Importing Geographic Markup Language (GML) Files
Concept Procedure Quick Reference

GML (Geography Markup Language) is an OpenGISĀ® 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.

You can import and export GML in and out of AutoCAD Map 3D.


With AutoCAD Map 3D, you can import GML version 2 or version 3. There is a separate drop-down option that also allows you to import Ordnance Survey of Great Britain MasterMap GML version 2 files.

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 Customizing the Import and Export .ini Files.

Driver Options

GML has no import driver options.
