I'm afraid I didn't entirely understand the question, but will try to<br>
give it a shot anyway.<br>

</div>When you say "could be used for a searchable GIS database"- what<br>
information are you intending to put in the database?<br>
<br>
That is, are you looking to collect names/addresses/etc of<br>
organizations, or are you looking for OSM as a base layer for display<br>
on the map?<br>
<br>
Looking at the site that you've pointed to:<br>
<br>
<a href="http://cna.civicore.com/customCode/map.cfm" target="_blank">http://cna.civicore.com/customCode/map.cfm</a><br>
<br>
It appears they're just using Google as a base layer, that they have<br>
their own database and then simply call out to Google to make the<br>
display.<br>
<br>
And if you're asking "Can we do this, but instead of Google, use OSM"<br>
then the answer is "Yes, absolutely, and easily."<br>
<br>
<br>
If you're suggesting instead that you'd like to use OSM as the one and<br>
only database, then the answer is a "Yes, you probably could, but it's<br>
not the right tool for the job."<br>

</div>If you just mean pointing to a location on the map (ie the first<br>
scenario I laid out) then I think the easiest thing to do would<br>
probably be to load the non-profit dataset, along with the address<br>
dataset (or congressional district dataset, etc.) into a PostGIS<br>
database, using something like GeoDjango to manage the database, and<br>
then have it handle calling out to OpenLayers or your display engine<br>
to display your data on top of OSM tiles.<br></blockquote><div><br></div><div>Being relatively new to OSM, I'm not aware if congressional districts are mapped.

<br>
</div>This sounds a bit more like the second scenario, so let's dive a<br>
little into that.<br>
<br>
First, when you say the data for Washington State is available, we<br>
have to be very careful about what exactly that means. In essence,<br>
you'd be doing an import into OSM, and generally imports have not been<br>
overall good for the project and are /generally/ frowned upon.<br>
<br>
Even in the best case, you'd need to do a great deal of work not only<br>
making sure the tags are right, as you point out, but also ensuring<br>
that the data you enter is not already present in someone else's<br>
contributed data. And you would need to ensure that the data is<br>
properly integrated, and then properly maintained, with a plan for<br>
handling updates.<br></blockquote><div> </div><div>Actually I had not even considered uploading the data. I was thinking of interns </div><div>and volunteers to add the data. They would need training of course. Doing the whole country </div>
<div>manually would be a challenge. Doing a single state might doable. </div><div><br></div><div>Steve Coast has this new tool that allows people to mark the front door location. If he could be prevailed upon to give us a version of his front door tool that would allow us to email and organization to have them move the marker to their entrance. </div>
<div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
After all this, you'd need to be aware that others might go in and<br>
change the data.<br></blockquote><div><br></div><div>I would hope so. I think that that is one of the biggest advantages of using OSM as the main </div><div>database. If someone in Roslyn, WA noticed that the food bank moved to a new location they </div>
<div>could just input the change. </div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
And we haven't even discussed the licensing issues.<br></blockquote><div><br></div><div>I need to make sure that the nonprofit organization understands the incensing of OSM data. Just because</div><div>I believe information wants to be free, doesn't mean they believe that.</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
I'd say that OSM is not the right choice for putting data in where you<br>
need tight control. You may find a way to make the model fit your<br>
need, but OSM's view of the world is shared contributorship and shared<br>
authorship, which in my experience does not integrate with the needs<br>
by some for only using authorized datasets put out by certain<br>
organizations.<br>
<br>
<br>
To summarize:<br>
<br>
I think OSM is a poor choice for storage and retrial of very specific<br>
data that needs to come from a specific, authorized dataset, but I<br>
think it's a great thing to make that data available to OSM to add in.<br>
I also think that OSM is an excellent choice for the display of that<br>
data either by overlaying it visually, or possibly (depending on<br>
license factors), for direct data integration on your own GIS<br>
database.<br>
<br>
Does that answer your question or did I miss the mark entirely?<br></blockquote><div><br></div><div>Great answers. Gave me plenty to work with. Especially the PostGis database software. </div><div><br></div><div>Thanks,</div>
