SLD Style Editor - Advanced

If you want to manually edit the SLD for the selected Layer then click on the Advanced tab.

If you manually edit the SLD via the Advanced tab and you add entries that cannot be handled by the SLD Style Editor then the Advanced tab will be your only option.

Overview

This is the actual code editing pane and shows the code for the SLD. If you wish to find a specific word in the SLD you may use Ctrl F to display a Find & Replace dialog.

Here you can manually configure the style of your OGC Layer. Astun supply some default SLD files in the folder specified in the iShare Settings General tab SldSnippetDefinitionPath. For more information on SLD please refer to the GeoServer documentation which has plenty of examples http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/index.html.

Toolbar

There is a Toolbar at the top of the Editing pane for common functions:

Undo - the last action
Redo - the last action
Cut - the selected data
Copy - the selected data to the clipboard
Paste - from the clipboard into the cursor position
Currently available snippets - allows you to insert a selected snippet at the current cursor position.
Format the SLD - clicking this button will format the SLD for you.
Import an external SLD - clicking this button will open the File Explorer for you to browse to an external SLD to load. See Using an existing SLD below.

Using an existing SLD

You may have an existing SLD that you wish to use to style your OGC Layer in iShare. If you wish to use this in iShare then you will need to do the following:

In Studio, select the Layer to which you wish to apply the SLD and click Modify Style.
Select the Advanced tab.
From iShare V5.6.30 or V5.8.2 or greater -
- Click on the Import an external SLD icon on the toolbar.
Earlier iShare versions -
- Edit the original SLD in in a text editor, such as Notepad++ - see Steps 4-7 below for Using an SLD exported from QGIS.

Prior to V5.6.0 you could only have one Rule per OGC Layer.

Using Multiple Rules

5.6.0+

If you wish to apply different styles to a Layer then you can do this using Multiple Rules.

Any field used as a SLD <PropertyName> must be made available as a Displayed Field in the Layer Fields options, and the <PropertyName> in the SLD must match the field name in the database exactly (including case).

The following SLD is an example of how we have styled the Councils layer to display different colours for different types of authority and it appears in iShare GIS like this:

Multiple Rules

<Rule>
  <Name>Unitary Authorities</Name>
  <Filter>
    <PropertyIsEqualTo>
      <PropertyName>descriptio</PropertyName>
      <Literal>Unitary Authority</Literal>
    </PropertyIsEqualTo>
  </Filter>
  <PolygonSymbolizer>

Using an SLD exported from QGIS

Step		Example
1	Open the DB Manager in QGIS, find the Layer you wish to style and select Add to canvas.
2	Now select the Layer in the Layers Panel in QGIS, right click and select Properties.
3	You will see a Style button with a drop down selection. Select Save Style > SLD File... and save it to a location of your choice. If you have iShare V5.6.30 or V5.8.2 (or greater) then you can stop here and use the Import an external SLD function in the SLD Style Editor on the Advanced tab.
4	These steps are only required if your iShare version is prior to V5.6.30 or V5.8.2. Now we need to extract the information from this SLD and paste it into the SLD Style Editor. Open the SLD in a text editor e.g. Notepad++ Now you need to remove all references to the namespace in our example below this is se:
5	Use the Replace function to replace the namespace: (in our example se:) with blank.
6	Now you need to extract just the <Rule> information. Our example above just has one Rule but yours may have several so, if you are using v5.6.0 or above, then you can extract them all. Now you can paste this information into the Advanced tab of the SLD Style Editor - replacing any existing entries.
7	Click OK to return to the Layer Save your changes.
