As I write this the server the files are hosted on is generating "reduced" copies of all the county files. All the files that were there are now in a folder called "full". Full seems to be fine most of the time and is ok for smaller counties, but if you're having trouble, then try the ungeneralised reduced variant.

If anyone is using the script: it has also been vastly improved. I got rid of that awful console menu in favour of passing options in via command line arguments.

Just to log the change here for anyone using this script. I have changed the name of the townland polygon objects to include the string "name", rather than "TD_ENGLISH".

This allows the datasets to be used with WME Geometries (Timbone's script) without having to alter the script in any way.

I have also regenerated all of the available townland geometry files available at https://waze.cw1998.uk to reflect this change. So any files downloaded from there should now work straight away with the script.
If there are any problems with this, let me know here or by PM.

Naming of minor country roads that have no other known name.

Thanks for this KDDA. We can't legally use data from OpenStreetMap in the Waze map though - we're limited to publicly available sources that have no usage restrictions on them. I can't remember exactly how OSM's data is licensed, but I'm pretty sure using it in Waze would contravene their licensing conditions.

However, from this page:

OpenStreetMap Legal FAQ wrote:3b. If I have data derived from OSM data, do I have to distribute it?
The license does not force you to distribute or make any data available.

But if you do distribute or publicly use anything derived from it - a Derivative Database - then the derivative database must be available under the same licence as the OSM data (the Open Database License).

We would have to make the Waze map data available under the OSM license if we were to use the OSM data in the Waze map. Since we're just volunteer map editors here and don't work for Waze, and since the Waze map is legally the property of Waze, we can't force Waze to make their commercial product - the map - openly available under the OSM license.

KDDA wrote:To use the Open Government Data Licence requires you to have the following attribution statement "Contains Irish Public Sector Data licensed under a Creative Commons Attribution 4.0 International (CC BY 4.0) licence" - https://data.gov.ie/pages/opendatalicence

Therefore, surely the use of this data would also contravene the Open Data licensing conditions?

The difference is between making derived works publicly available and between attribution. The other difference is that we're using the the townland geometry data to make a tool usable by map editors for visualising townland boundaries, which is something that's already visible in the out-of-copyright Ordnance Survey maps from the 1800s. We're not actually copying townland geometry data into the Waze map.

You do raise a good point though. I seem to recall we discussed this quite a while ago, and at the time I think we put an attribution statement in the Waze wiki. Most of the Ireland pages in the wiki have moved over to Wazeopedia and been rewritten (or are in progress), so we need to check out if the attribution statement has got lost.
