Source of DEM in gCarta / GeoFlyer 3D Maps?

Where does gCarta / GeoFlyer 3D Maps have their DEM data from?

On their website they only say highly-detailed 3D terrain, but not the source. I have asked them already, but didn’t get an answer. And there is no article or information about this nice to view (but difficult or complicated to use/move around) app in the OSM-Wiki.

The map data is from OpenStreetMap.

Advantage of this app: really detailed digital elevation model data.
Disadvantage: no vector data for the ways, only for the names of some POIs, rest is raster graphics

Not sure if this is really related to OpenStreetMap but I found under https://geoflyer3dmaps.com/features/:

"geoflyer reproduces the terrain in 3D with stunning details, using the best available digital elevation models from NASA, from various European mapping agencies (Europe), from USGS (US & Canada)."

Ok, haven’t found that. Thought they might have acquired their data directly from https://en.wikipedia.org/wiki/TerraSAR-X which has the best resolution of 1 m.
