High Rise Map 2D view
The High Rise Map 2D view displays for all stations the current offsets from the known position (displacements) in graphical form. For each station, it displays the reference position and, as soon as it is available, the estimated position. Error ellipses and height bars indicate the 3-s error; the difference between the estimated and the input position is shown by a solid line and height bar. A triangle indicates the station that serves as reference. A grid and a reference scale roughly visualize the scale of the map. 
How to navigate the map is described here.
Use these options and keyboard combinations to change what is displayed in the 2D map views.
Panning the view
To shift a different area of the screen to the center of the view do the following:
- Click and drag the mouse wheel (or middle mouse button).
Tip - When using a laptop without a mouse, press and hold both the left-click and right-click buttons while moving the cursor.
Zooming in
To display a smaller area of the map, in more detail, do the following:
- Click in a view, and roll the mouse wheel forward.
Zooming out
To display a larger area of the map view, in less detail, do the following:
- Click in a view, and roll the mouse wheel backwards.
Zooming into a certain area
To display the data within a box you draw in the view do the following:
- Keep [Ctrl]+[Alt] pressed, and click and drag around an area.
Zooming to the extents of your data
To zoom to the limits of your visible data do the following:
- Double-click the mouse wheel (or middle mouse button).
Changing the scale of a graphical element
To display the graphical elements representing errors and displacements in another scale than the default scale do the following:
- Right click into an empty area of the map and select the shortcut menu command Properties. Edit the scale settings.
With exception of the station marker, the color of the graphical elements does not imply the quality of the position estimation. If no data is available for a station, the circle indicating the respective station is red. Fixed stations display a blue triangle. All other station data are given in green.

Fixed station serves as reference for position differences: blue triangle with center dot.

Input (known) position of the station, not fixed.

Always displayed.

No

|
Projection into plane of the 3D displacement, that means the deviation of the adjusted position from the input position: thin solid line beginning at the station, ending with a cross.
|
Setting to toggle the display:
Show 3D displacement.
|
Yes. If the value of the 3D displacement is larger than the maximum the scale allows, the tip of the thin line gets the form of an arrow.
|
|
Adjusted height displacement: a medium, solid line beginning at a station and pointing up/down (positive/negative value).
|
Setting to toggle the display:
Show height displacement.
|
Yes. If the value of the height displacement is larger than the maximum the scale allows, the tip of the thin line gets the form of an arrow.
|
|
An error ellipse and an error height bar indicate the 3-s error in plane (2D) and height at the input position.
|
Settings to toggle the display:
Show error height; Show error ellipse.
|
Yes
|
|
A thin solid line represents the baseline between base and station.
|
Always displayed.

No

By left-clicking at any of the graphical elements you select it and can view their properties, if the Properties view is open. If you hit more than one element with the cursor, a shortcut menu appears and lets you select one of the elements.
Right-clicking into the view opens the shortcut menu with the Properties command, which opens the Properties view.
Tip - To open the Properties view with the settings of an element, first left-click the element, then right-click and select Properties from the shortcut menu.

Layers in the map
The graphical elements of the map are organized in layers. Select the map information according to your needs by toggling the display of layers.
To do so, do the following:
- Right-click into the background of any map. Make sure not to click one of the graphical elements of the map.
- Select the Properties shortcut menu command. The Properties view displays the Map2D Layer category.
- Select the setting referring to the appropriate layer and toggle its activation status: Yes enables showing the graphical elements connected with this layer, No disables their display.
Scales in the map
The map display distinguishes between baselines, stations and measurements. Error ellipse, error height, 3D displacement and height displacement are measurements. Stations are displayed with a scale-independent graphical symbol.
For measurements, the map uses a different scale than for baselines. The reason for this is that the typical measurement value ranges from sub-centimeter level up to several decimeters, while baselines may extend to tens of kilometers.
The baseline scale is displayed in the legend of the map and can be changed by zooming the map.
The measurement scale, however, is not subject to zooming, thus keeping the display of all maps in a system comparable to each other. For more information on how to influence the size of the graphical elements of the measurements click here.
To influence the screen size of the measurements in all maps in the system in one step, do the following:
- Right-click into the background of any map. Make sure not to click one of the graphical elements of the map.
- Select the Properties shortcut menu command. The Properties view displays the Measurement Scale category.
- Set Scale begins at to the smallest of measurement values you expect (default value: 0.005 m).
- Set Scale ends at to the largest of measurement values you expect (default value: 0.3 m).
The map then displays measurements below the start value of the scale with the smallest possible drawing size and displays measurements above the end value of the scale with the largest possible drawing size.
Note - If the value of the 3D displacement exceeds the scale, an arrow appears at its tip instead of the usual cross.
In between the maximum and minimum of the scale, the map scales the graphical elements of the measurements according to their values. Effectively, with these two settings you set the focus to the range of values you want to observe and compare.
In order to keep all map displays comparable to each other, the smallest and largest possible drawing size on the screen are determined by the system and cannot be changed. The possible drawing sizes depend, for example, on the screen resolution.
