SuperpOSe integration with Oracle MapViewer & GeoServer
Full styling for OS MasterMap layers loaded by SuperpOSe into Oracle is now available for Oracle’s MapViewer, and the open-source GeoServer product (via SLD files). This extends the styling support provided by SuperpOSe for providing identical styling support across numerous vendor’s packages. Both use PNG image files to provide support for rich-texture fill patterns.
Oracle’s MapViewer uses a series of tables under the user MDSYS; SDO_STYLES_TABLE (for individual feature styles), SDO_THEMES_TABLE (for assigning styles to features), and SDO_MAPS_TABLES (for grouping themes into a viewable map layer). SuperpOSe populates all three ready for use, with the same styles as found in its support for ESRI and MapInfo products, resulting in a styling that is visually indistinguishable.
The SLD (Styled Layer Descriptor) is an OGC-compliant styling file, built on XML code. SLD files can be used in a wide variety of applications, as they are a vendor-neutral specification, including GeoServer and Google Earth. Deployment consists of uploading the SLD file to the server, along with the corresponding PNG image fills, tying it to the data, and then the data is ready for presentation.
