[Accessibility] english: actual state of project Data from city map for barrier free mobility in augsburg, germany, was prevously: Daten aus Stadtplan für barrierefreie Mobilität aus Augsburg

[Dietmar]

Hello list-member,

i want to inform you a litte bit about the project, because the orginally
osm wiki page [1] is only in german available.

About two years ago, a project started at the locally university in augsburg
(at geographic computer-science department) to collect data from the inner
area in augsburg, how the (foot)ways could be used by persons in wheelchairs
or with walker (US) oder zimmer (GB) (in german: rollator). The city
government supported the university with money and with technical support
from their local geographic department.

Students from the university collected the data, based on some forms, which
detailted data to get. They took tablet pcs with onboard high resolution
bitmap pictures from air. The data went into an open licensed gis
(geographic information system) and additionally microsoft database.

The collected following data (each as different technical layers in the gis)
(sorry for unknown/bad english words in following):
* footway sloped curbs: footway segments, where they are be lower for
pedestrian crossing the streets or for parking cars on private ground (hight
of the sloped curb and transferse inclination)
* traffic signals for pedestrians, including kind of signals, buttons with
tactile and/or acustic sound for blind persons,
* footways and living streets without footways (some old small streets) as
areas with the information about surface and smoothness (some nice details
;) )
* amenities from public offices, tourism buildings and points, other
amenities like schools and churches with a lot details about accessibilty
(see below)
* narrow points on (foot)ways, where its smaller than 1.20m in width. Reason
are too small footways, signs as barriers, other things, which decrease the
width of the ways to lower than 1.20m
* tram and bus stops (with no relevant information) for the users in
wheelchairs and walker/zimmer.
* inclination of (foot)ways as areas. messurement in degrees.
* transferse inclination as areas. Most times, reason is a sloped curb oder
a bad builded footway.
* standard parking areas (multi-storey, underground) with or without
capacity for disabled persons and single special parking areas for disabled
persons only.
* a few gutter on a pedestrian way (old ways contain sometimes gutter to
collect rain water and to transport to underground), which are not so easy
to pass for wheelchair drivers
* benches
* steps on ways
* taxi stops
* public telephones
* public and semi-public toilets, which can be used with wheelchairs
* very detailed: the best useable way for a disabled person to an amenity
(described above). the entrance can be on ground, can have a single step,
more steps or a ramp to use with wheelchair/walker/zimmer.
* very, very detailed: the entrance door: turning-door, push-door,
practically useable width with wheelchair, how easy to open, auto-open
button and a lot more details

In total, the project has about 3.850 data records. one-third are sloped
curbs (not complete footways, only a short or longer way-part, where it is
lowered).

In a first step, i got the agrrement to import the data in openstreetmap
with our acutla cc-by-sa 2.0 license for a test area, which is about 15% of
the complete project area, with about 500 data records.

At the osm wiki page, i describe in german the details data structure with
all fields and their appearance as point data, ways or areas (closed ways in
osm) and the transformation from the project fieldnames to their equivalents
in osm, if available.
Some data don't have a tags in osm, so i took some temporarily tags and try
to discuss the future tags in osm (hard work, because of a lot of wiki
pages, which are available, but are not consistent).

Now, i'm nearly finished the inport, but not the integration of the data.
The sloped curbs are my biggest problem, because they are most of the time
only short segments, and i declared them as a new barrier type barrier=curb.

My actual todos are:
* integration of some layers (steps are not useable at all, because they
have not correct position)
* waiting for a further data source: i can get the public buildings with
city person contacts as polygons in a short time
* i try to build render rules for osmarend renderer. At this time, only to
demonstrate the possibility to build a map offline (unfortunately) and with
layer zoom 17 and 18 at this time.
* i try to build a map for my garmin gsp logger: both for integration of the
project data on field and for demonstration for late use by the disabled
persons.
* waiting for last questions about interpreting some detailes of the project
data by university.

Next steps:
* give the signal to the project members and demonstrate the kind of
integration in openstreetmap
* get the go signals for rest of data import
* continue the data collection (next year, a few times, in augsburg there
will be a few games of the women soccer world-championship. This is a big
push for the city government to get more data for disabled persons, because
they want to show their support to those groups.

I cannot translate the osm wiki page at all to english version, but hope,
that this post is enough for you to get informed about this osm import
project.

In the next days, i have to include the link to the osm wiki page
accessibilty, i forgot in the past.
