Location view

This view displays a map of the selected location. The eclipse centerline, totality northern and southern limits are drawn on the map, along with direction lines for the eclipse contacts, if any.
The map can display a standard roadmap, a satellite view, or a mix of both. You can zoom in and out, and drag the map around. The arrow button at top re-centers the map on the selected location.
The map view is currently disabled on the GPL release, due to Apple MapKit restrictions.
Using the bookmark button at top opens the location bookmarks window to save the current location, or restore a previously saved one.
The search field allows to look for a location by name.

The bottom frame of the view allows to:

• Enter your location latitude, longitude and altitude,
• Set the time-zone and daylight saving time,
• Or lock on the current position, either:
  • from a GPS receiver, connected through a serial line using the NMEA protocol, to continuously update your location and time. Some information about the GPS receiver connection and time quality is also displayed.
  • or without an external GPS receiver, from the macOS location services, if you allow it.

When locked on GPS, the GPS square bulb is displayed green while the GPS connection is established, or red when the GPS connection is broken.

To be able to update your location and time from an external GPS receiver, you have to select a serial line in the preferences :

If you need to change some "advanced" settings of the serial line, select the "expert" disclosure triangle :

For the basic and expert settings, refer to your GPS receiver manual for the right values.

If you do not lock your location and time on an external GPS receiver, your computer time shall be perfectly synchronised, for Sciatrope eclipse circumstances to be reliable.
If your computer was connected to the internet some days before the eclipse (and configured to set its time from a net time server - this is the default on macOS) it should be enough.
