ability to rotate map

JasonTrook — Thu, 06 Mar 2014 15:46:39 GMT

Hello,
Is it possible, via a widget or other means, to rotate the orientation of my map. By default north is at the top of the screen but I would like to be able to view my map facing E, S, W and other directions too.
Thanks,
Jason

Yes.

In the viewer you can set the map rotation in the main config file to be whatever you want. See the documentation at http://resources.arcgis.com/en/help/flex-viewer/concepts/index.html#/Map_content/01m30000005p000000/

You could also create your own widget that support changing the rotation interactively. There's an API sample that does that: https://developers.arcgis.com/flex/sample-code/map-rotation.htm (move the "N" on the rotator circle in the upper left to rotate the map interactively).

Hi Bjorn

I was able to able to migrate the sample to a compiled widget.

By the way, the tool is not interacting with the map. I can rotate the "wheel" , I can click on "N" to center the weehl. But nothing happens in the map. I suspect that it's because I've ommitted the following line from the sample (I didn't figure out how to implement this part in to the widget):

<esri:center>
            <esri:MapPoint x="-10051125" y="4669530"/>
        </esri:center>
        <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>
    </esri:Map>

Here is my code :

<?xml version="1.0" encoding="utf-8"?>

<viewer:BaseWidget xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:esri="http://www.esri.com/2008/ags"

xmlns:viewer="com.esri.viewer.*"

xmlns:components="widgets.RotateMap.components.*">

<fx:Script>

</fx:Script>

<esri:Map id="map"

</esri:Map>

<components:RotationWheel id="wheel"

width="75" height="75"

left="20" top="20"

change="map.rotateTo(wheel.mapRotation, wheel.mapRotation == 0)"

mapRotation="{map.mapRotation}"

skinClass="widgets.RotateMap.skins.RotationWheelSkin"/>

</viewer:BaseWidget>

Any tip on this issue?

Thanks in advance

Question solved, I was totally misunderstanding the concept between a sample and passing into a widget format. I just had to remove the class esr:map and voila, the Rotate Wheel interacts with the my WebGIS application.
