North American Overlay Mapping
Click 'Tools' > 'Pin Distance' to access this tool. Its function is to draw a line between two currently-selected Map-Pins on the current map, and show the distance between the them.
When the 'Pin Distance' tool is started, it tells you how many Map-Pins are currently selected, and which of those are on the map that you are currently viewing. If there are two pins or more, it displays a table showing the paths between them. Each path is marked with a '?' mark. To draw a line, simply click the required '?' mark.
You can also choose various options for the lines that you draw:
- Color of Lines: choice of 8 colors
- Width of Lines: choice of 3 widths
- Labels: on or off
When the line has been drawn, three additional buttons control how the graphics are displayed:
- Clear: will delete these graphics
- Hide: will hide these graphics
- Show: will show these graphics
If no lines have been drawn, these buttons will appear to do nothing, apart from giving their normal audio feedback. To turn audio feedback on or off, use the 'Options' tool.
Note: When a new map is loaded, or when you visit the Calculation Page or Table Viewer, all graphics are discarded.
