Spatial rainfall can be viewed on the
GeoPlan by enabling the display of radar cell boundaries and making use of a Rainfall theme.
You can
save the current themes and view the properties of current themes on the
Layer Theme Editor
or the
Thematic Key Window
.
To display the spatial rain:
- Open the desired
network in the GeoPlan.
- Associate the
spatial time series data object, containing the spatial rain of interest to the network currently displayed on the GeoPlan, by dragging and dropping the spatial TSD object from the
Explorer window onto the GeoPlan. The name of the spatial TSD is appended to the GeoPlan titlebar and the
Time Series Data Grid is displayed. Leave the TSD grid open.
- Right-click on the GeoPlan and choose Properties & themes from the popup menu. This displays the
GeoPlan Properties dialog.
- Click Edit in the Theme column for the Rainfall object layer. The
Layer Theme Editor is displayed:
- The default rainfall theme is called Rainfall Intensity. It is based on rain intensity and the default Map Type is Filled but other types are also available (see table below). Fill contours of rain intensity values have been auto-themed so the Draw Style Preview displays a set of colours as shown in the image above.
- You can use the default parameters or set up your own as required and click OK to commit your changes. See the Rainfall Theme Data Fields table below.
- Turn on the theme display by checking the Display check box for the Rainfall object layer in the Layers and Themes tab of the GeoPlan Properties dialog.
- It is also possible to turn on radar cell boundaries and status bar values. This step is entirely optional and instructions on how to achieve this are given below:
- Switch to the
Visual Page.
- Check the Show radar cell boundaries box to display radar cell boundaries on the GeoPlan.
- If required, also check the
box to display the following information on the
Status Bar:
- ground level (a
Ground Model must be loaded in the GeoPlan)
- spatial rain (when a
Spatial Time Series Data object is loaded in the GeoPlan) on the
Status Bar.
- Click Apply and OK on the GeoPlan Properties dialog (It is also possible to save these settings by using the Save button. See
Network editing properties - save options dialog topic for more information on the available saving options).
- Select different rows in the Time Series Data grid and observe the colour changes in the Rainfall theme on the GeoPlan.

Map Type
|
The table below contains the available map types for rainfall themes:
Option
|
Description
|
Filled
|
Rainfall Thematic displayed as filled contours. GIS layers will be obscured.
|
Show Layers
|
Displays GIS layers on top of Rainfall. Thematic displayed as filled contours.
|
Transparent
|
Rainfall Thematic is displayed as transparent filled contours allowing GIS layers to be seen.
|
|
Range Settings
|
The only available option is Continuous. This will display the Rainfall based on a series of ranges of intensity.
Option
|
Description
|
Use AutoRange
|
Automatically re-scales values if a different network or simulation is opened.
|
Relative Palette
|
InfoAsset Manager will apply the selected set of colours in the Fill Colour column of the Ranged Themes grid to the part of the Rainfall currently being viewed on the GeoPlan. Values are automatically re-scaled when the GeoPlan zoom is changed.
|
|
Visibility Range
|
The Min and Max boxes determine the map scale/zoom level at which the rainfall is visible.
|
Ranged Themes grid
|
Please refer to the
Layer Theme Editor topic for details on how to set up themes using the controls in this grid.
Two important points:
- The more ranges that are selected, the smoother the colour effect will be when using filled contours.
- InfoAsset Manager can interpolate between the colours of the first and last rows of the Fill Colour to create a graduated set of colours.
