevation comes from Mapterhorn, which combines the Copernicus GLO-30 model (about 30 m, worldwide) with more than a hundred higher-resolution national models, with Terrain Tiles on AWS as a fallback. Buildings, roads, water, vegetation and trees come from OpenStreetMap. See the data page for details.
How accurate are the contours?+
Outside countries with open lidar the elevation grid is typically 30 m, so contours describe the general shape of the land well but will not show retaining walls, terraces or small earthworks. For design development and approvals you still need a site survey.
How large can an area be?+
Up to 150 km² per export. Dense city centres export fastest below about 4 km².
Which coordinate systems are supported?+
Local coordinates with the origin at the south-west corner or the centre of the area (true north up), or the UTM zone of the site (WGS 84). 3D models always use local coordinates; IFC adds a map conversion to UTM.
Can I use the exports commercially?+
Yes. OpenStreetMap data is licensed under the ODbL, which allows commercial use as long as you credit “© OpenStreetMap contributors”. Every export includes the attribution.
Which software can open the files?+
DXF opens in AutoCAD, BricsCAD, ArchiCAD, Revit, Vectorworks, Rhino and SketchUp Pro. OBJ and STL open in almost every 3D tool and slicer. IFC opens in ArchiCAD, Revit, BlenderBIM and any IFC viewer.
