Hello fellow GDAL users!
I need to handle Change Only Updates (COU) for the UK Ordnance Survey MasterMap Topography Layer, and I was wondering how to approach this. Both the initial and COU data are supplied as GML, and I am currently converting the initial data to ESRI shapefiles using ogr2ogr. However, the ogr2ogr "-update" option won't update the shapefiles using the COU data - unless I'm missing something? I currently see two ways of overcoming this: 1. Use the COU data to update the initial GML data, and then re-convert the merged data to ESRI shapefiles 2. Use the COU data to directly update the ESRI shapefiles Obviously the second approach is more efficient, but how difficult is it to create, update and delete features using the GDAL python library? A few pointers for how to achieve this would be most welcome! :-) Warm regards, Jez -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Handling-Ordnance-Survey-Change-Only-Updates-tp5427706p5427706.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
