Areas in QMapShack

Areas in QMapShack

An area in QMS can be used to define a region on a map in which, for instance, a search and rescue operation should take place or where access is prohibited (a so-called no-go area as shown with area1 in the following image).

Of course, you can try to play Tetris with area overlays, too.

Areas are multi-point data items and share the common features of such data.

Create area

The creation of a new area is similar to the creation of a track or a route and is described here. The essential difference is that the last point created and the first one are joined by a line segment to get a closed line as border of the area.

The previous image shows some areas created without using a routing engine (toolbar option O). Here, the border of the area consists of straight line segments joining the clicked points. The following image was obtained using a routing engine (toolbar option A). The clicked points are joined by road segments found by the router (the meaning of the various black points on the area border is explained here.

Area info window

Edit the area name. Simply click on the highlighted name to edit it.
This icon is a warning that the data item is not created in QMS but loaded from some file and then edited. Saving such data back to a file may lead to a loss of some detailed information because not all file types support saving of all information handled by QMS. If the area was created in QMS, then this icon isn't shown.
GIS items are locked, when imported into QMapShack. If the lock is closed, data editing is not possible. Press the lock icon to unlock (or lock) data for editing.
Select the color of the area.
Select the border width of the area.
Select the fill pattern of the area. Solid or no pattern can be found next to the criss-cross patterns.
Set the area to opaque.
The 3 tabs Info, Points, Hist. provide
1. a description, a comment and links relevant for the area (click on the highlighted strings to edit them, for details see here),
2. a read-only list of all points used to create the area (for editing these points, click the Edit shape... icon, for details see here),
