The version is 1.1.0rc1. Seems I need to specify both "prefix"/"server" and "ns_prefix/ns_ur" for it to work.. I am wondering why. Thanks.

Hi,
I understood that meaning was to put exactly one label per state. Each state, even tiny ones, should be labeled. But one state should get only one label even if the map window is splitting the state polygon into two or more intersections. Those intersections may be bigger than the tiny state. Not extremely simple.

Subject: [mapserver-users] How to label only largest displayed areas?
Hi, All,
How can I label only the largest displayed areas within an extent? For example, if I'm labeling states of the United States and my extent covers a small region around the Maine, New Hampshire and Massachusetts junction, I only want a single label for each state, chosen by the largest displayed area (within the current map extent) in each state.
I'm using spatial data stored in Microsoft's SQL Server 2008.
I've created an enhancement request ticket (#4173: Define a current layer extent's WKT string for use in Data statement) as one possible approach, but this approach requires a change to MapServer.
Is there a better way?
Thanks.

Hello All,
The problem got solved finally. It seems all I need to do is to add two more lines into my TinyOWS configuration. Maybe fixing the PythonPath helped as well. But this change is what really makes a difference.
Before (not working):
<layer retrievable="1"
writable="0"
ns_prefix="tows"
ns_uri="http://myserver:8080/"
schema="transit"
name="lrtstops"
srid="2227"
title="LRT Stops" />
After (working now):
<layer retrievable="1"
writable="0"
ns_prefix="tows"
ns_uri="http://myserver:8080/"
prefix="tows"
server="http://myserver:8080/"
schema="transit"
name="lrtstops"
srid="2227"
title="LRT Stops" />
I was relieved of the frustration I have been suffering during the past two days. Thanks everyone.
Ya

Several questions related to your issue:
- What TinyOWS version do you use ?
- What happen if you use QGIS as WMS/WFS client rather than OpenLayers ?
- Could you activate TinyOWS log and check if there's any error message in
it ?
- Could you use Firebug with OpenLayers to check the TinyOWS output stream ?

Hi,
Did you mention what version you were using? Perhaps it is version 0.9.0 which was indeed using keywords "prefix" and "server". Change into ns_prefix adn ns_uri was done last spring http://tinyows.org/trac/changeset/343
If that is the case I would recommend updating your TinyOWS to the current release canditate.

Content-Type: text/plain; charset="us-ascii"
Hi,
I am trying to use gml_[item name]_alias for renaming my columns in wfs GetFeature request with gml output. Everything works fine except I can't use some characters like whitespace for example, because it is not a valid xml element.
My question is - is there any way to name my attribute like "my attribute" through WFS GetFeature request?
Btw, I am presenting the result in a html table, so would be useful, for example, to be able to handle this and other stuff like type for example (integer, string, ..) through the mapfile. And maybe to use this on the client to align data in a table (numbers right, string left, etc.)
Thanks very much on any useful info
regards, dejan

There were some changes to string quoting/escaping in version 6 (I think).
Are the errors you are seeing intermittent, or is it reproducible
consistently on all requests?
What happens if you use
CONNECTION "dbname=interlocken user=interlocken ..."
instead of
CONNECTION "dbname='interlocken' user='interlocken' ..."

Everything is show ok on the map but the symbol in the legend is very big, and exceeds the symbol key box very much, although KEYSIZE is set to 25 18.

Hi,
This should be simple to test and verify.
Write into WEB METADATA parameters
"wms_title" "test_?"
"wfs_title" "test_?"
WMS 1.1.1 GetGapabilities does not have any trouble with "?" and request sends back
...
<Service>
<Name>OGC:WMS</Name>
<Title>test_?</Title>
....
However, WFS GetCapabilities response gets truncated. All that Mapserver sends is this
<?xml version="1.0" encoding="ISO-8859-1"?>
<wfs:WFS_Capabilities xmlns:gml="http://www.opengis.net/gml" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ows="http://www.opengis.net/ows" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ogc="http://www.opengis.net/ogc" xmlns="http://www.opengis.net/wfs" version="1.1.0" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">

<ows:Title>test_
The same error occurs if non-ascii characters are used in "wfs_abstract".
I was testing on Windows and Mapserver 6.0.1.
