Map Navigator

The Map Navigator is an auxiliary window designed to facilitate orientation on a digital vector map. It displays the current digital vector map at a specified scale (independent of the current scale of the digital vector map itself). The map image scale in the navigator window can be changed by clicking the corresponding buttons. If desired, you can resize the navigator window, as well as hide or display an additional informational ruler showing the map display scale in the navigator and a panel with functional buttons.

The Navigator operates in two modes (depending on the map display scale within it).

When the scale is smaller than the original map scale — the Navigator mode is activated. In this mode, a rectangle symbolizing the location and dimensions of the map display window relative to the entire map is displayed over the map in the navigator window. You can move to any point on the map by moving the rectangle in the navigator window to the corresponding point.

When the scale is larger than the original map scale — the Magnifier mode is activated. In this mode, a crosshair symbolizing the current cursor position in the corresponding digital vector map is displayed over the moving map in the navigator window.

The navigation mode provides the ability to create and use a scenario. A scenario is a sequential set of map positions on the screen. Up to 100 points can be saved in a scenario. Comments can be added to the list row for marked points. The scenario can be saved to disk as a file with the extension *.nsc. Navigation through the scenario is performed by sequentially iterating through pre-recorded points.

The functional buttons on the Navigator control panel have the following purposes (from left to right):

• Set the composition of map objects displayed in the navigator window.

• Decrease the image scale by 2 times.

• Increase the image scale by 2 times.

• Fix the screen position (add a point to the scenario).

• Activate the first point of the scenario (the active point in the navigator window is highlighted in purple).

• Activate the previous point in the scenario.

• Activate the next point in the scenario.

• Activate the last point in the scenario.

• Move the map to the current scenario point.

• Open a scenario file.

• Save a scenario file.

• Remove the current point from the scenario.

• Remove all points from the scenario (clear the scenario).

• Activate the help system.
