These tools accessed from the the upper left portion of the map as shown in the image. See the “Show Nearby AIS Tracks” article for information on the last icon in the list ().

Zoom

To zoom in or out on the map, users can use the and buttons in the top left of the screen. You can also use the scroll function on your computer mouse/track pad to zoom in and out. 

Specific Points on the map

Sometimes it’s helpful to be able to zoom into a precise area of the Skylight map based on coordinates. Using the zoom buttons can get you close, but manipulating the Skylight URL is a more precise option.

https://sc-production.skylight.earth/#<zoom level>/lat/long

For example in the screenshot the URL is:

https://sc-production.skylight.earth/#4.77/-3.13/156.27

Zoom level = 4.77

Lat = -3.13

Long = 156.27

Editing these values will take you a different place on the map. 

Zoom levels are #1.5 (the most zoomed out; this is the default Skylight view) to #22 (most zoomed in).

You can also see where your cursor is on the map using the coordinates in the bottom right hand portion of the screen.
