How to Generate Texts in the SPRING

For the thematic model it is possible to generate themes associated with polygons, lines and points.

For the cadastral model and networks it is possible to generate texts for objects associated to the information layer.

For the numerical model it is possible to generate texts for samples in general, either points or height lines.

First select the IL, in the Control Panel, where the text will be generated, because the text will be generated in the active IL.


Generating text for a Numerical model IL:

  • Selection:
    • Select Selected Classes to generate the text only for the classes previously selected for visualization in the Control Panel.
    • Select Selected Points to generate the text for the point classes chosen by clicking with the mouse on the display.
    • Select Selected Lines to generate the text for the line classes chosen by clicking with the mouse on the display.
    • Select Selected Polygons to generate the text for the polygon classes chosen by clicking with the mouse on the display.
    • Select All to generate the text for all the entity classes of the information layer.  
  • Defining the Visual aspects: When clicking the Visual... button the Settings for Text Visualization window will be presented with some standard values, just change some of these values, usually color, thickness, font style and spacing, and the angle will be computed by the algorithm, then click in Apply in the Text Visualization window to finish the definition.
  • Add to IL: Used when the text representation already exists in the active IL and one whishes to add a new text to the same IL.
  • Another field to be defined is the horizontal displacement in the View Control. This value is used as a displacement between the lines and/or points and the text to be inserted.
  • click on Apply.

 

NOTE 1: The selected entities (points, lines or polygons) are presented in CYAN color.

NOTE 2: To deselect an entity (point, line or polygon), just click on it.

NOTE 3: Only the classified entities (points, lines or polygons) can be selected.


Generating text for a Numerical model IL:

  • For points and index contours: The text will be generated only for points and index contours in the active IL.
    • Changing index contour:
      • A value (in meters) for the initial contour line has to be provided, such that the masters will be designated.
      • Give the interval between the index contours; for instance, if the data corresponds to heights between 0 and 1000 meters, then, it is possible to define, as an initial contour line, the value 0 and as interval the value 100. In this case 10 index contours will be defined.
    • Defining the Distance between texts (meters): The value between two texts in the same contour line.
    • Defining the number (#) of decimal places in the text. It varies from 0 to 6. This option is only valid for the DTM.
    • Defining the Visual aspects: When clicking the Visual... button the Settings for Text Visualization window will be presented with some standard values, just change some of these values, usually color, thickness and spacing, and the angle will be computed by the algorithm, then click in Apply in the Text Visualization window to finish the definition.
    • Another field to be defined is the horizontal displacement in the View Control. This value is used as a displacement between the 3D point and the text to be inserted.
  • For points and contour lines: Texts will be generated for all contour lines and points from the active IL.
    • In this case it is still required to define the distance between the texts, the visual aspects and horizontal displacement between text and points, as described above.
  • click on Apply. The text will be generated and next it will be presented in the SPRING active screen.

Generating text for a Cadastral model or Network IL :

  • Selection:
    • Press the Category button to select a category of the object model;
    • Once the category is selected, the Attributes list of the selected category will be filled, and the LABEL, NAME and GEOID. Select the desired attribute.
  • Defining the Visual Aspects: When clicking on the Visual button the Settings for Text Visualization window will be presented with some standard values, just change some of these values, usually color, thickness, font style and spacing, and the angle will be computed by the algorithm, then click on Apply in the Text Visualization window to finish the definition.
  • Add to the Infolayer: This is used when a text representation is already presented in the active IL and a new text has to be inserted in the same IL.
  • Alignment: It is possible to define the following alignments:
    • Horizontal:
      • LEFT
      • CENTER
      • RIGHT
    • Vertical:
      • TOP
      • HALF
      • BOTTOM

  • Another field that has to be defined is the horizontal displacement in the visualization control. This value is used as a displacement between a point or line and the text to be inserted.
  • click on Apply. The text will be generated and next it will be visualized in the SPRING active window.

IMPORTANT:

While the user remains working in the text generation module the Control Panel will be disable to events from the categories list; it is only allowed to navigate through the information layers list.

Be careful, because, the text will be generated for the active IL during the execution time.

It is not recommended to change the IL while the process is not completed, unless the user really knows what he/she is doing.

If the user wants to manipulate the IL, he/she should close the text generation window, mainly if he/she wants to change the category.

Note: As this is an automatic process, it is likely that it will need some adjusts, which can be done in the Text Editing module.
