Yes, that should be fine.

Other maps can be used when seeking certain talent for the ward (which is needed in rural wards), or to see if we are not properly taking care of new members that are located in far reaching locations. Such information with faith and the Spirit can powerfully inform decisions.

I am fortunate to have access to ESRI ArcGIS and sophisticated geocoding packages provided by ESRI and other geography giants through my appointment at the University of Virginia. (I believe ESRI ArcGIS can provide web services across a variety of enterprise architectures, although I imagine that the software is expensive .) However, I was surprised by the low rate success in my geocoding effort. I even tried some other web mapping service (similar to Kevin), such as Yahoo, Microsoft, and Google with even less success. The problem was that many of the addresses in the ward roster are ... "Box 1 Rural Route 3" or "555 Deer Farm Road"... Rural routes and farm roads do not exist in large-scale street files that are maintained for web mapping. (however, I must note that Google Earth was able to find quite a few - and must use a different map set or geocoding algorithm than their online mapping service.)

Geography is an important tool in making these decisions. I would recommend that the church investigate both commercial and open source options, while investigating what features to implement and how to do it to best meet the objectives of the church. However, I would recommend that if possible and feasible that the church team host geocoding web services internally - and NOT rely on the APIs or street maps of any particular existing web service.

They do bundle (starting with 9.2) map data from TeleAtlas with ArcGIS. So for now I'm using that to match most of the stake (slightly larger than Connecticut, covering almost all of Delaware, half the landmass of Maryland, and one school district in Pennsylvania.) I match three units a week that way, and then once in a while try to manually match addresses that fell through the cracks, against YahooMaps (which I've found is most reliable of the online services.)
JTaber wrote:In the past, I've based things more on census tracts and tried to see where our strengths are compared to population. But in many cases ward boundaries don't respect census tracts, and in Delaware neither do school districts. (At least they do in Maryland and Pennsylvania.) So for me, that's on the shelf for right now, but there would be great potential for someone at a higher level to maintain that sort of data.
JTaber wrote:Like I said before, I've had to play around with data sources to find something I can use easily. It's only because of what I have access to right now at work that things are going so efficiently that I can re-geocode all thirteen units in my stake each month. Personally, I feel that (and not just in the United States or other countries with similar levels of street data) the Church should generate latitude and longitude (or some equivalent) for each and every address. (Each ward and branch is supposed to have a physical address for each family as it is.)
