The purpose of this map is to highlight river annotations. Since the length of major rivers is often long, cyclic labeling is required.

Operation Steps

1. In the Layer Manager, right-click the MainRiver_L dataset, and select Create Thematic Map ... from the context menu.
2. In the pop-up Create Thematic Map dialog, select Single Symbol Label Thematic Map to generate a default style label thematic map.
3. In the Thematic Map window's Properties tab, configure the following settings:

   Parameter	Value
   Label expression	Name
   Offset unit	0.1mm
   Offset X	-40

4. In the Thematic Map window's Style tab, configure the following settings:

   Parameter	Value
   Font	SimSun
   Font size	15
   Tilt angle	40
   Text color	RGB(0,113,255)
   Font effect	Italic, Outline, Fixed size

   Use default values for other parameters.
5. In the Thematic Map window's Advanced tab, configure the following settings:

   Parameter	Value
   Fixed text angle	Checked
   Along-line display direction	Top to bottom, Left to right
   Along-line character spacing	8
   Along-line periodic spacing	2500

   Along-line character spacing represents the distance between characters in the label text, in multiples of character height. The value range is 1-8, indicating the distance is 1-8 times the character height. Here, set the along-line character spacing to 8, meaning the interval between texts is 8 times the character height. Along-line periodic spacing of 2500 means the distance from the start (end) of one label text to the start (end) of the next label text is 2500 map units. Use default values for other parameters. For detailed descriptions of the "Advanced" tab parameters in the Uniform Label Thematic Map, refer to Label Thematic Map "Advanced" Tab.
6. Modify the display style of MainRiver_L. In the Layer Manager, select the MainRiver_L layer, right-click, and choose "Layer Style" from the context menu. In the "Line Symbol Selector" window, set the line type to default, line width to 0.1mm, and line color to RGB(115,178,255).
7. For better map display effects, in the "Map Properties" interface under "Basic" parameters, check "Line Antialiasing" and "Text Antialiasing".
8. After setup, save the map, with the map name as River Label Alongline.
