12. Map Display
12.1. Map Layers
Little Navmap uses two layers to display the map.
12.1.1. Background Map Layer
This is defined by offline or online maps like the OpenStreetMap. You can change the background by selecting another Theme. The background maps cannot be modified or configured since they are fetched from third party online services. Little Navmap downloads pre-rendered image tiles from these services to draw the background map.
12.1.2. Foreground Map Layer
The foreground layer which is drawn by Little Navmap and can be customized in the options dialog on the map pages. It consists of airports, navaids, airways, airspaces, userpoints, measurement lines, range rings, holds, traffic patterns, MSA diagrams and all moving objects like AI and the user aircraft. This layer reflects airports as stored in the scenery library of your simulator. This applies to stock and add-on airports.
Only this layer provides the objects which enable tooltips and the functionality of the context menus to build a flight plan.
See Mouse Clicks and Key Commands in the map legend for information about how to move around the map using the mouse or keyboard.
Do not forget to activate the map window by clicking into it or pressing
F2 before using keys for movement.
12.3. Mouse Clicks
A single click shows details about all map objects at the clicked
position in the
Information dock window. Windows and tabs are raised
depending on clicked objects.
The procedure search window can be raised optionally if clicking an airport.
This can be enabled in the options dialog on page Map. Check
Show procedures on airport
click to enable this function.
A single click on an user aircraft, AI aircraft or multiplayer aircraft
shows details in the
Simulator Aircraft dock window.
A double-click zooms in showing either the airport diagram or the navaid
closely and also shows details in the
Information dock window. The
same applies for all AI or multiplayer aircraft or ships.
The double-click and single-click functionality does not work for flight
plan waypoints or airports if the flight plan edit mode is enabled. The
edit mode can be disabled using the toolbar or
Flight Plan ->
Edit Flight Plan on Map in the main menu. See also Map Flight Plan Editing.
The mouse click sensitivity can be adjusted in the
Options dialog on
the page Map Navigation.
The center of the airport symbol is the hotspot for right or left click actions as well as for tooltip display. This is also the case if the whole airport diagram is visible.
The same applies to all navaids as well as airport parking spots where the center is the hotspot for clicks.
12.4. Mouse Click Hotspots
Map marks like range rings or measurement lines have hotspots to indicate that a modifier-click
Ctrl+Click can remove them or an action is available in the context menu. The same applies
to the flight plan drag and drop editing mode.
The mouse cursor changes into a hand to indicate a click spot.
Click spots and hotspots for tooltips are:
Center of all airport, airport parking and navaid symbols.
Navaids for the procedure preview (Preview and Highlights).
Center of range rings (small circle).
Center of MSA diagrams (small circle).
End of a measurement line (cross).
Runway threshold point (small circle) for airport traffic patterns.
Holding fix (small triangle) of a user holding.
12.5. Mouse Clicks and Modifiers
You can use the keyboard and mouse clicks to get quick access to some functions.
See Mouse Clicks in the map legend for more information about this.
Clicking again on a hotspot removes the mark, measurement line or flight plan waypoint, for example.
The user aircraft and AI or multiplayer aircraft or ships will be shown on the map if the program is connected to a flight simulator. Color indicates user or AI or multiplayer vehicle and the symbol shape indicates if the aircraft is an piston/turboprop, jet, helicopter or a ship. The symbol outline changes to gray if an aircraft is on ground.
Note that not all simulators and online networks provide enough information to show the correct aircraft shape.
Little Navmap limits the display of AI vehicles depending on size. Zoom close to see small aircraft or boats
AI and multiplayer aircraft on ground are shown only on small zoom distances to avoid cluttered airports. This means that an AI aircraft can disappear from the map when landing on an airport.
Labels are shown depending on zoom level and distance to user aircraft as well. Zooming out drops the less important aircraft labels, for example. Flight number and registration are always shown.
