Navigation map
The Navigation Map window provides quick and easy navigation through the entire terrain. It shows a raster-based map and the location and direction of the camera view on the map. The Navigation Map window offers a simple mechanism to integrate file or server-based maps into the application.
The Navigation Map supports the same file formats and servers as are supported for raster layers. See "Loading Raster Layers" in the "Imagery and Elevation Layers" chapter for information.

The Navigation Map Window
Current Location Indicator
The Navigation Map marks the camera’s location and field of view. The indicator shows the direction of the flight in the 3D Window as a red plane icon, and the direction and field of the camera’s view as two blue lines.

Location Indicator
By default, the indicator is in the center of the Navigation Map. If the cursor is located near the edge of the map, the location indicator may be off the center.
If the cursor is currently located outside the area of the map, the location indicator is not present.
Using the Navigation Map
If the Navigation Map is not displayed, on the View tab, in the Show/Hide group, select the Navigation Map check box.
Selecting a navigation map
The Navigation Map window can contain more than one map for the same project. At the top of the Map Window, select the required Navigation Map from the dropdown list of available maps.

Select Map
Moving to any location on the terrain
Using a Navigation Map, you can jump directly to any place on the terrain.
To move to any location on the terrain, do either of the following:
§ Double-click on any area of the navigation map to jump directly to the chosen location.
or
§ Right-click on the required spot on the map, and select Jump from the shortcut menu.
The view in the 3D Window is synchronized with the plane indicator position on the navigation map.
To turn-off synchronization:
§ Right-click the map area, and toggle off the Synchronize 3D option.

3. Browse to the required map and click Open.
Note: The Navigation Map supports the same file formats and servers as are supported for raster layers. See "Loading Raster Layers" in the "Imagery and Elevation Layers" chapter for information. It is strongly recommended to use a compressed format (JPEG or GIF) and not BMP, for Navigation Maps. This ensures maximum performance with slower Internet connections.
4. In the Navigation Map Settings dialog, define the property sheet parameters as required.
5. If the map is not referenced to the coordinate system of the terrain, do either of the following:
§ Reprojection - When the map is referenced to a different coordinate system than the coordinate system of the terrain. See "Reprojecting a Navigation Map" in this chapter for further information.
§ Manual Adjustment - When the map is not referenced to any coordinate system. See "Adjusting a Navigation Map Manually" in this chapter for further information.
Reprojecting a navigation map
When the navigation map is referenced to a coordinate system, which is different from the terrain coordinate system, the map must be reprojected.
To reproject a map:
1. On the Navigation tab, in the Map group, click Map. The Navigation Map Settings dialog is displayed.
2. In the Maps section, select the required map.
3. In the Projection section of the property sheet, in the Reproject Source, select Yes to enable reprojection of the source.
4. In the Coordinate System field, click Set. The Coordinate System dialog opens. Enter the source file’s coordinate system information. See "Coordinate System Dialog" in the "Basic Concepts" chapter for information.
5. Click OK.
Adjusting a navigation map manually
Adjusting a navigation map manually is required when the navigation map is not referenced to any coordinate system. The manual adjustment is performed by pairing map locations with their terrain counterparts.
To manually adjust a navigation map, do the following:
1. On the Navigation tab, in the Map group, click Map. The Navigation Map Settings dialog is displayed.
2. In the Maps section, select the required map.
3. In the Imagery section of the property sheet, in the Manual Adjustment field, click Set. The Navigation Map Settings dialog is minimized.

Multiple coordinate systems
The Multiple Coordinate Systems tool projects the current position into multiple coordinate systems simultaneously. A display mode selector at the top of the dialog controls which position is tracked across all panels: Camera Location, Cursor Location, or Screen Center. The dialog includes Lat Long and MGRS sections, which are always included, plus an additional section where you can select another coordinate system to project the current coordinates into. You can also type a coordinate in any of the available coordinate systems to jump to that location and use the built-in Coordinate Converter to reproject between any two coordinate systems, independently of the current position in the 3D Window.

Multiple Coordinate Systems Tool
To use the Multiple Coordinate Systems tool:
1. On the Navigation tab, in the Navigation Aid group, click Multiple Coord Sys. The Multiple Coordinate Systems dialog opens.
2. Select which position to display across the dialog's coordinate system sections:
§ Camera Location - Current camera (viewpoint) position
§ Cursor Location - Position under the mouse cursor on the terrain
§ Screen Center - Position at the center of the 3D window
3. In any section (Lat Long, MGRS or a custom coordinate system), do the following:
a. To copy the coordinates of the current position, click Copy.
b. To jump to a specific location, type the location's coordinate values and click Set. The camera's landing point depends on the active display mode:
§ Camera Location mode - Jumps directly to the typed coordinate, preserving the current yaw and pitch.
§ Cursor Location or Screen Center mode – Positions the view above and behind the point so it appears at the center of the screen.
Note: The Lon/Lat input fields support multiple coordinate formats
§ Decimal degrees – 34.5 or 34.5°
§ Degrees, decimal minutes – -81° 0.001′
§ Degrees, minutes, seconds – 28° 32′ 4.604″
§ Values can be entered with N/S/E/W prefixes or suffixes
4. To add another coordinate system, in one of the Not Assigned sections, click Choose Coordinate System. The Coordinate System dialog is displayed. Enter the required information. See "Coordinate System Dialog" in the "Basic Concepts" chapter for information.
5. To reproject coordinates between any two coordinate systems, independently of the current position in the 3D Window, expand the Coordinate Converter section at the bottom of the dialog and do the following:
a. In From, the project's current coordinate system is pre-populated. To change it, clickChoose CS to select a different coordinate system, or click MGRS to use MGRS. See "Coordinate System Dialog" in the "Basic Concepts" chapter for information.
b. In To, click Choose CS to select the target coordinate system, or click MGRS to use MGRS.
c. Enter the coordinate values in the input fields. The fields adapt to the selected coordinate system: Lon/Lat for geographic systems, X/Y for projected systems, or a single text field for MGRS. Entering an altitude in Alt (AMSL) is optional and defaults to 0.
d. Click Convert. The reprojected result appears below the Convert button. If any fields contain invalid values, they flash red.
GPS tracking
The GPS Tracking tool creates 2D or 3D objects and moves them according to position information, in NMEA format that it reads directly from a GPS or communication device through a USB or COM port or from a local or remote file. The GPS tool supports multiple entities in a single device and allows fast forwarding capabilities when reading the information from files.
You can display the GPS-moving objects in a variety of 2D or 3D graphic representations and add trace lines trailing the object routes.
