How to display townlands in WME
Posted: Wed Apr 25, 2018 2:48 pm
Hello,
This thread will outline how to view townland boundaries in WME using a script written by Timbones, which can be found here.
There are a number of options available, each with their benefits and tradeoffs:
On my machine, I find that loading files over 10MB causes things to slow down, but of course, this varies between machines.
Downloads
You can find all the files you need at https://waze.cw1998.uk. This is just a directory view, so you need to right-click on a file and click “Save link as…” (or your favourite browser’s equivalent) to download the file.
You will also need to install Tim’s WME Geometries script.
Instructions
Tips
If you are experiencing performance problems loading in larger counties, try disabling some layers. If you are only adding in roads, you won’t need the places layers for example. Also, try the generalised files if you are finding the ungeneralised files unusable.
Don’t load in more than one county at a time. There is no need unless you are working along a county border. Click the ‘Clear all’ button to remove the current county if you are changing to a different one (or reload WME).
Screenshots
Some before and after screenshots can be viewed in the spoiler (click the image to view full size).
In these screenshots I use the ungeneralised Co. Clare boundaries. Performance is acceptable, but it is noticeably slow when zooming in and out. Panning around wasn't a huge issue.

There are a number of options available, each with their benefits and tradeoffs:
- Generalised boundaries (20m or 50m) - More performant, less accurate boundaries
- Ungeneralised boundaries - Less performant due to large file size, but provides precise boundaries in WME.
