Also, I did some research - while there is currently no Zillow map
API, they explain that they retrieve boundary data for each household
from county records. Each county stores the geocode info for each
point in a property boundary. I think this is publicly available in
most counties - Zillow has just gathered it all in one place.
If one could access this information, in conjunction with coordinates
of ward and stake boundaries, one could do a full plot map of a ward.
I have a feeling zillow will release a map API eventually though (they
already have an API for their home estimates) - once this is done, you
can use their API to see each household, house numbers, and then tie
it into your own programming to store info about each individual in a
ward.

Currently the church has two GIS analysts/technicians that work on upkeeping
all boundary changes up to date. They work on a few other projects but, yes
the church does have the boundaries for all the units in the world (or they
are working on drawing them out). In any event, the only way you can get
the official boundaries is have your stake president make a request to
church hq. Then the GIS department will send the stake president a jpg of
the stake with the boundaries mapped out. However the last time I talked
with the GIS department they have been instructed by the brethern not to
realease this information to anybody but stake presidents. However if you
can get the jpg you could use a georefrencing program like
http://research.microsoft.com/mapcruncher/ to plot out the boundaries.
(Haven't used mapcruncher, need to verify that user is not uploading picture
to public view)
Also to note, now that http://wardmap.theballfamily.org/intro.asp has been
closed down there have been other alternatives. Such as
https://www.moregoodfoundation.org/wardmap/ by Richard K Miller
<[EMAIL PROTECTED]>. In this mashup none of the membership
information is kept by the site. It is being dynamically displayed.
For a more focussed use you could download many of the opensource GIS's out
there and map out the boundaries yourself. Search QGIS or Udig, or download
a 60 day trial version of ArcView from Esri.

Subject: Re: [Ldsoss] Ward mapping application
Along the same lines, I'm working on desktop app which shows a map of the
ward and where everyone lives. I use a Yahoo web service to geocode the
addresses, and then I use Geotools(http://geotools.codehaus.org/) to display
the map. One thing I would really like to add to my maps are the ward
boundaries. I would need the ward boundaries encoded as a shape file or at
least in some digital format, so that I could convert the data to a shape
file. Is there any chance that the church has this data and that an open
source developer could get access to it?
