Update .MAP file for Elgin Roadworks

This example assumes that the Elgin data is in PostgreSQL, with the connection information in an include file called datashare.inc. This is not entirely standard, but the important part here is the DATA string.

In this example we have included three different layer snippets for:

• Delays possible
• Delays unlikely
• Delays likely

This example assumes that there are the following three manatw symbols "mat at work" in the MapServer symbols file: 

Image	Image Name	Snippet for .sym file	Image	Image Name	Snippet for .sym file
	manatw-B.png			roadworks.png
	manatw-G.png			roadworks_yellow.png
	manatw-F.png			roadworks_orange.png

We have also included some others if you should wish to use them. To configure iShare to use the attached symbols then you will need to:

• Save the image(s) to your E:\iShareData\LIVE\_MapServerConfig\CustomSymbols\mapicons\images folder.
• Add a link to these icons, using the above snippets, in your mapicon_abc.sym file (in the mapicons folder) where abc is what you have called your cut down copy of the mapicon.sym file,
• Now you may use these in your .map file LAYER as below.

For each Elgin Roadworks layer you wish to display you will need to add a LAYER entry into the .MAP file.

You may copy the following Snippets into your .MAP file using the Map Editor in Studio.
