Feature Description

Chart symbology is one of the core features in SuperMap chart browsing. By configuring nautical chart properties parameters, you can control chart symbology styles, color modes, symbols, and boundary types to achieve precise display effects adapted to various scenarios. These settings enhance chart readability and navigation accuracy.

Steps

1. Load the chart group to be viewed into the map.
2. Select the Chart Tab -> Nautical Chart Properties group -> Click the Nautical Chart Properties button. The Nautical Chart Properties panel will appear on the right. Expand the Show Settings group.
3. The Show Settings group contains the following options:

• Display Category: Choose appropriate display methods for different application scenarios to optimize chart data presentation.
  • Chart Symbology: Displays charts according to S-52 electronic chart standards, ensuring industry-compliant symbols.
  • NONE: Displays map data as basic points/lines/areas without symbology. This mode improves display performance during chart data editing and reduces symbology interference.

• Scale Zoom:

  • Edit Scale: The edit scale in chart group properties indicates the minimum display scale in maps. Right-click a chart group in Workspace Manager -> Select Properties -> View Edit Scale in the right panel.

  • Scale Zoom: Controls chart data visibility at different display scales. Example: If a chart group's edit scale is 1:80,000 with zoom factor 0.05, data auto-hides when map scale exceeds 1:1,600,000. Enable "Display Chart Frame" to view data range, or set zoom factor to 0 for persistent display.
