Overview

Commercial tiled map layers can be used as base layers within MapGuide flexible layouts. Users can use MapGuide overlays with commercial map service layers(Google maps, Yahoo maps and Virtual Earth).

Motivation

Fusion provide a solution to integrate the commercial map services into standard template:

1. Add some script tags to index.html manually. These scripts indicate commercial mapping api providers and unique api keys supplied by these providers.
   

2. Modify the application definition to include the commercial map service layers.
   

MapGuide templates should have the capability to support the commercial map services too, and we also need to provide a more convenient approach to add scripts.

Proposed Solution

1. Save the commercial mapping api providers and keys as extension in application definition.
   

2. MapGuide templates load the extension information from the application definition , and add the script tags into index.html on demand.
   

So users just need to provide an application definition with extension, then they will obtain the commercial mapping services.

Implications

Just add a script tag into index.html of MapGuide templates, which used for loading extension information from application definition.
For those application definitions which do not have extenstion information, there's no additional burden.

Test Plan

Test 5 MapGuide templates(aqua, limegold, maroon, slate and turquoiseyellow) to verify if they could support the commercial map services.
