[Talk-GB] OS and OSM

Re: [Talk-GB] OS and OSM
Hi Steve, I have been asked by editor of the Cartographic Journal to write a short piece on the effect of the release of OS OpenData on the OpenStreetMap project, and I am just trying to gather my thoughts, and make sure I cover all bases. [snip] Not sure how relevant this is but I'd like to offer some pro arguments to certain aspects of OpenData. At the moment I'm working on combining the Vector Map District tile set with footpaths from OSM. Phil Endecott's UK Map App (mobile app doing a similar sort of thing - but no slippy map tileset) looks pretty impressive. I'm also starting work on an augmented reality Android app for walkers, for which I'm planning to use Land-Form Panorama height data. So - even if OS OpenData is not being used directly within the main OSM database - I would say that it provides valuable additional data for OSM-based projects.

Re: [Talk-GB] OS and OSM
Steve, In Southwark I experimented with bulk importing buildings auto-traced from OS StreetView, but gave up in favour of manually tracing from Bing imagery. I was supplementing both methods with ground surveys. I switched when I approached central London parts of Southwark, where OS StreetView is of such poor quality that it was fairly useless. In central and south Southwark I still think it provides a good first pass, which can be improved by tracing Bing imagery and ground surveys to refine shapes and add addresses. Browse around and judge for yourself. I would also cite the errors we have found in OS Locator as a reason for preferring ground surveys, using the OS product as a tool to indicate possible errors to check out. We found 56 errors in Southwark.

Can anyone point me to others who have explored the possibilities that OS OpenData provided - PARTICULARLY if they can evidence WHY it is NOT of value to OSM? OS Opendata gives us access to places we can't otherwise go, such as docks, but so does aerial photography. It provides features such as power lines and some water ways that cross land that we don't have access to. It gives us access to the official, up-to-date boundary data that is just not available in any other form that we can use. It is much more up-to-date than some of the aerials and some of the various forms of data have names on them (Streetview and Locator) though that does have some small level of errors. There is also the postcode dataset which is a valuable source of data that would be very difficult to gather exhaustively otherwise. On the down side the level of detail is low. The building outlines, especially houses, are clearly crude and only indicative. I have been adding buildings and, combined with a survey, addresses and it is useful to use OS Streetview where the aerials are too old to see recent developments or occasionally where buildings are hidden by tree cover, but generally Streetview is not as good as aerials, which themselves are not that detailed in some areas I'm interested in. The VectorMap is (counter to its title) really taken from a render layer. Waterways have annoying gaps where anything crosses them. Woods have somewhat chunky outlines and annoying gaps. StreetView has hints of tracks where the names remain but the track detail has been removed. The alignment of Streetview (against multiple GPS traces) is consistently off in the areas I've used, but that could be the way someone in OSM has used it. Aerials are also off, but not as consistently, which means always checking the alignment before use. Some of the datasets are more useful than others. BoundaryLine is very useful, VectorMap District Settlements by area seem to me to be total rubbish - horribly crude, undefined as to what they show and badly out-of-date. I think OS Opendata has been useful, but it has also attracted the armchair tracer. Much of North and North East Lincolnshire is only in OSM because it has been traced from OS OpenData. All of the detail from a ground survey is missing, yet the map looks quite complete at first glance. According to Jerry's blog ( http://sk53-osm.blogspot.com/2011/02/updating-pub-density.html ) Grimsby has no pubs, this because Grimsby has been traced not surveyed. OS OpenData made this possible but it is not directly responsible. -- Cheers, Chris user: chillly ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

In fairness you should mention that the Bing imagery was not available at the time of the original OpenData release. It's clear that the simplified Street View building shapes are inferior to high-res aerial photos that Bing has let us use. But back when we only had the low-res Yahoo photos, the Street View building shapes were very useful and typically superior to the early OSM building tracing efforts. You mentioned errors in OS Locator, and it does indeed have some, but typically fewer errors than a single-pass ground survey (this based on my experience rechecking mismatches across London). It is great to do a ground survey and then use OS Locator to check for mistakes, but it would be equally possible to populate names from OS Locator and then do a ground survey to check for mistakes. The total amount of work involved is the same, but by kick-starting from the OS data you get to the 90% mark faster, even though the final 10% takes time. Again, I would re-iterate that the OS Locator names usually have a lower error rate than OSM ground surveys, so I would have more confidence in a street name populated from OS only than in one that had been found on the ground but not checked against OS. -- Ed Avis e...@waniasset.com ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

But then, I am an incrementalist kind of mapper and I almost always work by refining and adding detail to areas already partly complete.

[Talk-GB] OS, OSM and field boundaries
Although the OS has at last been forced into releasing some data we have paid for, it is still withholding field boundaries (as per OS 1:25k). These are invaluable for footpath walkers in agricultural areas (i.e. most of England and parts of Scotland and Wales) even though inevitably out-of-date (and the poor registration between the rights of way GIS layer and the base mapping can all too often leave you backtracking after walking a few hundred metres on the wrong side of the hedge!). Clearly most boundaries cannot readily be surveyed on the ground by OSM workers (short of triangulation) although satellite mapping is a big help where licence-free and clear enough. (Nick and others - thanks for the great work). Sadly I still cannot really use OSM for footpath walking away from conurbations. On a smart phone the zoom limitations make the OS 1:25k mapping of limited use (although Multimaps' OS version is better). Google satellite mapping is often too dark to read out of doors (and tiles cannot be downloaded for outdoor use because of Google's fair usage terms - as I have learned the hard way after having my IP address blocked by Google for 24 hours!); Google Maps is of little use out of town. What is needed in OSM for walkers - but how to do it? (thanks to Nick and others for great work) is (a) contours and (b) field boundaries.

This isn't quite what you are looking for perhaps, but my main overriding thought on OS OpenData is that it would be almost impossible for the OS to give OSM so many benefits without helping anyone else. For all the kinds of data that OSM excels at - road centrelines, parks, footpaths, names etc, the OpenData can be a great assistance as part of our toolchains - helping us spot mistakes and omissions and so on. But all the products that cover these areas are pretty much useless in of themselves - the StreetView map is pretty dreadful to use, the vector products are all chopped-up features only suitable for rendering with the same scales and feature widths as the raster maps they have been intended for. So there's almost no chance that someone can build interesting and exciting things on top of these products without replicating all the work we're doing in OSM. As for the things we can't collect easily - boundaries, post codes and so on, these datasets are functionally complete, but were never going to compete with OSM. I think if I'd been asked to decide what to release with the aim of improving OSM while making sure its not undermined, I doubt I could have done a better job.

Rhhhttt - that's not exactly an interesting day out for most people. Walking round collecting street names. That is how I started in OSM and it is still today the core of my mapping activity.

For example, at http://www.openstreetmap.org/?lat=51.548234lon=-0.157174zoom=18layers=M OS Street View showed some extra roads which weren't mapped.
