Help version 1

Basic usage

1. Current overlay

You can see the currently displayed overlay and its date/time in the top-bar. By default the time is selected as the closest to the current time. You can switch the shown time with the slider. Actual measurements are shown for timestamps before the current time and forecasts for the future times.

2. Overlay selection

Overlay can be switched from the menu in the right. Current options are Air Quality Index, Light/Medium/Heavy Rain.

3. Location based centering

Map can be centered to current location by pressing the location button. Please note that browser should be given the permission to provide location info to this site.

4. Map controls

Default map controls are in use and you can zoom in/out of the map as well as drag to change the location shown.

Notifications

1. Setting the notification

Notications tell with a system popup if the value of the selected measurement goes to the selected value range or over it. To set a notification you will need to zoom in the map at least until the buildings are visibile. After that you can click the map to see the development of the measurement within time as per the example. After that it is possible to select the wanted threshold you want to have the notification for. (For example AQI 1-5 for the Air Quality Index.) After pressing notify me the location is shown as a red marker in the map and the notification setting is valid. You can set one notification for each of the measurement types. If you set an another one for a measurement which already has one, then the previous will not be in effect anymore. Please make sure the browser you are using has notifications allowed for the cityzerdemo.fmi.fi site, otherwise the notification marker is not stored.

1. Currently selected notification location

Currently active notification location is shown in the map as a red marker. If you want to remove the notification marker for the selected measurement, you can click anywhere in the map and select 'Don't notify' in the opened popup.
