9月8日的Jupiter Atlas应用程序分析

Explore 3D globes of Jupiter's Galilean moons Use pinch and finger gestures to manipulate a 3D globe of one of four of Jupiter's Galilean moons. As you zoom in more labels appear as finer detail comes into view. You can double tap on the labels to get more information about a particular feature. Jupiter Atlas displays the approximate phase, axial tilt and central meridian of the selected moon from your chosen location and time, and renders these on the globe. You can switch to a 'Globe' mode that allows you to spin the moon around to see the whole globe. The feature database is searchable and can move the globe to a searched feature. The phase can be switched off to show the whole globe more clearly. The moon's globe can be shown with north or south at the top or inverted to suit different telescope views. Over 680 named features across four moons are included. These moons are Io, Europa, Ganymede and Callisto. The phase view shows the current view of Jupiter itself including the position of the Great Red Spot and the approximate axial tilt and central meridian. You can swipe left and right on the phase view to go backwards and forwards a day. When you turn the device to landscape mode a wider view is shown with the Galilean moons in their approximate positions for the time selected. Date, time and location can be changed. There is also a realtime mode that will update to the current time. Atlases for the Moon, Mars, Mercury, Venus and Saturn are also available on the App Store!
