DDS Web Services

DDS Web Services is an HTTP enhanced interface to Drill Down Server® (DDS), offering speed and flexibility to developers of location-based applications. It leverages the advantages of a web services architecture such as faster development times, better interoperability between disparate platforms, easier component reuse and friendlier protocols and data formats. It is specifically tailored for web-based applications with easy-to-use administration tools and simple URL generation.

DDS Web Services complies with the OpenGIS Consortium's (OGC) Open Location Services Initiative (OpenLS) 1.0 XML interface specification. It also includes advanced features not found in OpenLS 1.0, as well as "preview" features that may be found in future versions of the specification. deCarta is an active member of the OpenLS Working Group, assisting in the definition of the next version of the standard as well as OpenLS interoperability and compliance testing.
