# Coordinate Display

The Coordinate Display is a small live readout in the bottom left corner of the viewer that shows the latitude, longitude, and elevation of whatever your&#x20;mouse is hovering over in the scene. It updates as you move and is the quickest way to read off the location of a point without leaving a measurement\
behind.

### How to Use

click on the "Measure" button from the top bar.

click the "Coordinate HUD" button. The button highlights blue once the readout is on, and the small box&#x20;appears at the bottom left of the screen.

The readout shows three lines:

* "Lat" — the latitude of the point under your cursor, in degrees.
* "Lon" — the longitude of the point under your cursor, in degrees.
* "Elev" — the elevation of the surface under your cursor, in meters.

The readout follows the cursor so you can sweep over a feature in the scene and watch the numbers change. It reads off the actual surface, so if you hover&#x20;over a building rooftop or a 3D Tiles model the elevation reflects the top of that surface, not the ground beneath it. If the spot does not have a&#x20;tileset on it, the elevation falls back to the terrain height from the globe.

### How to stop

Click the "Coordinate HUD" button in the "Measure" panel a second time to turn the readout off. The readout also hides on its own when your cursor leaves&#x20;the viewer canvas, so it stays out of the way while you are working in side panels.

### Notes

The readout is a quick reference and not a saved measurement. If you want to keep a coordinate you can read here, use the "Coordinates" tool in the&#x20;"Measure" panel to drop a pin and store the value with the rest of your measurements.
