Smith,
 
The general approach taken is using line interpolation -
ST_line_interpolate_point(linestring geometry, locationfraction float8).  
 
So if you have a street say that has number
 
1 - 10 
 
and you know you want street number 2
you would take intepolated point  at position 0.2 along the segment.

Unfortunately we don't have any examples yet in the docs of that.

Subject: [postgis-users] Your opinion on geocoding ?


Hi,

Thanks, for your replies. I will like to ask for your own opinion as
regarding geocoding. Considering the limitations of my data. Which geocoding
method do you think will be appropriate ? If possible, if you have links to
papers on geocoding i will be grateful. Or do u think geocoding the street
names using the center point of the linestrings is the most appropriate
method ?

Thanks,

Smith Roman.
