[postgis-users] Geoportal Server vs Postgres Geoportal

[Paragon Corporation]

Nicholas,
 
Not too familiar with Geoportal Server. 
 
pgsql2shp is what I commonly use for light-weight data dispensing from web
apps.
 
In php I just call it using system(..) function
 
using code something like
 $shell_cmd = "pgsql2shp  otherpgsql2shp_including sql"
 system($shell_cmd);
 
Usually I predump the data the user is viewing working on tagged by user
session in a staging table and the query just outputs the data based on user
session.
 
In ASP.NET I use System.Diagnostics.Process
 
As far as other tools that can dispense files OGR2OGR part of GDAL package
can output more formats and I think internally is what Mapserver uses for
its WFS 1.1 custom output format option
 
http://mapserver.org/output/ogr_output.html#ogr-output
 
 
Geoserver can also output WFS requests in Shapefile and other formats:
http://docs.geoserver.org/latest/en/user/services/wfs/outputformats.html
 
Though overall I prefer the simplicity of pgsql2shp especially for
outputting complex user map queries.
 
Hope that helps,
Regina

If this is the wrong place to ask this question, please point me in the
right direction!

I'm very new to databases and GIS.  I'm researching geoportals and how they
offer geometries for download.


As I understand it, Esri's "open source" Geoportal Server is the standard
method of offering data for download (besides offering shape files for
download as a file...like the census website).  It is a software layer on
top of the database that allows you to select the geometries you want by
drawing a polygon.  It also manages metadata and offers some search methods.


But it doesn't allow me to make awesome sql queries.  So I want to use
pgsql2shp to allow people to download the geometries.   Are there any
reasons why I shouldn't offer geometry downloads from a postgres database
using pgsql2shp?

Also, are there any examples of what I'm talking about now?  Are there any
postgres dbs that allow for direct download of geometries? And don't use
esri geoportal server?

Thanks!

-Nicholas
