How to Add Google, MapQuest or Bing Layers¶
Notes on All Layers¶
- Commercial layers can only be used as basemap layers. You cannot elevate them any higher in the list.
- Commercial layers cannot be printed. The licensing agreements for these layers do not allow them to be printed.
- You must shift your map into Web Mercator (aka “the Google Projection”). Please read Changing the Projection
How to Add Google Layers¶
Step 1: Add the Google API to geomoose.html¶
Open “geomoose.html” in a text editor.
Find the <script.. tag that contains ‘OpenLayers.js’ in the ‘src’ attribute.
Then add the Google API, the code should look like this:
<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAnfs7bKE82qgb3Zc2YyS-oBT2yXp_ZAY8_ufC3CFXhHIE1NvwkxSySz_REpPq-4WZA27OwgbtyR3VcA"></script> <script type="text/javascript" src="OpenLayers-2.8/OpenLayers.js"></script>
Step 2: Add the Google map-source Definitions¶
Now it is necessary to put the map-source definitions into the Mapbook:
<map-source name="google_physical" type="google" google-type="physical">
<layer name="all"/>
</map-source>
<map-source name="google_streets" type="google" google-type="streets">
<layer name="all"/>
</map-source>
<map-source name="google_hybrid" type="google" google-type="hybrid">
<layer name="all"/>
</map-source>
<map-source name="google_satellite" type="google" google-type="satellite">
<layer name="all"/>
</map-source>
Step 3: Add the Definitions to the Catalog¶
Google layers can only be used as basemap layers. So when using them as a background it is usually wise to simply create a backgrounds group and allow the user to toggle between the various layers:
<group title="Backgrounds" expand="true" multiple="false">
<layer title="Streets" src="google_streets/all" status="on"/>
<layer title="Physical" src="google_physical/all" status="off"/>
<layer title="Hybrid" src="google_hybrid/all" status="off"/>
<layer title="Satellite" src="google_satellite/all" status="off"/>
</group>
