Flat Earth - Satellite Image Viewer|交通運輸線上App不用買-HotApp4Game

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 left side of the toolbar: 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.Tap the page curl button in the lower-right corner:- Show/Hide lines of latitude and longitude.- Show/Hide boundaries of countries.- Show/Hide names of major cities.- Show/Hide major airports. (Their names are visible when zooming in.)- 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).This application uses the satellite images obtained from NASA's web site.The maximum resolution of satellite images in this current version is 4/480 degrees per pixel. This application can be used in offline environment, but will be more limited in resolution.Credits:Blue Marble: Next Generation was produced by Reto Stockli, NASA Earth Observatory (NASA Goddard Space Flight Center).
