A few simple things that will help you get the most from LibreAtlasLibreAtlas is a simple application mainly intended for teaching and learning about Geography.
Think of the LibreAtlas application as a player/viewer of geography information. That information needs to be provided in the form of a LibreAtlas database. Don't be worried, there is absolutely nothing complex in this. A LibreAtlas database is just a file that you place somewhere on your hard disk, then open with LibreAtlas.
So to get started, you simply:
- install the LibreAtlas application
note for Windows users: "to install" in this case simply means "just copy somewhere", no complex installation is required.
- download or copy a LibreAtlas database of your choice
- when starting the application for the first time, you open the LibreAtlas database
- and that's absolutely all!
More about the LibreAtlas databasesYou can find any relevant information on the specific Wiki pages: WorldAtlas, ItalyRailAtlas, PiemonteAtlas and LunarAtlas
A very quick how-to tutorial
|Menu and toolbar|
|Zooming and panning|
|While moving the mouse on the map, if some relevant geographic feature is detected at the corresponding coordinates, a small tip will appear; and the intercepted feature will be evidenced on the map.|
maritime areas on-the-fly detection
i.e. seas, oceans, gulfs and alike
land areas on-the-fly detection
i.e. mountain ranges, plains and alike
hydrography on-the-fly detection
i.e. rivers, lakes and lagoons
Country on-the-fly detection
Town on-the-fly detection
When the Identify tool is selected, performing a mouse click (left button) on some land map area will cause Country identification.|
i.e. a small dialog box will appear, reporting several general infos about the intercepted Country, this including the National Flags and the National Emblem / State Seal.
When the Graticule tool is selected, Meridians and Parallels will be shown over the map.|
And On-the-fly identify will be applied all times that a Meridian or Parallel is intercepted.
When the Distance tool is selected, you can measure the distance between two points on the Earth's surface.|
Each mouse click (left button) will select a point.
Each time that a pair of points is selected, the corresponding distance will be shown on a dialog box, and the geodesic path will be shown over the map.
Please note: Planet Earth is a sphere (not exactly, it's a geoid, quite approximating an ellipsoid).|
So minimum length paths does actually follow Great Circle aka Geodetic lines.
|So please don't be surprised if geodetic lines do not look at all like straight lines.|
