GML (Geography Markup Language) is an OpenGIS® Implementation specification that defines an XML encoding for the transport and storage of geographic information. The specification can be found on the OpenGIS Consortium web site.
Because the GML format is flexible and allows you to specify your own schemas, semantics, and options, there are many variations of the format. AutoCAD Map 3D reads many of these, but some may not be compatible with the AutoCAD Map 3D GML driver.
In addition, before importing GML data in Asian languages, you must verify that the language encoding settings specified in the AutoCAD Map 3D mapimport.ini file match the settings in your incoming file. The settings must match for the import to be successful. For more information, see .
