[postgis-users] Geocoding

[Doug_Newcomb at fws.gov]

The Tiger data is getting better.  At least here in North Carolina, the
Census Bureau is working with the local county governments to produce an
enhanced TIGER dataset .   7.6 meter accuracy for roads.  They want to be
done by 2008.

I think that the task of geocoding is fairly easy and I have written a
geocode function that uses PostGIS. However, the problem is where to get
the data. In the U.S. you can use Tiger line data from the census, but it
is horrible inaccurate.  If you have resources you can purchase more
accurate data from other companies like Navteq, or manually correct the
census data.

Subject: [postgis-users] Geocoding

Does/Will PostGis have a Geocoding routine built in such as ArcSDE has
locators and geocoding processing?  I am curious, as geocoding is the
building block of any GIS work I do and I have need of decent open-source
solutions that can process millions of records in a batch mode, or can be
implemented on the WEB as a “geocoding service” either again in batch mode,
or real time via other web-based applications.  I understand the
limitations of this functionality in an open-source environment, namely the
ability of getting decent reference data, but am curious all the same.

Maybe a module could be built that accesses the geocoding services provided
by Google or Yahoo, of MS Virtual Earth??????

Just thought I would throw this out there.
