Several basemaps in a one app

Question

Is there any tool that will allow to compare 2 basemaps? I need to compare 2 Arial imageries (they could be layers as well). Swipe tool overlaps layers, so I can only see 1 layer at the time, but what I need is basically divide a map into 2 parts with different basemaps.. Thanks!!!

Hi Larry, your Swipe Plus widget works perfect for me for this project. The only thing I wanted to ask you is there any possibility to  Select the layer I want to appear only to the RIGHT of the swipe bar. The widget settings only ask about LEFT side.

I need it in order to allow customer to choose from aerial photography's of different years. So they can compare 2013 and 2014, or 2015 and 1998..

Thank you very much in advance!!!!!!

I was about 75% finished with a new widget last June.  It's called Side by Side Overview Map.  The overview map can be resized to fill the right half of the screen and the basemap can be different that the main map.  Don't know if I'll ever have time to finish it now, but what I have done is available to any brave developer who wants it.

Diana,

The closest thing available is the eBasemap Gallery Widget. It allows you to select two base maps to fade between (notice fade not swipe).

Swiping a maps layers is VERY different from swiping the maps basemap as a map can only have one basemap at a time. I get past this in my widget by making a hybrid basemap containing the two selected basemaps and fading between them.
