switch basemap automatically

philippschnetzer — Mon, 19 Mar 2012 11:56:02 GMT

I remember seeing something similar in a previous thread but cannot seem to find it anymore....

I have two basemaps and would like the map to switch to "basemap1" when zoomed in beyond a certain scale (1:18,000). "Basemap2" is the Esri aerial imagery and there is very poor coverage in my area so that's why a switch to my custom "basemap1" would be ideal.

Thank you!

Philipp,

Yep the eMapSwitcherWidget allow for this to be setup. You need to Read the ReadMe.txt to see how to configure this. There is a config-fader.xml example of what need to be added to the MAIN config.xml for your viewer.

Don't forget to click the Mark as answer check on this post and to click the top arrow (promote) as shown below:

To do this, all you need to do is set the displaylevels for each of the basemaps in the <layer> tag. Keep in mind this only works with tiled and Bing layers. If you set the basemaps as the same name, they will show as one in the viewer. Then when you zoom in, depending on the level, you will see the particular service.

Robert,

I should have known you already had a perfect solution in place 🙂

Works beautifully!

Thanks

Chris - Thanks for your insight as well, for anyone not using Roberts eMapSwitcher your solution would do the job.
