I wrote a small gdal python script for this, gdalsetnull.py, a simple command line program to set specified raster value NODATA, without creating a new raster. The easiest route to installing GDAL on windows is via OSGeo4W. Examples:
python gdalsetnull.py foobar.tif 0 # pure black is transparent
python gdalsetnull.py foobar.tif 0 255 0 # ...

In concept, you need to figure out what pixel values represent cells with no data and then edit your color table to assign the RED,GREEN,BLUE (RGB) values in the color table to be 255,255,255 for that cell value.
If you don't have the appropriate license to do this in Arc, you could use the gdal_translate tool (one of the gdal/ogr commandline tools)

I think you'll get it along with the Java Development kit. Found this on the ArcGIS Resource Center:
During ArcSDE client installation, the following files are installed:
jsde_sdk.jar - Contains the ArcSDE Client, and Geometry Java API class files.
jpe_sdk.jar - Contains the ArcSDE Projection Engine Java API class files.
concurrent.jar - ...

Actually, the link you found through googling is a bit misleading. I was having this same problem after i installed it. What i did was to replace the "localhost" withing the jetty.xml file with "0.0.0.0". This host parameter does not mean what IP to allow through, it means it will listen on that particular interface IP. So it's not "your IP" really, it's the ...

The WMS specification is all about delivering images to the client, not feature (geometry + attribute) data. Although I have not used GeoNetwork in this way before, I do not think there is a simple way for GeoNetwork to get the vector information out of a WMS service.
GeoServer also has a WFS service; I believe that if you are to use that service, you may ...

It looks like GeoNetwork along with some python can be used for this sort of thing. This post on "Converting FGDC XML metadata records for WMS and WFS services to ISO 19139 via Python and GeoNetwork" should give a start.
GeoNetwork did at one time apparently have issues with 10's of thousands of records, but I'd hope they're fixed based by now (that ...

There are errors that one can get due to several wrong bits. Please refer to the help page Identifying geometric network build errors. Most often these errors have to do something with errors in features' geometry.
I would start with:
1) Click Customize > Toolbars > Geometric Network Editing.
The Geometric Network Editing toolbar is added to ArcMap.
2) ...

I've looked into this a lot too, and have come to the conclusion that it's not possible. The only way of doing it seems to be to create wms/wfs services from your postgis data, using geoserver or mapserver (for example) and then harvesting the metadata from these using geonetworks harvesting options. There are still some caveats to using this approach, which ...

Geonetwork's default configuration tries to put H2 database files directly in /var/lib/tomcat7, which is not writable by the tomcat user. You need to change this to a location that is writable, and that is persistent (won't get overwritten by a redeployment). A simple solution for this is using the tomcat user's home directory.
First, make sure your tomcat ...

Yup got the answer. It is cascading service and also it's main advantage,
If you don’t manage or have access to the remote WMS, you can now manage its output as if it were local.
Even if the remote WMS is not GeoServer, you can use GeoServer features to treat its output (watermarking, decoration, printing, etc).

I don't know for GeoNetwork, but a CSW compliant request should probably look more like the following:
http://serverurl/geonetwork/srv/en/csw?
REQUEST=GetRecords&
SERVICE=CSW&
VERSION=2.0.2&
namespace=xmlns(csw=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2F2.0.2)&
OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&

You'll need to fetch the latest war file and unpack it in the webapps folder. The easiest way is to stop jetty and delete the geoserver directory and then use zip7 (or similar) to unpack the war file (make sure it ends up in a directory called geoserver).
If you have not moved the data directory from it's default position you will want to do that first. ...

Finally this is being implemented. The 2.7 trunk version of GeoNetwork has this capability. It's called "OGC WFS GetFeature harvesting". You can specify the query on your PostGIS and map those fields to metadata using a template.
More info in the Harvesing Documentation:

I think I'm having a similar problem. @underdark- the problem is that geonetwork is set up by default to display data in EPSG 4326, but for the UK we want it in EPSG 27700, as that's what our data is projected in, and we would also like a more UK-focussed extent, rather than the whole world. You can add the additional CRS in config-gui.xml, but there are ...

Besides that you preferred NOT to create a new SLD file, here is a blog entry on how to convert the internal colormap of a GeoTIFF to a SymbologyEncoding/SLD and define another colour there. In the derived SLD it is easy to define exactly which values to render with a 100% transparent color.

I don't need it for the moment but it seems Geonode is a way to get a solution
(http://projects.opengeo.org/CAPRA/wiki/CSW_client_implementation_guidelines)
I've only heard of this project. If someone have more informations, I will be happy to get them too.
