This is an application that displays satellite images of whole earth in Azimuthal Equidistant projection centering on arbitrary points.Directions:Double tap: Move the center of projection.Pan: Translate maps　(only in the translation mode). Revolve maps around the center of projection (only in the rotation mode).Pinch: Zoom in or zoom out on maps　(only in the translation mode).The button on the right side of the navigation bar: Switch between the translation and the rotation mode.Long Press on the map: Display the shortest path between the center and the long-pressed point. Also, calculate the azimuth clockwise from North and the distance between these points, and show them in a text view. When tap the text view, the text view and the path disappear.Settings view:- Center of projection can be specified in either of the following ways: entering longitude and latitude manually, selecting a city from a list of cities, getting the user's current location.- Select the unit of distance: kilometer (km), mile (mi), nautical mile (nm).- Show/Hide lines of latitude and longitude.- Show/Hide boundaries of countries.- Show/Hide names of major cities.- Show/Hide major airports.
