Specifies whether the tracking data in a dataset is Spatial or Attribute-Only.
Determine the Stream Layer type
//spatial or non-spatial?
if (streamLayer.TrackType == TrackType.AttributeOnly)
{
//this is a non-spatial stream layer
}
else
{
//this must be a spatial stream layer
}
Get The Track Type
var trackType = streamLayer.TrackType;
switch(trackType)
{
//TODO deal with tracktype
case TrackType.None:
case TrackType.AttributeOnly:
case TrackType.Spatial:
break;
}
Set Various Stream Layer properties via the CIM
//The layer must be track aware and spatial
if (streamLayer.TrackType != TrackType.Spatial)
return;
//Must be on QueuedTask
//get the CIM Definition
var def = streamLayer.GetDefinition() as CIMFeatureLayer;
//set the number of previous observations,
def.PreviousObservationsCount = (int)streamLayer.GetExpirationMaxCount() - 1;
//set show previous observations and track lines to true
def.ShowPreviousObservations = true;
def.ShowTracks = true;
//commit the changes
streamLayer.SetDefinition(def);
