To use the code in this topic, reference the following assemblies in your Visual Studio project. In the code files, you will need using (C#) or Imports (VB .NET) directives for the corresponding namespaces (given in parenthesis below if different from the assembly name):

• ESRI.ArcGIS.TrackingAnalyst
• ESRI.ArcGIS.Geometry

See the following sections for more information about this namespace:

• Tracking Analyst extension

Tracking Analyst extension

• Common temporal reference - Provides a single temporal perspective for all display objects in Tracking Analyst. When analyzing data from different sources, it's important to synchronize the data's temporal reference so the state of the data shares common references, such as a common spatial extent and a common temporal perspective in time. This feature provides the mechanism to allow the temporal objects to efficiently archive this common reference.
• Dynamic display manager - Provides a mechanism to automatically update the display at a configured interval and provides methods to allow other software components to request animation updates to the display in a synchronized manner.
• Tracking label engine - The display of dynamic labels on top of temporal-based objects requires the introduction of a special label engine. This label engine provides the capability to efficiently label features on the screen that change dynamically over time.

Temporal presentation

• Temporal feature layer - Based on the feature layer with extensions that enable the display of time series data. This layer temporally indexes standard ESRI feature classes that contain date and time data as one of their attributes and displays this time series feature class data in temporal order. This layer introduces capabilities to query such data for a given temporal extent and to temporally offset such data.
• Temporal legend objects - Provides capabilities to symbolize data based on temporal offsets from the current temporal perspective. These objects are based on ESRI's legend objects and can be extended to provide storage and temporal analysis of time data to determine what temporal symbology to use.
• Temporal renderer - Provides a container that allows you to configure the temporal layer to symbolize time series data using temporal modifications to standard ESRI event-based rendering. Temporal symbolization options include filter data, symbolize data, size a symbol, or color a symbol based on time from a reference time.

Tracking utility

[C#]

private string ConvertGeomToGML()
{
    IGMLConversion gmlConversion=new GMLConverterClass();
    IPoint point=new PointClass();
    point.PutCoords(55, 99);
    gmlConversion.ESRIGeometry=point;
    string strGML=gmlConversion.GML;
    return strGML;
}

[VB.NET]

Private Function ConvertGeomToGML() As String
    
    Dim gmlConversion As IGMLConversion=New GMLConverterClass()
    Dim point As IPoint=New PointClass()
    point.PutCoords(55, 99)
    gmlConversion.ESRIGeometry=point
    Dim strGML As String=gmlConversion.GML
    Return strGML
    
End Function
