Eric,
I'm not sure if its any value to you, but the PostGIS 2.0 we upgraded the
Tiger geocoder to load in Tiger 2010 data. We only loaded in the datasets
that were relevant for geocoding, but the system is table driven, so you
could use it to load the other datasets you care about.
Hi,
thanks for the reply but I do not have a Start Database Icon. I think a DB
was never yet created as PostGIS Installation fails, because the Server created
by pg Admin III can not connect.
Is it correct to use default settings?

Did you install PostgreSQL?
It sounds like you need to learn the basics of Relations Database
Management Systems (RDMS) before you dive into PostgreSQL/PostGIS.
The server is the database system. It manages connections to the
databases. If the server isn't running, there's nothing to which you

when I am using ST_Difference(), I often have the problem, that the
resulting geometries contain vertexes lying outside of the supposed
geometry extent. My impression is that the function tries to preserve
vertexes of the input geometries and does not check properly, whether

Hi Birgit,
this is only a topoligie Problem. Your secound polygon is computed outside
PostGIS and numeric precision are lost by import. In this case ST_Difference()
and other PostGIS function can have results with very small errors.
You can clean the second polygon by move all points to the
Thanks for all the suggestions.
I first thought about doing the simplify, but after some reconsideration I
realized that this would change the geometry of the country borders, and
Area measurements might be wrong.
Then i tried the query without the ST_Intersection and only the conditional

I have a project on my desktop gis which I would like to transfer to the web

Hi,
I have installed PostGIS 1.5.2 on a PostgreSQL 9.0.4 (OpenSCG RPM) on an

that I should perform make install as postgres user. This didn't work
and generated the error below:
/bin/mkdir -p
Correction: that was PostgreSQL 9.0.3
Sorry!
