CDAS Web Services
The Coordinated Data Analysis System (CDAS) Web services allow a software
developer to use CDAS services in their own application. If you are
not a software developer and simply want to use the existing web interface
to CDAS, then return to the
main CDAWeb page.
CDAS supports simultaneous multi-mission, multi-instrument selection and
comparison of science data among a wide range of current space missions.
While CDAWeb provides access to this data through an HTML-based user interface,
these Web services provides a distributed programming interface to CDAS.
If you are developing an application that requires science data from
any of the data sets held by CDAS, then the CDAS Web services will provide
an interface to the data for your application. Higher level Web services
that perform additional processing of the data are expected to be added
in the near future. The following describes how to utilize these
Web services from your own application.
Software Development Kit (SDK)
The CDAS Web services SDK consists of instructions and a library to allow
a developer to utilize the CDAS Web services. The SDK is

While the Web services are accessible from any language/run-time that support
the Web services interface described by the above WSDL, the CDAS Web services
SDK contains a Java class library to simplify using the CDAS Web services
from a Java client. The description of this API is included in the
SDK download file but may also be viewed online at the following link:
