alt Hacker NewsI get the latitude, longitude, and they added time. But what was the fourth dimension? Or third rather, because the post assumption is that time was the fourth added.

The lat and lon are actually 3d since we live, up to a first approximation, on the surface of a sphere. The correct way to think about it is xyz in a reference frame anchored in the center of the Earth

The fourth is altitude. I asked a colleague how he found Vietnam. I was surprised to hear him say it said it was windy, desolate, and cold as hell. It did not match my experience at all. Turns out he had been hanging out at 30 000 feet the whole time!
Altitude is the third dimension, but I presume you knew that.
"Geography is three dimensional" doesn't correctly communicate the time dimension.
