Need to add images

To have these views working correctly, you need to have events related to places. These places must have coordinates : latitude and longitude.

If one place has no coordinates, we'll never see it on the map.

here are different ways to add coordinates to places :

1. Within the menu popup you can link or add one place.
2. ...

If you have internet active, for all moves on the map, all zoom ... all tiles are saved. When you are without internet, all tiles cached in a previous session can be used. So, the map can be used without internet.

The only thing to do is for each place or area you want to use without an internet connection is to select them, zoom into these places. You'll be able to use them again without connection.

BE CAREFUL : it can takes gigabytes. If you use several maps, you need to have this same gigabytes size multiply by the number of map used.

The different views

All known places for one person

This view show all places visited by one person during his life.

This view is not connected to filters. It only depend on the active person and the history.

In the menu popup, you can select 'animate' to see the life way of the current person :

If the active person has several related events, you can see a virtual move between those markers. The move is related to years or distance and can be modified in the person map preferences. If the distance between to markers is greater than a value in tenth of degree, we show moves depending on distance instead of years. In these case, the number of steps between these two markers can be modified. You can modify the animation speed between steps. The moves start at the first event year until the last event year.

In the configuration menu, you can set the following :

1. The animation speed in milliseconds.
2. How many steps betwwen two markers for long moves.
3. The minimum latitude/longitude to select large move. This value is in tenth of degree.

This view show all places visited by all family's members during their life.

This view is not connected to filters. It only depend on the active family and the history.

Usage

The configuration

All views

See the description of the view.

The mouse actions on the map

button 1 ( left button )

You have two usages for the button 1 :

1. The marker selection.
2. Valid the region selection

The mouse over a marker

When the mouse is placed over one marker, we display the place name in the status bar.

The menu popup

From this menu, you have the following functions available for views :

1. hide or show the crosshair
2. lock the zoom : force to no center and no autozoom. Useful when we want to see a selected area of the map.
3. change the default map
4. add a place and link a place at the mouse position
5. center the map at the mouse position.
6. change the map provider

Click on a marker

We have two cases :

1. events : For each event, we can edit this event or center the map on this place.
2. places : For each place, we can edit this place or center the map on this place.

When centering the map, the zoom used is defined in the geography preferences.

We may have several markers in the click area depending on the zoom. In this case, We show for each marker all related events and/or places. We obtain a mix between the two cases described above.

Adding or Linking to a place

When you add a place or try to link a place to the position of the mouse, you'll get a place selection in a region. You'll see on the map a circle in which you may choose markers place names. You can adjust the circle size with the cursor. Depending on the diameter of this circle, a list is created. If the place has already some filled fields, you'll see these values in a green color row. If you agree, you double click on this row. if you don't agree, you can choose another row.
