How can I get accurate locations in a forest ? 6 days ago

Getting good tracks in high foilage areas is difficult to very difficult and even professional grade equiment will have problems. The previous comments have already pointed I number of things out, a couple of more from me:

  • avoid wet weather (just makes the problem worse)
  • depending on the type of forest and where you live, surveying the tracks outside of summer/spring (aka winter, late fall, early spring) will help
  • using a ballon(s) may help
New MapRoulette challenge: TIGER Mismatched Ways 9 days ago

@pieren a bit late, but anyway: you do need to check a wider area around the location. One thing that is very common with TIGER is that the roads actually exist but are offset a km or so. Don't think GPS, think jotting down the approximate position of a turn off on paper.

MapRoulette Challenges 'Ways Needing Smoothing' and 'Crossing Ways' Completed 22 days ago

Martijn, congrats.

I may have asked this before, sorry if I have: the ways need smoothing task at least motivated some mappers (well at least myself) to clean up the surrounding areas (i remember correcting a larger city where all the roads were more than one block off, OSM based navigation devices would have miserably failed there), has there neen a noticeable improvement in routing quality in the US after completion of the task?

Copyright question about 2 months ago

Given the small size of the OSMF it is clear that we rely on some policing at a local level as long as we are talking about friendly reminders that attribution of OSM is required.

You should however be sure that attribution is actually missing. There is no requirement to up front declare that a product is based on OSM. Naturally it would be good form to do so, but we are not in the business of teaching people manners.

If there is no obvious and clear attribution in the app itself then it should be added.

... I would actually be surprised if we had an unmapped prison here.

No joy this weekend about 2 months ago

@Gerald I didn't say it was a minor problem, just that it is no different than anywhere else (and that it tends to get better over time).

Every new user is shown https://www.openstreetmap.org/welcome on first login, you might want to check if the Portugese wording is correct.

No joy this weekend about 2 months ago

As has already been said: the Brazilian community does not have a larger relative (to the existing community) influx of new users than others. See http://resultmaps.neis-one.org/newestosmcountry.php?c=Brazil given that Brazil is clearly less densely mapped that numerous other regions the "problem" if at all is smaller not larger than in other areas.

A ways to improve the situation is for example to send a (kind) welcome message to new mappers, at the same time you can easily check for any issues with their mapping..

You don't say which editor you are using, if it is iD see

the blogs are not really a good medium for such questions, I would recommend using the help site.

Opening Hours 3 months ago

The basic problem is that the grammar is just to complex. While it is nice that you can specify nearly everything it is riddled with special cases that make a complete implementation a pain. Further the available grammar spec seems to have errors (missing definition of ) and doesn't cover things that seem to be in use, like using "," as delimiters between rule-squences. WHich btw doesn't seem to be documented.

And then there is stuff like if you are reasonably lenient about what you accept, for example allowing naked hour values without ":", a legal spec like "11" becomes ambiguous.

Contributor numbers revisited and empty changesets galore 3 months ago

The bloat aspect is neligable, even though currently more than 10% of all changesets created are empty.

From an API point of view while the empty changesets could be discarded they can't being completly stopped from happening. They way to think of them is more: "setting a start marker", "adding edits", "setting a stop marker".

OpenStreetMap and the Open Data Movement 6 months ago

@lxbarth [sorry for the following bit of tongue in cheekness]

Hasn't the ultimate form of collaboration with government already been invented?

We pay them for their work.

Crazy TIGER 6 months ago

@dalek2point3 undoubtably TIGER is a great resource, and more recent releases are clearly a lot better for a large parts of the USA (there are still numerous areas where it is rather bad to say the least). But, as you point out, it is clearly not TIGER projects fault that we imported the data at a such early date. Further I don't think it is in any way fair to blame the importers, there seems to have been a community consensus that it was a good thing at the time.

What we shouldn't do however, is let political correct positivism get in the way of learning the many lesson we should learn from the TIGER import. For example don't hurry to import data when there is no immediate need, it is not going to go away and the next release will be better.

FIX THE MAP 6 months ago

Well the expectation wasn't really that it would be used as a short cut for people that are already mappers, but I agree we could simply display two buttons "Edit at current position" and "Create note at current position" and zap all the rest of the text for people that are logged in.

@imagico off topic, but as a pointer http://www.openstreetmap.org/user/SimonPoole/diary/21771 a fix the map page has been around for quite a while now.

Corrections 6 months ago

Hallo Daniel

Normalerweise sind Änderungen praktisch sofort sichtbar, allerdings kanns Gründe geben wieso es mal Ausnahmsweise nicht klappt. Der beste Ort zum nachschauen an was es liegen kann ist help.openstreetmap.org . Ansonsten ist es sinnvoll imger entweder einen Link auf den relevanten Changeset oder das Gebiet das du bearbeit hast anzufügen, ansonsten können iwr auch nur raten um was es genau geht,.

What kind of user/challenge stats do MapRoulette users want? 6 months ago

IMHO: KISS, completion percentage and absolute numbers over time is enough.

How do you map house numbers efficiently? 7 months ago

As long as you are still on the same street ,adding house number in vespucci is no more work than selecting the building outline or adding a node (long press), adding the tags by using the "repeat last tags" function and adjusting the number (around 3-4 clicks total). Every new road requires a bit more effort for the first address, but given the street name auto completion this is minimal.

This is naturally more effort (both clickwise and time) than with say keypad mapper for the surveying part, but you are already finished when you areat home and the addresses are where you really wanted them to be.
