Example: Making a Safe Spot
You can use a close up view of a system when you are making safe spots for exploring or scouting. In the first image I have zoomed the map in to look at the system I am in. To make it easier to see things in this example, I have also turned off all of the marker icons except for stargates and personal location. The circle with the X in it marks the location of my ship.

What I am going to do to make the safe spot is warp from here to the farthest stargate - and while doing this I am going to drop a location marker about halfway across the system.
So first I right click on the stargate I want to use, which brings up the action menu, and then I press the key for "New Location", which brings up the location box.
Having done that, I then jump to within 100 K of the gate. On the map I will see my ship move across the system. When the moving X gets to the place where I would like to have a safe spot, I click "Submit" on the Location box.

In the final image you can see that my ship is over by the stargate. And you can see where I dropped the location marker. And of course, this location now also appears in my "People and Places" window.

If I need another safe spot, I can go back to this location and repeat the process while jumping to a moon, planet or one of the other gates. This process leaves location markers that are not directly between two gates, and thus are relatively safe.
