== 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:

This page describes how to create a Maria GDK map client utilising MariaGlobeMapControl with 2D and 3D visualisation of map, tracks and draw objects.

Maria Globe Client

General

This page is under construction!
Note
  • You will need to include the TPG.Maria.MariaGlobeMapControl NuGet package (Currently available Teleplan Globe internal only)
  • 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
