Locations Editor
The Locations Editor manages the shared library of geographic locations that every study draws on. Because a study shows its records in the location's time zone, a location is required before any ephemeris can be generated.
To open the Locations Editor:
- Click Edit → Locations on the menu bar.
You can also click the Locations button on the toolbar. Locations are edited in a table; when you are finished, click Save.

Location Columns
| Column | Description |
|---|---|
| Name | A descriptive name for the location, such as "New York, NY". |
| Latitude | Geographic latitude in decimal degrees, from -90 to +90 (positive is north). |
| Longitude | Geographic longitude in decimal degrees, from -180 to +180 (positive is east). |
| Height (feet) | Elevation above sea level in feet (0 is sea level; a negative value is below sea level). |
