# latlon.art

> An archive of transients by Peter Semmelhack.

A transient is one point in spacetime: latitude, longitude, altitude, and a UTC time. Those four together are the TID. A missing field is left out. It is not zero.

The HTML works without JavaScript. /map is the only page that loads a script.

Draft records are pending Petrus's review. Do not treat a blank as a measurement.