A yellow wind arrow and labels for the situation around the user
aircraft can be displayed on the top center of the map. The displayed
labels for aircraft can be configured in the dialog
Map Display Labels. No labels are shown for ship traffic.
See Aircraft and Ships for details about the aircraft type.
On the lowest zoom distance all aircraft are drawn to scale as are the parking spots which means you can easily check if your aircraft fits on an apron, parking spot or taxiway.
Hovering the mouse over the map will show tooltips for all map objects
including airports, VOR, NDB, airways, parking, fuel box, towers,
aircraft and ships. The tooltip is truncated and shows a message
More ... if it gets too long. In that case reduce details or zoom in
Verbose tooltips in options on page Map if you do not like the large tips.
The sensitivity for the tooltip display can be adjusted in the
Options dialog on Map Navigation.
You can select which tooltips to show in options on page Map.
Airports, navaids or other features that are selected in the flight plan table or in a search result table are highlighted on the map with a green/black or a yellow/black ring respectively (colors at default settings).
Waypoints that are selected in the procedure preview are highlighted with a blue/black ring using default colors.
These highlight circles provide all functionality of visible map objects, even if the objects are not shown at the current zoom distance (ring is empty). This allows double-click for zoom in, single-click for information dock window and all context menu entries.
You can use
Map -> Remove all Highlights and Selections to remove all
highlights from the map.
Colors and appearance can be customized in options on page Map Display User.
12.9. Flight Plan
You can enable or disable the display of the flight plan as well as missed approaches in the menu and toolbar.
All features which are part of the flight plan are forced to be shown even if they are disabled in the menu. This means that destination, departure and alternate airport symbols as well as diagrams are shown even if airport display is disabled. The same applies to all navaids and approach ILS.
Colors and appearance of the flight plan can be customized in options on page Map Display Flight Plan. Labels can be changed on options page Map Display Labels.
Hide all map features to get a clean view on flight plan related airports and navaids only. This will hide all unneeded map objects but keeps all navaids and related navaids for procedures like ILS for the approach on the map.
12.10. Airport Diagram
The display will change from a single icon to an airport diagram if you zoom in deep enough to an airport. The diagram shows all taxiways, parking positions, gates, runways and more.
The airport diagram provides more information through tooltips at the center of parking and tower positions. A right-click on a parking position opens the context menu and allows to select the start position for flight plan departure.
See Airport Diagram for details about the airport diagram.
Airport labels and diagram features can be changed on options page Map Display Labels. Disable all airport features except runways if you’d like to rely on the airport diagrams of the OpenStreetMap background map, for example.
12.11. Map Projection
The map projection can also be changed in the main menu
View -> Projection or with the toolbar button .
Note that the drop down menu of the toolbar button can be torn off by clicking on the dashed line in the menu (Tear off Dropdown Menus).
Two projections can be selected in Little Navmap:
A flat projection that gives the most fluid movement and the sharpest map when using picture tile based online maps themes like OpenStreetMap or OpenTopoMap.
Note that this projection cannot be used near the poles. Use the spherical projection if you fly in Antarctica, for example.
Shows earth as a globe which is the most natural projection. Movement can stutter slightly when using the picture tile based online maps themes like OpenStreetMap or OpenTopoMap. Use the
Atlasmap themes to prevent this.
Online maps can appear slightly blurred when using this projection. This is a result from converting the flat image tiles to the spherical display.
12.12. Map Themes
The map theme can be changed in main menu
View -> Theme or with the toolbar button which can be torn off by
clicking on the dashed line in the menu (Tear off Dropdown Menus).
This allows to change the map theme which defines the look and feel of the background map (Map Layers).
See Map Display Keys for more information on themes requiring a login or an account. Map Themes explains how to create your own themes.
Also check out the Little Navmap Support Forum at AVSIM, Little Navmap Downloads - Map Themes and LittleNavmapOFMTheme for more map themes.
