I see a lot of varied mapping practice in the US while engaged on TIGER
fixup (trying to make it routable for bikes), much of it very good, which is
leading me to the conclusion that the density argument is mostly a red
herring.

Anywhere with a population of 3k+ should be able to support an OSM volunteer
or two[1]. Most people in the US, and most people in Europe, live in such
places. Indeed, the US has hundreds, thousands of such local mappers: there
are great examples of small-town mapping all over the US and it always
cheers me up to stumble across them.

55% of Montana's population lives in urban areas, compared to, say, 67% in
Wales. It's less (and there are differences in methodology) but it's not
_that_ much less. There is no density reason why Billings need be less well
mapped than Bangor, Kalispell than Carmarthen, or Missoula than Machynlleth.

That leaves the rural areas, which are big and empty. But, and you'll excuse
me stating the blindingly obvious, the thing about empty areas is that
there's not much there to map. The TIGER A41 issue continues to be a running
sore but, by and large, this can be (and is being) armchaired.

I hope you are not referring to the building import nor the landuse
import from AND.
Which is/was crappy data and still requires cleanup in the northern

I agree with that. What I've seen from the TIGER data it is not 
conducive for a good mapper ecosystem. Yes, it will function to show a 
map that is moderately accurate, it might function if you want to use 
the data for routing purposes and maybe even for guided navigation, but 
virtually all information needs fixing so the amount of work you have to 
do to get a correct map is still humongous. And then you get parts which 
are corrected and part which are not and the casual dataconsumer can not 
really distinguish them.


Compare that with the AND import of the Netherlands where the data was 
accurate and needed only minor fixing but where the bulk has just been 
untouched (except for adding metadata) and is still the base of the map 
in the Netherlands.


So the one import cannot be compared to the other and conclusions drawn 
from one can not be extrapolated as being the truth.

This thread started when I said that imports can often be damaging to
community building, and people innocently asked if I can back that up
with facts or research.

Now of course it is extremely difficult to do research in this
particular area at all; you can't just design an experiment and let it
run for 10 years and see what happens. That we have any research at all
about this topic, and not just anecdotes (of which there are of course
many), is very valuable.

Of course it is always very tempting to discredit research that doesn't
agree with one's strongly held beliefs. "When I said show me some
research, I meant THE OTHER KIND of research!!!" - I would probably
start looking for flaws in a study that branded a data import as a huge
success kickstarting a vibrant community too ;)

Anyway, I'm fine with a discussion based on gut feelings and anectdotal
evidence. Just don't ask me to prove my point with research if you're
not interested.

I find it fascinating how much effort you put into the attempt to 
discredit the paper this is about.

But what you write is ultimately mostly a collection of unrelated 
trivialities and assumptions that do not actually manage to question 
the methodology used in the paper.  There are aspects you can 
rightfully criticize about the reasearch work documented in the paper 
but to do that you would need to look deeper into what the author 
actually did instead of musing about the motivation for plane trips 
across the US.

I am not really sure what you actually want to say here.  You clearly 
try to discredit the paper cited and you also attack Frederik for 
linking to it.  But if you truly think the paper is nonsense and you 
know all this stuff so much better why don't you write your own paper 
pointing out the errors and explaining how things really are?

Just criticizing people is cheap if you don't expose yourself by making 
your own analysis and your own statements others can review and argue 
about.

The only statement beyond the superficial criticism in that regard i can 
read from what you write is: Mapping in the US is hard.  That is of 
course by definition a subjective statement so no one will seriously be 
able to argue with you about that.

And if you want to know about how to successfully map and build a local

Let's take the Arizona county I map out of, Maricopa County[5], the 
Arizona county just north of me, Yavapai County [6], and Switzerland[7] 
to see the basic flaws in this research.  5/8th of Switzerland fits in 
my county alone.  Adding Yavapai County's size to Maricopa County's size 
we now have all of Switzerland covered and the combined population of 
Maricopa County and Yavapai County adds only a 228,168 increase to 
Maricopa County's population.  The study says that both Maricopa and 
Yavapai county should perform the same.  Following this I have always 
heard from European's that the American's should perform the same just

Christoph,
As Simon said, I believe there may be some validity to Abhishek Nagaraj's
findings on ownership.  It's why so many people watch edits in their area.
They are quick to challenge poor edits in their watch area. I believe they
have a sense of ownership in the area. It's an attribute that would be nice
to encourage. I think of it more in terms of stewardship rather than
ownership, but either way, OSM benefits.

