Loading and displaying GML Data

Loading GML data into ArcGIS

The GML data can be imported into ArcGIS using the Quick Import function in Arc Toolbox. The data will be imported un-styled. Users should also note that due to the large file sizes of some of the 100km2 grid tiles especially SU and TQ, this import may take time to process.

ArcToolbox Quick Import tool

The quick import will create a special file geodatabase into which to import the data. Once the quick import function has been completed, the data can be added using the usual ‘add data’ button in ArcMap and selecting all of the layers from the newly created file geodatabase;

Add data file explorer window

The resulting imported data will then appear in the ArcMap window and can then be styled according to user requirements.

The data can also be styled with a suitable ArcGIS layer file for OS OpenMap-Local previously created or styled manually using the styling tools provided.

Loading GML data into MapInfo Professional

OS OpenMap-Local is supplied in GML version 3.2.1. At the current time, most versions of MapInfo Professional will not import this version of GML data. Version 12.5 of MapInfo Professional does read the latest version of GML data but this has not been tested. The only alternative way of loading GML data to MapInfo would be to use third party translation software. Some of this is open-source and some is commercial.
