Posts a query to a WhiteStar Legal2Map™ WebServices (WS3) server to obtain points or polygons matching a list of legal land descriptions.
A feature is emitted for each point or polygon returned from the query.
Parameters
Request Parameters
Request Description Attribute
The list attribute on the input feature that provides the set of textual property descriptions which form the request query.
If the list attribute contains a single element, and that element is an integer, it will be assumed to be the transaction ID of a previous query. In this case, a request will be performed to retrieve the results of the query corresponding to the given transaction ID.
Resulting Geometry Type
IfPointis specified, the submitted query will result in a set of points representing corresponding well locations. IfPolygonis specified, the query will result in a set of polygons representing the area described by the request.
Result Description Attribute
Name of the attribute that contains the legal property description for the output feature.
Result Transaction ID Attribute
Name of the attribute that contains a unique numeric identifier for the completed transaction.
Attribute to hold ERROR feature message
Name of the attribute that contains any error messages for the completed transaction.
Connection Parameters
Number of times to retry deferred results
Number of times to resend the query if results are not returned after the time specified byNumber of seconds to wait between tries.
Note: Queries involving deferred results are not currently supported, and may result in an error.
Number of seconds to wait between tries
Time, in seconds, to wait before resending a query if results are not returned from the previous query.
Web Service Host
The web service host name to send the query to. The query is sent to the web wervice host using basic authentication over an HTTPS connection.
Note: For access outside of your network using a proxy server, use the Network tools in FME Options. From the Workbench menu, selectTools > FME Options > Network. For more information, see "Network" in the FME Workbench Help.
HTTP Authentication Parameters
HTTP Authentication Username, HTTP Authentication Password
The username and password for authenticating the connection to the web service host.
Example
The query for well locations described by the queries "6 25S 21E 1 SE SE SE NW" and "6 10S 16W 2 C SE NE SW" is formed as follows:
- The input feature contains the attribute request{0} and request{1} with the values:
request{0} = "6 25S 21E 1 SE SE SE NW"
request{1} = "6 10S 16W 2 C SE NE SW"
- "Request Description Attribute" is set to "request{}"
- "Result Description Attribute" is set to "_description"
- "Transaction ID attribute" is set to "_trans_id"
- "Resulting Geometry Type" is set to "Point".
- Web service host, username, and password are entered for the target server.
