STORET Web Services
STORET now provides a suite of web services which provide direct access to data in the STORET Warehouse.
Please Note: These services have been revised as of February 8, 2008.
Revisions to the web services include enhancements in performance, additional web
methods, and enhanced request parameters. Please refer to the revised STORET
Web Services Consumption User Guide (see link below) for a description of the revised services.
What is a web service?
- A web service is a computer-to-computer protocol that allows for the direct sharing of information.
- With the STORET web services, applications may access data directly from the
STORET Warehouse without needing an authorized database connection.
- The STORET web services have different input parameters and pre-defined output formats.
The following list describes the most current web services available and each service's endpoint and output schema.
The service endpoints provide the WSDL (Web Service Definition Language) for each service as well
as the different operations and web methods each service supports. The output
schemas are a machine readable formal definition of the schemas that each service
will return as output. Please refer to the revised
STORET Web Services Consumption User Guide (PDF 641 KB)
for a full description of the services, including the required input parameters, as well as
examples of how to consume them from other applications.
Please note this document is draft and may be changed as the services are further tested and used.

STORET Result Web Service
The STORET Result Web Service provides direct access to STORET results.
*Please Note: The Result Web Service has been revised
(as of February 8, 2008) to provide for faster data retrieval.
Results may now be requested via latitude/longitude parameters,
or by the type of characteristic a user is searching for.
Please note that to ensure good scalability and availability,
the result output returned by the Web Service is configured to
be restricted by a maximum number of results (20,000).
If the number of results requested exceeds the maximum limit,
then the web method will notify the end user to narrow down
the search criteria in order to reduce the number of results requested.
Please refer to the draft STORET Web Services Consumption User Guide
(PDF 641 KB) for a full description of the STORET Result Web Service.
