I have downloaded OS MasterMap stylesheets from OS/Github.

How do I apply them in QGIS, all I get is style code rules for each symbology? see below picture example from Topo area file.

OS MasterMap Topo Area Rules

Your screenshot looks like you're most of the way there, the Rule column is looking at the style_code field and saying every feature with the attribute of 1 will be displayed as a Building.

Of course, this assumes you have data in the correct format and has the relevant fields in the attribute table - which it should be if it has been provided by the OS, but is not clear from your screenshot.

Take a look at this doc from the OS for more info:

https://www.ordnancesurvey.co.uk/docs/user-guides/cartographic-stylesheet-user-guide.pdf

It goes through the steps required to apply the .QML files (stylesheets) from GitHub to your data, and will hopefully clarify if you're still having issues.

  • Hi I downloaded OSMM data for my area of interest in 2015, there is no style code column, I have tried looking at guides on github/OS but can’t work them out – Jonathan Hallam Mar 21 '18 at 8:17
  • It looks like the field was added not long after you downloaded the data to help improve displaying the symbology: ordnancesurvey.co.uk/forums/discussion/1009066/… I think your best bet is probably to contact OS and see if they can provide an update to your data, or a way to attach or generate the style information information:ordnancesurvey.co.uk/contact/email-phone.html – MAJ742 Mar 21 '18 at 11:44
