Is there an app for creating notes? 14 days ago

Vespucci will allow you to do that.

However this is currently works slightly different than the normal editing mode and requires a mobile data connection (the Notes code is currently in the process of being refactored and will allow pre-survey bulk down- and post-suvey upload in the next version, similar to the normal editing mode).

Naturally if you are using vespucci you might as well directly add the stores to OSM.

After the release is before the release :-) 24 days ago

I haven't made any measurements in absolute terms yet, but the big win is that the refactoring of the auto download code (and when done of the notes code) allows the whole thing to run without the screen on. Obviously that is a net win wrt battery life in any case.

As to bandwidth, you can still simply download an area in advance or even simply have a set of JOSM compatible OSM files on device (this currently isn't possible with Notes, but that is one of the major reasons for the refactoring, so will be in the release).

Initial activity and retention of first-time HOT contributors about 1 month ago

What is the split in absolute numbers of the total of ~1500 for starting in TH, ER and MM?

I find your interpretations of the results rather biased, for example an alternative explanation for the lower (HOT, not OSM in general) retention rates of TH and ER could be that the more experienced contributors prefer mapping on their home turf to staring at not particularly good images of places of which they have no 1st hand experience. Obviously this would not be something that effects the majority of MM contributors due to lack of any other experience.

Don't know what to think of it of this research about 1 month ago

@escada could you please forward a link to the changeset in question to the DWG so that the account can be permamently banned.

MapBox and MapQuest ... the bit the tech pundits are missing about 1 month ago

@imagico it is undoubtably quite legit for MapBox to control what others can easily use of the technology they have developed (well in most cases it is more continued development of projects that existed pre-MB). The blog post was more about cutting through the haze of rethoric camouflaging completely conventional business practices.

And as you point out, the basic underlying business model is not really new, it is just that the trade rags have lost track of what the previous dozen of buzz words for the same were.

I don't have an opinion on if there is space in MapBoxes niche for more than one player at this point in time. What is however clear is that the easy available capital in the states makes it extremely difficult for any European company to compete, not that any of the other players have indicated that they really want to do so.

Experimented on Mapping By Photo-geotagging about 2 months ago

I would recommend to use either OpenCamera as the camera app (records the orientation of the device and has a setting to only take photographs when the device has a GPS fix) or use Mapillary.

While it is true that you will typically not get the best position accuracy by taking out the device waiting for a fix and pocketing it again, the trick is to capture enough context that you can use aerial imagery too to identify exactly where the relevant object is. For example if you are taking a picture of a shop, take a picture of the whole building too so that you can identify it from the roof shape etc.

Upps, that comment was from me ,,, used the wrong account.

Thoughts on the import of address nodes in JOSM using MassGIS L3 Parcel data to aid in adding addresses to buildings in MA 2 months ago

While for once this seems to be a technically competent import, you seem to have ignored essentially all non-technical prerequisites http://wiki.openstreetmap.org/wiki/Import/Guidelines

I would, very strongly, recommend that you immediately catch up on the stuff that you haven't done up to now.

Update JOSM to fix the Java Logjam 2 months ago

Small note: if you are using oAuth there is no real need (need as in privacy/security concern) to use SSL to communicate with the API.

Post scriptum to "long time - no edit" 3 months ago

@Vincent well I'm not convinced our conversion rate -needs- improving. It would naturally be nice.

I should point out that the end of 2011 we had roughly half a million accounts (500'000) so the 2'848 is actually 0.5% of that, even more if you deduct the already active mappers from the 500k. So we should expect this number to coninue to increase in absolute terms.

long time - no edit 3 months ago

See http://www.openstreetmap.org/user/SimonPoole/diary/34941 for some numbers.

long time - no edit 3 months ago

@curmet in many legislations that would require an explicit opt-in, which we currently don't even ask for.

Is it the moment for OpenStreetMap? 3 months ago

If I was given to +1ing stuff I would +1000 the above.

PS: the actual licence change took three years but the whole process started in 2007 and took more like 5 years....

Hide existing edit 3 months ago

First way to solve the problem: zoom in more.

2nd way: use JOSM.

JOSM has a display/edit filter system that can reduce clutter somewhat, however -please- only use it if you know what you are doing. But even without filters JOSM tends to be less stressful than online editors once you get over the initial learning to use issues.

How we apply map feedback 3 months ago

@PlaneMad offering the option -after- submitting a report is naturallly not really a solution, offering it as an option at least somewhere during the process would be.

How we apply map feedback 3 months ago

@mikelmaron in case you hadn't noticed, there has been a "Report a problem" page on openstreetmap.org for quite a while that anybody can link to from their map/website see http://www.openstreetmap.org/fixthemap It might profit from a more structured way of submitting notes, but that is a more general issue with the notes facility as it currently stands.

BTW there are good business reasons for MB to direct map feedback through their support group (lead generation, early detection of customer issues and so on) that does not mean it is necessarily a good thing for the project as a whole.

How we apply map feedback 3 months ago

The problem with the whole concept is that it doesn't provide for the conversion of a map user with an issue to a map contributor who can fix an issue themselves.

Or put differently it removes one of the important incoming routes for recruiting new mappers.

As is, the whole process is very much at odds with the basic concept of OSM.

Weitere Tests mit OSMAND (Android) Fahrspurassistenz 4 months ago

Das Abkürzen über off-on-ramps ist ein bekanntes Problem, iMHO müsste das Abbiegen selber höher bestraft werden, dann sollte das Problem eigentlich verschwinden.

It's time to import TIGER address ranges into OSM 4 months ago

Just two comments:

  • given the lesson that should have been learned from the original TIGER import, just because a dataset looks reasonably in one place, doesn't mean it isn't aboslute rubbish in a different corner, it is unlikely that you will find a consensus for a wholesale import
  • there is nothing stopping anybody from using brain + TIGER address ranges as a reference to add house numbers, perhaps OSM-US coule provide the data in a digestable form (aka overlay or similar)
Addresses Revisited 4 months ago

I'm not quite sure why it would be an "uphill" battle given that it tends to become easier with more data.

True it is a lot of work, but as Germany shows (roughly 1/4 the population and 1/5 or so of the addresses) it can be done in a reasonable time frame even when the majority of addresses are not imported. Given the wealth of PD data in the states, it should be a no-brainer (the data can be used as reference even if it is not imported directly).
