Half Day Introduction to GML for XML-Aware Business Managers
This half-day course is designed to provide XML-aware business managers with a detailed overview of the Geography Markup Language (GML). GML is quickly becoming the key technology for all geo-spatial data formatting. This XML application enables users to deliver geographic information as distinct features, and then control how they are displayed in a Web browser. Furthermore, since GML is an open standard (free, easily accessible) it enables this data to be readily shared and exchanged over the Internet. Participants will come away from this course with a good understanding of GML technology, along with knowledge of its applications.
