Actually, these countries tend to adopt European standards, but there are no such in the field of civil engineering yet. I am not a civil engineer although I made a few road projects for them and my final product is usually 3D visualization of site.

Airbus Defence and Space has officially launched its WorldDEM Digital Terrain Model (DTM), a highly accurate standardized representation of bare Earth elevation that can be made available for any point on the globe. This addition completes the WorldDEM portfolio enabling Airbus Defence and Space to provide both surface and terrain elevation information, in support of global customer projects. WorldDEM is based on data acquired by the high-resolution radar satellites TerraSAR-X and TanDEM-X, which started synchronous data acquisition in December 2010 and completed coverage of the Earth’s entire landmass twice over in mid-2013. The satellites covered more complex terrain areas with a third and fourth acquisition campaign to ensure consistent high quality and accuracy of the final product. WorldDEM provides the first global, single-source, high-precision Digital Surface Model and has established a new standard of global elevation models. · Digital Terrain Models (DTMs) based on WorldDEM are now commercially available · WorldDEM DTM can be delivered for over 90 Million km² of the Earth’s landmass source : http://gisuser.com/2015/04/airbus-defence-and-space-launches-worlddem-digital-terrain-model-the-new-bare-earth-elevation-model/
