[RNFdev] Some thoughts of FSA Centroids and Polygons

[Dan Putler]

Hi Dave,

I'm unclear on a couple of things. You indicate:

> 3. in a GIS import both the reduced RNF and the FSA centroids
> 4. do some queries:
>         a. find all polygons with one FSA point
>         b. find all polygons with more than one FSA point
>         c. find all polygons lacking any FSA tag
> 5. use this info to help with manual edits.
What I'm confused about two things. First, which polygons are you  
referring to above? The reduced RNF contains only road segments and  
other lines (not polygons), FSA centroids contains only points, or  
are you referring to the CSD polygons? The mention of FSA centroids  
leads to my second question, specifically, are the FSA centroids the  
ones available from geoconnections? If yes, they appear to have some  
accuracy issues.

I've also been thinking about other things we could that would be  
easier than creating FSA polygons. I have an idea, but I don't know  
if it feasible.
