Hi,

i test the IdentifyTask on ArcGISLocalDynamicMapServiceLayer with different Polygons. The executing time is depend on complexity of polygon. Simple Polygon (such as Rectangle) is very fast (30 ms), on a more complex Feature the executing time is 5000 ms and on Freehand-Polygon is the executing time very slow (10000 ms).

Environment:
Windows 7 64 bit
QT-Application: 64 bit
IdentifyParameters
EsriRuntimeQt::IdentifyParameters params;
params.setGeometry(mapPoint);
params.setMapExtent(m_pMap->extent());
params.setSpatialReference(m_pMap->spatialReference());
params.setMapHeight(m_pMap->height());
params.setMapWidth(m_pMap->width());
params.setLayerMode(EsriRuntimeQt::IdentifyParameters::VISIBLE_LAYERS);
int dpyX = QApplication::desktop()->physicalDpiX();
Q_UNUSED(dpyX)
int dpyY = QApplication::desktop()->physicalDpiY();
params.setDPI(dpyY);
params.setReturnGeometry(false);

              _task = EsriRuntimeQt::IdentifyTask(localDynMapSrvLayer.url());
              _task.executeAsync(params);

The ArcGISLocalDynamicMapServiceLayer has one Layer(feature class in a file geodatabase) with 10 Features.
I try also _task.execute(params) with same result.

Thanks in advance

Hello,

I'm trying to reproduce this on my end, but I cannot load the provided ArcGISLocalDynamicMapServiceLayer (mpk) because it does not contain a valid full extent.  The extent values come back as NaN.  Could you please provide an updated mpk?

Thanks!

Thank you Jan.  This is a bug on our end.  The task is not honoring the "returnGeometry" parameter.  Therefore, it attempts to return the entire geometry for each identify task, even though you have set the returnGeometry to "false".

I am fixing this for the final 10.2 release.  Thank you for your feedback and finding this issue!
