Trouble with TimeExtent

GordonGordon — Sun, 11 Mar 2012 19:32:29 GMT

Hi,
I am new to this ArcGIS platform. I am trying to use the "Make XY Event Layer" tool in ArcToolbox.

Geographic Coordinate System: GCS_WGS_1984
Datum: D_WGS_1984
Prime Meridian: Greenwich
Angular Unit: Degree

when TimeExtent disabled features are in the right place (screenshot_1) and FullExtent of FeatureLayer is:
XMin: 115716.328446092
YMin: 69167.3639030093
XMax: 130316.86821459
YMax: 95787.5884387642

[ATTACH=CONFIG]12578[/ATTACH]

If TimeExtent enabled, features are in the wrong place (screenshot_2) and FullExtent of FeatureLayer is:
XMin: 30.35382
YMin: 59.7104
XMax: 30.6107
YMax: 59.9484

[ATTACH=CONFIG]12579[/ATTACH]

what am I doing wrong? What is the binding between TimeExtent and FullExtent?

Strange!

Your case looks very close of the interactive SDK sample, i.e. a base map layer in mercator projection and a feature layer in geographical coodinates.

The features should be returned by the server in mercator projection but it seems that in your case they are in geographical coordinates.

Could you give more info on how to reproduce this issue?

Thanks

It's true.
Base map layer in mercator projection and a feature layer in geographical coodinates. I simply don't understand how TimeExtent affects mercator projection. :confused:
I use the API version 2.2.0.629 and ArcGIS Desktop 10.

Sorry I can't figure out where your issue could be:confused: As I am not able to reproduce, it's not that easy.

Two tests that might give a clue:

1) Could you try to set the map extent in Mercator coordinates

Something like:

  <esri:Map x:Name="MyMap" WrapAround="True">
   <esri:Map.Extent>
     <esri:Envelope XMin="-15000000" YMin="2000000" XMax="-7000000" YMax="8000000">
       <esri:Envelope.SpatialReference>
         <esri:SpatialReference WKID="102100"/>
       </esri:Envelope.SpatialReference>
     </esri:Envelope>
   </esri:Map.Extent>
  ......

2) Could you try with ArcGIS SL 2.4 version?
By chance this might have been fixed in the latest version.

Thanks
