Download FREE Geodata   GLOBAL, USA, Canadian, & Brazilian DEMs

---

All the TNT products¹ can convert all the 2D geodata layers in a view into stereo 3D. All that is required is access to one of the DEMs that can be downloaded here or your more accurate local DEM.

Select anaglyph mode if you do not yet have a full color viewing device. Select the active, passive, or autostereoscopic (i.e., glasses free) 3D mode used by your monitor or TV.

Assemble a view of any combination of georeferenced image, vector, CAD, shape, LIDAR, TIN, or pinmap geodata layers. Add Bing², web based standard tilesets³, or WMS layers. The DEM you select as your default will then be automatically resampled and used to redraw the 2D view in 3D. You can then use TNT's powerful editing tools to draw or edit layers directly on this 3D surface.

Each of these DEMs is a single, large TNT raster tileset object. Since a tileset is made up of many small files, each DEM file has been zipped to be downloaded as a single entity. It is not possible to download these in pieces, it's all or nothing. If you have difficulty maintaining a continuous download of a large files please try Filezilla as it will automatically resume an interrupted download.
