== Advanced map settings ==
=== Map rotation ===
As default, 2D maps are displayed with north up, but you may rotate the map by modifying the map layer rotation parameter - GeoContext.RotateValue.
Add the following components:
* Text box to display the current rotation value
* Two buttons, for right (clockwise) add left (counter clockwise).
Add the following to your Main Window XAML:
<source lang="xml">
. . .
<Label Grid.Row="4" Grid.Column="0"
      Content="Rotation" FontWeight="DemiBold"/>
<TextBox Grid.Row="4" Grid.Column="1" Margin="3"
        Text="{Binding MapViewModel.Rotation}" TextAlignment="Right" />
<StackPanel  Grid.Row="5" Grid.Column="1" Orientation="Horizontal"
            VerticalAlignment="Center" HorizontalAlignment="Center">
    <RepeatButton Margin="3" Width="50"
                  Content="Left"
                  Command="{Binding MapViewModel.RotateLeftCmnd}"/>
    <RepeatButton Margin="3" Width="50"
                  Content="Right"
                  Command="{Binding MapViewModel.RotateRightCmnd}"/>
</StackPanel>
. . .
</source>
And implement corresponding properties and command handlers in '''''MapViewModel''''':
<source source lang="C#">
. . .
public ICommand RotateLeftCmnd { get { return new DelegateCommand(OnRotateLeft); } }
public ICommand RotateRightCmnd { get { return new DelegateCommand(OnRotateRight); } }
private void OnRotateLeft(object obj)
{
    Rotation += 1;
}
private void OnRotateRight(object obj)
{
    Rotation -= 1;
}
public int Rotation
{
    get { return _mapLayer.GeoContext != null ? (int)_mapLayer.GeoContext.RotateValue : 0; }
    set
    {               
        _mapLayer.GeoContext.RotateValue = value;
        NotifyPropertyChanged(() => Rotation);
    }
}
. . .
</source>
Pressing the buttons, the map is rotated, and the rotation display is updated accordingly.

=== 3D map settings ===
==== 3D Properties ====
The '''''Globe Client''''' 3D view is the view from a camera towards a target, specified by the following parameters:
{| class="wikitable"
|-
!  !! Description !! 
|-
! scope="row" style="text-align:left;" | Camera yaw
| Horizontal rotation, degrees - counterclockwise.
|rowspan="3" | [[File:Roll_pitch_yaw_2.png|150px|Roll, pitch and yaw ]]
|-
! scope="row" style="text-align:left;" | Camera pitch
| Front/back rotation, degrees - counterclockwise
|-
! scope="row" style="text-align:left;" | Camera roll
| Left/right rotation, degrees - counterclockwise.
|-
! scope="row" style="text-align:left;" | Follow ground
| colspan="2" |
Lock the target altitude is to the elevation of the target position.
|-
! scope="row" style="text-align:left;" | Target altitude
| colspan="2" |
Height above sea level (0-elevation)  at target position.
Changes are not applicable while:
* auto follow is active, as the target elevation is defined by the item followed.
* follow ground is active.
|-
! scope="row" style="text-align:left;" | Target position
| colspan="2" |
Latitude and longitude. Changes are not applicable while:
* auto follow is active, as the target position is defined by the item followed.
|-
! scope="row" style="text-align:left;" | Target distance
| colspan="2" | Distance from camera to target.
|}
;Note
:* 3D rotations are ''not commutative''.
:: Performing the same rotations in different order will give different results.
==== Implementation ====
To visualise how these parameters are connected, add the following elements to your main window:

Maria Globe Client

These pages describe how to create a Maria GDK map client utilising MariaGlobeMapControl with 2D and 3D visualisation of map, tracks and draw objects.

General

Note
  • You will need to include the TPG.MariaGDK3D NuGet package. (Currently available Teleplan Globe internal only)
For more info, see Loading Maria GDK, NuGet Packages
  • Sample code is found in the MariaGlobeClient project, in the Sample Projects solution.
  • Note that the sample code is specifying the service connections in code, and not by app.config.
  • For general troubleshooting, see Development troubleshooting

Sections

The following main topics are handled
1. Utilising the globe control

2. Map interaction

Map Pref 3D.PNG

3. Draw object interaction

DrawObjects 3D.PNG

4. Track interaction
