Importing Ordnance Survey Vectors

The OS Mastermap vectors are in a GML format. To read them into most GIS systems they need to be converted first. There is a script which will convert the vectors into ESRI Shapefiles - GML2Shape.sh. This uses the ogr2ogr utility which comes with GDAL.


Procedure

To convert the OS vectors, copy them off the DVD into a directory. Then run:

GML2Shape.sh <shapefilesdir> <gmlfilesdir>

where <shapefilesdir> is a directory path where you want the shape files to go to (they will overwrite any files with the same name - suggest you use an empty directory) and <gmlfilesdir> is the directory path where the GML vectors have been copied to.
