6. Converting Catalogs to GML/XML Format

7. Catalogs to GML/XML Format Downloaded catalogs are converted to GML format. This allows us to  Have a common data format  Use native XML Databases like Xindice or Sleepycat.

8. GML Format GPS Data 01AUG23 -5.20310199631932 0.766566081927471 7ODM RAD

10. Add GML Data to XML Database

11. XML Databases The System supports both Xindice and Berkeley XML DB (Sleepycat). We have Web Service interfaces to manage the XML DBs.
