Editing OSM data via QGIS?

[mattmakesmaps]

Hi All,

I’m starting to get back into editing OSM data online and I’ve been
using Potlach thusfar. I’m curious if there are any plugins for QGIS
that will allow edits/updates on OSM data?

My interest was sparked with this article on integrating OSM data into
QGIS:

http://mapperz.blogspot.com/2009/11/openstreetmap-data-on-demand-with.html

I was also wondering if there are any OSM mapping parties going on in
the Seattle-area these days?

thanks,
matt

I too am very interested in whether any OSM mapping parties are happening locally.  I had checked a couple months ago, and it seemed like there had been a few in the past couple years, but nothing recent.

Is there a local OSM representative of some sort?

I'm in, 3 makes a team and I bet we could round up even more.

This would be a blast.  Maybe we should take a closer look at the OSM data for our area and identify what features are most sorely lacking?  Or do you have a pretty good sense of that already?

I’ve not followed OSM as closely as I perhaps ought to – what sort of skills and/or gear would be needed to participate?

We should pick a place that would be fun to walk and bike in that looks sparse and see what kind of impact we can have. Although because TIGER has been imported, more fixing may need to be done than adding features.

There is a plugin in QGIS 1.3 for downloading and editing OSM data.  I havent used it yet, nor have i heard much about it, so who knows, but it'd probably be worth checking out.

also, Id be up for working on some local data too.

Good resources:

As far as the QGIS plugin, yes it should allow editing as well but I've yet to play around with it either.

So for fixing, we should make sure that we have some decent aerial photos to overlay onto.  Maybe serve them up via WMS? Then we could use them in QGis to overlay the vectors onto them.  As far as mapping new features, maybe one of the islands could use help?  ;)

Yeah, I could vote for Bainbridge!

[Roger André]

According to the wiki documentation that Dane sent out, a pub appears to be a critical requirement.  Does Bainbridge have a pub?  ;)

Conveniently, we’re now set up with 20 Trimble Juno’s (Mobile GIS/GPS
devices) at our Center at UW. I’d be happy to add 5-10 units to the
effort (w/ the aforementioned pub requirement clause). Granted, it's
going to be a whole lot easier if we use ArcPad (aka mini-ESRI) to do
the mapping...it's not wrong if you don't have to pay for it, right?

Wow I'm so excited that people are interested in getting involved.
While I was at ASU last year, cloudmade sponsored a number of mapping
parties around the Tempe/Phoenix area. I wonder if they have any
interest in sending an 'ambassador' out our way? They usually pick up
the first few rounds of beers and appetizers after the event, too!

[mattmakesmaps]

I forgot to mention that they also bring GPS units... haha.

One thing I've been thinking of, for a couple years actually, is whether we could use some basic remote sensing to help expand the OSM data set in areas that are not easily accessed?  I've been playing around a bit with just identifying water features, and it seems possible to get *ok* results.  Would certainly speed up "first cut" identification of certain things.  No?

You should have pretty good luck identifying water from ASTER data -
it's really absorptive in the IR bands that ASTER uses. There's plenty
of literature out there on the topic, and OSSIM or GRASS would likely
handle it OK. Downloading all the data is probably the biggest effort
- doubly so since you'd probably want to combine scenes across a
couple different times to get the best results.

Were you thinking of trying some automated classification or manual digitizing?

I don't think automated pixel based classification would really work since different road materials have different spectral signatures and they are not unique, not to mention obstructions such as trees, buildings and cars.  some sort of image segmentation/object oriented classification might be more effective, and ive seen a couple papers on this, but its not an easy problem to solve.  using imagery to manual digitize roads could be productive as a first step but in areas with a lot of tree cover smaller roads can be pretty thoroughly obscured.

this is something i've been thinking about recently because we've been talking about how to map private road/stream crossing to identify potential fish passage barriers.  i wonder if any one had other thoughts on the subject.

LIDAR is a huge help... the resolution is much better than most
multi-spectral imagery, and you can "see" through the vegetation. If
you couple that with multi-spectral from ASTER, SPOT, and derive slope
and a morphometric classification (using something like LandSerf) you
can pull some pretty useful stuff out. I've had very little luck from
the traditional pixel based classifications, but using Feature Analyst
or Definiens (both proprietary... there's an open source alternative
called Spring that is still a bit rough) I've had luck extracting
trails, roads, etc.

Yes, absolutely, if done with love :)

Oh, and another great recent article (and a different angle) regarding OSM:

http://community.cloudmade.com/blog/2009/10/29/heard-about-the-atlanta-mapathon-and-want-to-set-up-your-own-–-here’s-how/

- Can't wait for the pub,

[Greg Corradini]

Are there any tentative dates for this OSM project yet? I'm new to
this group and want in.

Out of the meeting last night we talked about contacting CloudMade to see if they would like to help us host an OSM mapping day in Seattle.  They have done this in other locations and helped with the organization, GPS units, and training of editing and uploading.  One of us will contact them soon and give an update here.  All ideas about where and what we might be interested in mapping are welcome… would be good to have a focus.

On the subject of ways to add content to OSM maybe we should consider
mobile phones as an alternative (after seeing what CloudMade has to
say about a geo party of course):

1) CloudMade now has POI collector app for iPhone --

2) I use the Vespucci OSM Editor on my Android OS.