Frederik,
Abhishek Nagaraj, the author of the study you mentioned, presented [1] his
findings at the SotM-US in Boulder. I had a chance to ask Abhishek about
his research findings. What he said is that how the import is designed has
a lot to due with how they impact subsequent edits. In the case of the
TIGER import, the counties with poor data [1], suffered. Counties with
better (I'd never say good) did not. The poor TIGER counties saw few road
attributes, like surface= tags, added.

In contract, after the Building and Address import in Seattle, users
commented how much easier it was to add poi information. The import does
not seem to have impact user contributions. In fact Seattle has a very
active OSM community. Many factors go into why Seattle is successful. The
high tech presence in the area, the OSM Meetup group, the active OSGEO
community, and the communities willingness to get involved. The
building/address import was just one small part of the equation.

I wouldn't reject the "ownership" hypothesis because of the large, and
increasing, amount of churn. As we know that "most" data is contributed
by fairly small number of contributors and they could well be longer
term contributor too. IIRC there is at least one paper co-authored by
Pascal that has numbers on this, maybe it is worth the effort to dig
that out again.

That said there are obviously other mechanisms that could produce the
measured effect.

Very interesting.

As additional summary: The analysis made is based on the original Tiger
import which produced a different level of completeness in different
areas due to differences in the source data and thereby offers fairly
well defined starting conditions for a comparative analysis.

The analysis and the observations coming from it look pretty solid.  I
am not fully convinced by the interpretation of the reasons lying
largely in contributors taking 'ownership' of the data they contribute.
This would in my eyes - at least if meant in terms of individual
ownership - require the original contributors at the beginning to
continue to be significant in terms of overall contribution volume over
the whole time span analyzed.  This seems rather unlikely considering
the active contributor turnover we have in general
(https://wiki.openstreetmap.org/wiki/File:Active_contributors_year.png).


So, survey performed on a society where internet access is common.
If the survey were performed where internet access is very rare (satellite 
only) the the conclusion may be different.

Very interesting.

As additional summary: The analysis made is based on the original Tiger 
import which produced a different level of completeness in different 
areas due to differences in the source data and thereby offers fairly 
well defined starting conditions for a comparative analysis.

The analysis and the observations coming from it look pretty solid.  I 
am not fully convinced by the interpretation of the reasons lying 
largely in contributors taking 'ownership' of the data they contribute.

[OSM-talk] Scientific paper on "Information Seeding"

2017-10-09 Thread Frederik Ramm
Hi,

today I was pointed to a recent, open-access scientific paper called
"Information Seeding and Knowledge Production in Online Communities:
Evidence from OpenStreetMap". This open-access paper is available here

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3044581

In the context of armchair mapping, but especially of data imports (and
recently, machine-generated OSM data) there's always been the discussion
between those who say "careful, too much importing will hurt the growth
of a local community", and others who say "this import is going to
kick-start a local community, let's do it!"

Until now this has been a rather un-proven matter of belief, and the
general mood is usually in favour of a quick build-up of data (through
remote mapping, importing, or machine learning) instead of a
take-it-slow approach that would wait for a community to form and take
matters into their own hands.

The paper quoted above uses OSM as a research object and finds that in
certain ways imports in OSM have indeed harmed community growth. The
paper attempts to provide insights helpful for all kinds of
user-generated knowledge projects (not necessarily OSM), and
draws the following conclusion:

"While information seeding could be useful to encourage the production
of distant forms of follow-on knowledge, it might demotivate and
under-provide more mundane and incremental follow-on information.
Accordingly, if managers are interested in leveraging pre-existing
information to spur the development of online communities, they might be
better served by withholding some pre-existing information and provide
community members with some space to create knowledge from scratch—even
if such knowledge already exists in an external source. This policy allows
community members to become invested in the community and develop
ownership over the knowledge."

Bye
Frederik
