The Map screen displays observation and forecast information in overlay and widget format on a Google Map. The default map display is shown below:

View Mode

The view mode controls the amount of geographical labeling present on the map. The map will load in a simple view by default. The view can be switched to a detailed mode to show place name information.

Examples of a simple and detailed view of New Zealand are shown below:

Slider Playback

Where an overlay returns a series of images across a time period, a slider will appear at the bottom of the map:

The slider controls behave as follows:

Play the overlay images.
Play the overlay images in a loop.
Alter the speed at which the overlay images are played.
Change the image resolution.
Change the static overlay image to a different time of day.
Indicates the time for the currently displayed overlay image. When the images are playing the yellow marker will move appropriately. The yellow marker can also be manually dragged up and down the slider to alter the visible overlay image.


Weather Stations

Weather stations provide observation information for a specific location. The weather station widgets available display these observations and forecast information from weather models. There are currently three weather station settings for the Map, as shown below:



Overnight Minimum

Different weather stations will be visible at different zoom levels, to prevent clutter in the display onscreen. The NZ Map display includes only main centres or weather stations that are considered important to the organisation of the logged in user. As the Map is zoomed to a particular region or location more weather stations appear.

Weather Observation Widget

Displays observation data at a given location. These widgets appear as follows:

Hover over the widget for information about the location of the weather station and the time at which the last observation data was received.

The information contained in the widget is explained below:

A black compass is placed over the location at which observations are collected. This compass includes wind information including:

  • Wind Speed in kilometres per hour - the top number, i.e. 22, a ten minute mean
  • Wind Gust in kilometres per hour - the bottom number, i.e. 30, the maximum gust for the last ten minutes
  • Wind Direction - the arrow on the compass indicates the direction that the wind is going, i.e. from South to North
The air temperature value in degrees Celsius

The intensity of the rain over the last 10 minutes

  • No reading or zero rain - left as blank
  • 0.2mm = L for light
  • 0.3mm - 0.9mm = M for moderate
  • 1.0mm - 2.4mm = H for heavy
  • 2.5mm and above = T for torrential
