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.

Best Practice

Use a WHERE clause in the SQL statement for your Layer to limit the features being displayed rather than using FILTER statements in the SLD styling. Only use FILTER statements to style the display of the visible features.

Using Multiple Rules

5.6.0+

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

For a list of available filter functions that can be used with in a Rule/Filter see: https://mapserver.org/ogc/filter_encoding.html

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:
