Rotating layered symbols in a chart (Maritime Charting)
The symbology that results from an automated process is a starting point for chart creation. Cartographers usually need to edit the resulting symbols and annotation to remove overprinting and improve the clarity and legibility of the chart. Edits made to representations do not affect the underlying geometry when using the Nautical symbology configured for paper chart products that are provided with ArcGIS for Maritime: Charting.
Some lights may have more than one representation rule. For example, a light can have a rule for a star and a rule for a light flare. To rotate just one symbol, such as the flare, and leave the star upright, perform the following steps.
- Start ArcMap.
- Open the product map document.
- If necessary, add the Nautical Editing Cartography toolbar from the main menu by clicking Customize → Production → Toolbar Settings → Nautical Chart Production.
- Select one or more lights for which you want to rotate the flare.
- Click the Rotate tool on the Nautical Editing Cartography toolbar.
- If necessary, click the Representation Properties button on the Nautical Editing Cartography toolbar.
The representation rule is made up of two markers: the star and the flare. The star is the bottom, or first symbol, and the top, or second symbol, is the flare.
- Click the Tools tab.
- Uncheck the Angle check box for Layer 0.
This is the star layer; leave the Angle check box for Layer 1 checked.
- Click the Drawing tab.
- Drag the mouse pointer around to visually rotate the lights so that only the flare will move.
If you click other lights with the same representation rule while in the same ArcMap session, Layer 0 will remain unchecked for rotation.
