Composition studio
1. Application description
The application presented in this document is used to create map compositions, which can then be shared with external users for data presentation or analysis.
Map Composition Studio does not require installation or configuration – it opens directly in a web browser window (and does not require installing additional plugins). Its primary function is the process of creating a map composition.
Figure 1. Map Composition Studio
The Map Composition Studio is an intuitive wizard that allows the user to prepare a map composition based on available resources and functions, as well as save and publish it.

3. Application control
The main device for operating the application is a computer mouse. It allows for basic map navigation, configuration of subsequent elements, and operation of application functions.
Controls are intuitive and straightforward. All functions are activated by hovering the mouse cursor over the appropriate icon and then pressing the LPM (left mouse button-LMB).
Moving around the map: the user holds down the LPM (left mouse buton-LMB), drags the map to the desired location, and then releases the button.
The user can also uses the arrow keys on keyboard.
Zooming in/out the map: The user uses the mouse wheel to scroll up or down.
Entering a value: The user highlights the appropriate field, LPM click (left mouse button-LMB), and enter the value using the keyboard.
4. Application features
This section describes the individual features of the Map Composition Studio, which are available to logged-in users.
5. Launch of the Map Composition Studio
The Map Theme Studio is launched from the Resource Manager. The user selects the Add Resource + → Service → from the drop-down list New map composition.

6. Map Contents
In the “Map Contents” tab, the user selects the data that will be included in the composition from a list.
A map is selected by LMB -click (left mouse button-LMB) on its name. The selected map is marked in color.
The user can select multiple background maps.
Add data
To add a new resource – data, the user selects the “Add Data” button.
A window appears, allowing to search for data and add it to the application.
Figure 3. Map Contents - Add Data
The user can select a resource directly from the list or search for it using the available filters:
Searching for a resource by name,
Filtering by resource type selected from the list,
Filtering by availability of a resource selected from the list,
Filtering by keywords of a resource selected from the list,
Filtering by resource characteristics (name, ID, creation date, modification date),
Sorting resources in ascending or descending order,
Filtering resources marked as favorites.
The user selects a resource by clicking **LPM**(left mouse button-LMB) on its name and then the Select and go to configuration button.
Figure 4. Add data - Data Selection
The specified resource is added to the application. The user can add more than one data resource at a time.
Figure 5. User data - Added Data
The “Menu” button next to the layer provides a context menu with the Duplicate and Delete options.
The duplicate layer has the same configuration parameters as the source layer.
Add Group
The user selects the Add Group button. The tool widget is displayed.
Figure 6. User Data – Add Group
The user enters a name for the group and selects the Save button. The group is added and displayed in bold text on the layer list. To add layers to the group, the user drags and drops the visible layers from the list.
Add Layer to Group
Figure 7. Add Layer to Group
Load Composition Definition
This function allows the user to load a predefined definition for a map composition from disk.
Figure 8. Load the composition definition
Edit Composition
This function allows the user to add their own rules to the code that define the composition.
Figure 9. Edit Composition
Layer Settings
The user selects a layer from the user data list (the layer gets highlighted),
and then chooses the Layer Settings button from the right-hand menu.
Here, information about the data source and basic layer configuration parameters can be found, e.g., the layer name.
Figure 10. User Data – Layer Settings
Using checkboxes, the user decides whether the layer should be visible in the Layer List and uses the available layer options.
With the slider, the user changes the layer’s opacity percentage.
Symbolization
The user selects the Symbolization button. Tools enabling layer symbolization are displayed.
Additionally, at this point the user sets the layer’s scale range using a slider, or by typing or selecting a scale value from the list.
The scale settings apply to the EPSG:2180 coordinate system.
Figure 11. Layer Scale Range Configuration
The list of available options for Presentation Type depends on the layer’s geometry type.
The options from the list define the available symbol parameters for configuration.
In most cases, the symbol is complex and presented as an expandable tree.
Each tree element may also have different parameters to configure.
Figure 12. Symbolization Example for Point Geometry
At the main tree element level, the user can: - select a symbol from the symbol catalog, - configure scale dependency, - enable clustering and cluster labels.
Figure 13. Symbolization Example for a Simple Marker
For the next tree element, Simple Marker, different parameters are available, such as: marker type, symbol, fill, stroke, size, offset, and rotation. Creating complex symbols (multisymbols) is possible using the right-hand panel next to the tree.
Figure 14. Multisymbol Management
The presentation type changes depending on the layer’s geometry type.

The User selects a layer and activates the toggle. The system displays the parameters for configuration.
Figure 30 Labeling parameters
It is possible to create label classes using { +} and symbolize each class differently.
The {Expression} tab:
Label field – attribute to display as labels
Condition – only objects that meet the condition
Figure 31 Labeling – condition
Advanced Expression
The User can construct an advanced expression by activating the ( ) toggle. The system displays a form for building advanced expressions.
The User uses the field search and logical operators to create an expression according to which labels will be displayed.
To include a specific field in the expression, it can be entered in the appropriate format.
Figure 32 Labeling – advanced expression
In the {Text} tab, the User configures parameters related to the appearance of labels:
Font – Open Sans, Roboto, or Fira Sans
Size
Text color and opacity
Bold and Italic
Rotation
X and Y offset
Outline thickness, color, and opacity
Figure 33 Labeling – text
In the {Position} tab, the User can set the position relative to the point: top, top-left, top-right, bottom, bottom-left, bottom-right, centered on the point, left, or right. The configuration is done by selecting a value from the list. For polygons, there is only one option: horizontally inside the polygon. Similarly, for lines, the only option is: centered along the line. Additionally, the Label conflict resolution option, which is enabled by default, prevents label overlapping.
Figure 34 Labeling – position
In the {Visibility} tab, the User sets the display range of labels by entering minimum and maximum scales, selecting a scale from the list, or using sliders.
