[Talk-us] Where are my local mappers at?

[Martijn van Exel]

Inspired by Dennis's talk at SOTM US and ensuing discussions I decided to
dust off some old code that tells you what your local mapping community
looks like. Here's what LA County looks like:

http://mvexel.github.io/bravemappers/#

Here's the source data:

More background in a diary entry:

Let me know if this is fun / useful and if you have suggestions for
improvement.

Re: [Talk-us] Burning Man old data, publicity opportunity

[Dale Puch]

A bit off topic here, but all the tools for making and running an OSM
database are available and opensource.
I'm not sure if it is a good or bad idea for OSM but other layers of data
could be developed and stored on other servers.  That would keep OSM
focused, but allow for more esoteric datasets to be layered on top of it.
My vision of that is having the tools and rendering pulling data from both
datasets, but it could also just use the OSM tile server with the extra
dataset rendered on top.
Licensing compatibility/compliance would have to be observed if it used any
OSM data or overlays vs. a clean dataset.

Re: [Talk-us] Burning Man old data, publicity opportunity

[Mikel Maron]

Hi Rob

Let's talk. Lots of cool opportunities. I put the data from past years data up, 
years ago. I'd like to get those years, and other years, available on an 
archive tile server - mini site ... perhaps OpenHistoricalMap if we can get 
that running again ... or just on it's own set of static tiles, generated 
through TileMill or such. There's also loads of aerial imagery to host together 
as well.

The data for each year is relevant beyond the one+ week the festival is open. 
All the planning, build up of the city, take down of the city, and looking back 
... well I think we can properly get it going on a yearly refresh schedule, 
maybe in line with opening of ticket sales in January or announcement of the 
street names.

Getting the data is the complicated part. There's release of the details of the 
city layout and core services, the fence are released sometime in May, by 
contacts at DPW. Artery placement later. The most sensitive data are the 
details of camp layout, which are always hard to get, but there are ways to 
gather it. For all these, there connections that have gone quiet to revitalize.

Anyhow, I'd love to support this, if yourself and others are taking the drivers 
seat.

-Mikel

Richard is correct, but I want to expand a little on the term 'historical'.
Data that has been mapped in OSM but deleted since is gone from the map,
but still in the database. It is not easy to get it out, but it can be
done. There are 'full history planet dumps'[1] that contain every version
of every node, way and relation that have ever existed in OSM - including
things that are long gone. If Burning Man artifacts were tagged
consistently, you could use a tool like osmium / osmjs to extract them.

I agree with both Richard and Serge that we should not purposely map things
that are not there, are ephemeral in nature, or keep things on the map that
are gone in reality. Burning Man, to my mind, represents an edge case -
it's a big event, people build stuff, it has a distinct geographical
presence even if for a short time. I'd love to see it mapped but also
deleted afterwards, as should the old BM sites in OSM.

Hi Robert,

Take Brad's advice and have a look at the earlier part of this thread.
 We, OpenStreetMap contributors, love to have enthusiastic newcomers
join the project.

Your particular interest does intersect with some issues that you
should be aware of.

Firstly, OpenStreetMap is primarily for geographic information that is
permanent, verifiable and significant.  Some might find the temporary
town for BM as not-permanent-enough.  Others will disagree.  :-)

Secondly, OpenStreetMap data is supposed to be current, rather than
historical.  There is a separate mailing list for those with an
interest in OpenStreetMap and historical objects.  The two older
version of BM map are an exception in OpenStreetMap data, and
sometimes lead to confusion on that matter.

Thirdly, acquiring a shape file to put some externally curated data
into OpenStreetMap is what we commonly refer to as an import.  There
have been many past imports with poor results, even from experienced,
well intentioned contributors.  So all prospective imports must follow
guidelines carefully, and with detailed community participation.

Now, I hope that the above information does not put you off
OpenStreetMap.  I'm not sure what the timing is for BM this year and
if you'll have time to properly consult on an import.

Regarding a source of shapefile data, you can find shape files of
various portions of the OpenStreetMap data set at the Geofabrik
downloads server.  http://download.geofabrik.de/north-america.html If
you were to chose the Nevada file, you might be able to get the
historic BM data from there.

If you want to make the current burning man map data useful for
attendees this year, you might consider converting it, alone, without
any integration with OpenStreetMap data.  if you were to convert it
for use on handheld GPSes, or pre-render it into tiles for a browser,
you could offer that as a download for other users before they head to
the desert.  You might also have copies on SD card, or USB for them
you copy from you once you are on-site.

Have a great time.

Best regards anf happy mapping,

Richard

Re: [Talk-us] Burning Man old data, publicity opportunity

[Serge Wroclawski]

I have to say that I have very mixed feelings about Burning Man being in OSM.

While I think that it's interesting because the event is so large and
there's potential utility, there are two things that bring me a bit of
concern:

1. Based on past years, the data is added but not deleted. The event
lasts one week, so even if you were to assume that it took time to
remove the various structures, the majority of it is gone, if not
entirely removed from the landscape, then it's at least gone in
functionality by the end of the event, and thus needs to be removed
from OSM. Burning Man's website on exodus states that the event should
ideally leave no trace. The same should then be true in OSM- the data
for the event should be gone as soon as the event is over.

2. In OSM, we map things which are permenent, and Burning Man's
transient nature puts it right on the fence. If I saw a sign for a
"Weeklong Sale" on the street, I'd be disinclined to map that sign.
But then again, if I knew that a major road was temporarily out due to
flooding, I'd indicate it.  HOT mapping of temporary structures would
work the same way- I'd map them, despite being temporary. This issue
of permennce and prominence is somewhat of a personal call, but
because Burning Man is transient by design, it bears mentioning.

So if it's valuable to Burning Man attendees to add it to OSM, and
it's meaningful, etc. then I don't see a problem, so long as it gets
cleaned out of OSM afterwards.

- Serge

You could contact the organizers or frequent participants ( there are
several list serves) and ask if anyone has any GPS traces or KML files.
Probabilistically, there may be some GIS attendee that has converted those
to a shape file - especially since there is a raft of Federal Permits
involved ( see http://igargoyle.com/images/City.jpg and  )

The Burning Man event has been a target for Remote Sensing platforms to
demonstrate sensor capabilities - For example, see the TerraSAR-X radar
satellite 
http://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-1775/#gallery/3558
and
Digital Globe
http://www.gettyimages.com/detail/news-photo/this-is-a-satellite-image-of-the-burning-man-festival-in-news-photo/158209283
 and http://www.gearthblog.com/blog/archives/2011/09/burning_man_2011.html

If you get the historical coordinates and dates of past sites, you can do a
multi-platform multi-sensor search on the NASA and ESA data portals.Perhaps
get some geo-referenced imagery and trace those. Landsat has a repeat rate
of about two weeks, BM itself is a week and prep probably starts earlier
than that ( like laying out the streets), the weather is generally clear,
so you probably have a good chance of finding something.

Re: [Talk-us] Burning Man old data, publicity opportunity

[robmorgan78]

Hello everyone, I am doing a project in my GIS class that involves working
with a shape file and exporting to a KML file. I have been going to Burning
Man for the past few years now and thought it would be interesting to work
with data from BM. I stumbled across this discussion and now instead of one
question I have two... 

First question, does anyone know where I can get shapefile data from past
Burning Man events? 

My second question is, I am going to Burning Man this year (2014) and would
be very interested in helping OSM with data collection. Who and what would I
need to do to get involved in helping OSM with data collection at Burning
Man 2014? 

-Robert
