EarthPositions
iOS Universel / Education
This app shows three animated functions about Earth positions:
1. Day and Night
This is the screen when you start the app. It shows a moving shape of the night zone over the Earth map, the time at different Earth positions and the city lights of the capitals or some large cities at night.
By default this animation shows the night shape for the current day and moves on from there. However, you can enter any date allowing you to observe how this night shape changes during the year and especially during the different seasons. E.g. on 21 of March, the night is exactly 12 hours long anywhere on Earth.
2. Earth and Sun
This animation shows how the earth orbits around the sun. During its orbit, it shows the date and shows a still picture at the change of the seasons. You can also enter a date to show it as a red dot marker on the orbit. By default, the animation shows the current date.
3. Where on Earth
A very attractive geographical game, where you have to guess a location on a 3D-Earth, which rotates and tumbles to display that location in the middle. This game contains 4 levels (beginner, skillful, advanced and expert), 5 continents (Africa, America, Asia, Europe and Oceania) and 4 groups (capitals, large cities, towns and airports). Depending on the game level, you can select your answer from a choice between 3, 6, 9 or 12 locations. You can get additional help by requesting up to three hints. However, a hint lowers the points you can earn when answering the question.
In addition to these main functions, a preferences section allows you to select a different language. You can choose between English, French, German, Spanish and Dutch. The preferences also show and keep track of the highest scores for the "Where On Earth" game.
And finally, the explain section shortly explains the functions of this app.
