Wishlist: GPX tracks analyzer 9 months ago

I'm working on something along those lines:

Though it's not really designed for "batch mode" as the results do have to be analyzed slightly to see what's wrong.

I'm hoping to expand its coverage to more countries soon.

The third (Alex's) photo there is an excellent photo. It's a bit like an osm last supper.

Learning about paths about 1 year ago

Generally (and this will probably start an argument) paths are used out in rural areas where designations aren't so strict (or present at all).

In towns and cities where things often seem to be designated one way or another, people tend to break down into footway, cycleway etc.

GeoGit and GitHub Geo about 1 year ago

I've previously put a lot of thought into what's preventing OSM from using a Git/DVCS/DAG-y type model and what makes OSM & large scale geodata fundamentally different from a large software project. The conclusion I came to wasn't that it was the size of the data that was the important factor, it was the number of contributors. Sure, we know that Git-managed projects can practically scale to hundreds, perhaps thousands of contributors. But tens of thousands? 100,000? Without the process becoming chaotic and necessity of (sometimes complex) "merges" scaring off users?

Because in OSM you essentially have tens of thousands of users editing the same "repository". And with that you'll have an awful lot of merges to do, whether they're semi-automatic or not.

(these really are rhetorical questions - I would love to find out the answers)

Warning: GPS tracks recorded with an iPhone can be a waste about 1 year ago

Yes, many satnav systems in particular have been known to do this when collecting gpx traces. The concern is more than just that of accuracy - it's also potentially a copyright problem: are the traces now a derived work of the Apple road network? (that's a rhetorical question - I don't think anyone has the answer)

It's amazing how far sixteen lines of c++ can get you. about 1 year ago

Those are some interesting idea there Alex. I suppose the difference between the approaches is like that of bottom-up change and top-down change.

I know the idea of air-quality-aware routing has been kicking around for a while - in fact I think Martin from cyclestreets would love to be able to add it to their product if he had the right data (& time to add it amongst all his other feature requests).

As for c++, well, y'know, none of us were born knowing c++. You just kind of decide to sit down one day and figure it out. The conceptual wall between programmers and non-programmers is imaginary.

Yes, I think the jacket-wearers have chosen to abandon stealth and decided that the best place to hide is in plain sight.

Sounds like exactly the sort of place we should be having mapping parties then.

Using OSRM to improve road mapping quality over 1 year ago

I'm also working on improving mapping quality using OSRM, see

Unfortunately due to infrastructure constraints the prototype is only running on the british isles at the moment, but I'm working on expanding that.

Mapping a Community Center over 1 year ago

You absolutely can tag things with dual functions, just not if they both collide using the same key (amenity=...).

One of the alternatives would be to create two objects right next to each other but that's also a bit nasty because we like to follow a principle we call,_one_OSM_element

Mapping a Community Center over 1 year ago

@curiousscholar this is a bit of a "known issue" with our tagging scheme (particularly "amenity"s) - ideally you'd be able to tag something as both a place of worship and a community centre, but of course since both features use the amenity= key, that doesn't work. There has been talk of using ; separated multiple values, e.g. amenity=place_of_worship;community_centre, but little if any software (such as renderers) interprets/supports that.

The spelling of amenity=community_centre is of course also another display of the curious britishisms that infest osm.

Probably more information than you wanted there.
