[Talk-GB] Property extents

[Gareth L]

I’d maybe see the benefit for this data in more accurate/consistent landuse=residential areas? The whole “do you include the road, or create the area up to the road” decision.

Even if it were open .. does OSM want it?

I don't see any specific tags for it?

And you do want to have them accurate and up to date.

Example of inaccurate property extent problems .. from Australia - https://www.news.com.au/national/queensland/news/coroner-hits-out-at-police-use-of-google-maps-printouts-in-search-for-missing-man/news-story/0d005d8018e694433313ab2b941c7df4

A recent coroner hit out at the decision to rely on Google Maps printouts in the manhunt — noting that Queensland Police Service (QPS) had better tools available to them to search the area.

In fact, the inquest detailed how officers on the case were later given a much more informative aerial map of the area from the local council, at no cost to police whatsoever.

“It is quite apparent the quality of the images of the property on this map is far superior to the Google map images used in the search of the property and one wonders if the same mistake in conducting a search of only half the property would have been made if this map had been obtained,” Deputy State Coroner John Lock said in his report.

There are lots of potential problems from mapping private property extents. Don't think I would want to go there.

Here's one of Jerry's blog posts about the not-so-open Land Registry data:

https://sk53-osm.blogspot.com/2013/10/not-very-inspired-land-registry-open.html

and my post about testing using them:

https://chris-osm.blogspot.com/2013/10/land-registry-inspire-polygons.html

As Tom says, these datasets are not Open Data and we cannot use them as a data source in OSM. I feel that the Open Government Licence should not be used in this case as it isn't  Open.

Hi Andy,

Both Chris Hill & I blogged about them at the time, but they NEVER had any semblance of being open data.

The same proved to be true of the Land Registry Prices Paid which now can only be used if you are an estate agent.

Owen has covered both on his Map Gubbins blog.

Have to dash, so no time to find the links.

As a follow-up, has anyone looked at the OGL licenced INSPIRE Land Registry index polygons?

Data is in GML format.

Agreed, though I wonder whether this will have any correlation with Land Registry. I'm guessing .gov isn’t that joined up.

Cheers
