This task allows you to generate trade areas based on predefined geographies. These geographies can be ESRI standard demographic layers.
To select standard geography records, a data table with geographic IDs must be generated from which to create the trade areas. This table will be used to select the IDs from the geography layer. Once selected, the features will be exported as a new feature class.
Alternatively to generating a data table, geographic IDs can be explicitely specified in the
geographyIDs array.
For example, if you want to generate trade areas based on a list of ZIP Codes, you would start by creating a table with all the ZIP Code records you want included in the table. This table may be a territory assignment file created by an external process. The ZIP Code records are then matched to the ZIP Code boundaries provided with Community Analyst, and a trade area is created with all matching ZIP Codes.
All non-matching ZIP Codes will not be included in the output trade area. Non-matching ZIP Codes are ZIP Codes that are not valid and do not have a corresponding feature in the input geography layer.
The result of this task is a TaskResultOutput object,
which is compatible with ArcGIS Server's mapping APIs. FeatureSet, MapImage, and an array of
ReportInfo objects can be returned in it depending on task output options requested.
Additionally, the output analysis layer and/or report can be stored to the Business Analyst Server repository.

public function get lastResult():TaskResultOutput| StandardLevelsOfGeographyTask | () | Constructor |
public function StandardLevelsOfGeographyTask(urlOrClient:Object = null)Creates a new instance of the StandardLevelsOfGeographyTask class.
A new task can be constructed in two ways: as a task sharing a BAServerClient type instance
with other tasks (the urlOrClient parameter has the BAServerClient type) or
as a standalone task encapsulating its own client.
The base URL to the Business Analyst Server HTTP Service looks as follows:
http://{host}:{port}/ArcGIS/baserver/REST/services/DefaultMap/BAServer
The {host} and {port} parameters in this URL should be substituted with
valid Business Analyst Server host name and port, respectively.
urlOrClient:Object (default = null) |

| createCommand | () | method |
public function createCommand(parameters:StandardLevelsOfGeographyParameters, commandName:String = null):BACommandCreates a new command encapsulating this task and the given parameters.
Parameters
parameters:StandardLevelsOfGeographyParameters — Parameters of a task to be executed.

commandName:String (default = null) |
BACommand — A new command.
|
| execute | () | method |
public function execute(parameters:StandardLevelsOfGeographyParameters, responder:IResponder = null):AsyncTokenSends a request for executing a Standard Levels of Geography task to the Business Analyst Server HTTP (REST) Service.
A response can be received in two ways—in an optional
responder object passed in parameters
of this method and/or in listeners of fault and taskCompleted
events registered for this task.
The responder is notified first when a response is received and parsed.
Its fault method receives a parameter of the FaultEvent type and its
result method receives a parameter of the BATaskCompletedEvent type
whose result property contains the result object.
After that the received event is dispatched to listeners of this task.
If a response is succesfully received and parsed, the result is assigned to the
lastResult property of this task.
Parameters
parameters:StandardLevelsOfGeographyParameters — Parameters of the task.

responder:IResponder (default = null) |
AsyncToken — Asynch token associated with the response.

| name | Constant |
