[mapserver-users] tracking the origin of errors
Help! I see a variety of messages in my mapserver log file with debug off. Some, like these, prompt me to ask what parameters were used when the error condition occurred: msProcessProjection(): Projection library error. projection not named msProjectRect(): some points failed to reproject, doing internal sampling. But despite changing debug to 5, I don't see any information in the log that would indicate what the input was. I use mapserv exclusively to provide OGC WMS and WFS, so it would help to have the URL for the requests in which there was an error. Is there any way to get mapserv to provide this information?

[mapserver-users] EXCEPTIONS format question
Help! Seeing some errors in my mapserv.log file, I edited all of my map files to add, in the metadata section of each layer, the single item wms_exceptions_format application/vnd.ogc.se_xml Now I see a few errors that say WMS server error. Invalid format application/vnd.ogc.se_XML for the EXCEPTIONS parameter. It would seem that the wms_exceptions_format value is case sensitive; should it be? Is this metadata item repeatable? Can I write, for example wms_exceptions_format application/vnd.ogc.se_xml wms_exceptions_format application/vnd.ogc.se_XML or perhaps wms_exceptions_format application/vnd.ogc.se_xml, appplication/vnd.ogc.se_XML Peter -- Peter N.

Re: [mapserver-users] minscaledenom puzzle, Mapserver 6.0.1
Thanks Thomas and Steve!
Thomas is right that I needed a real symbol and not symbol 0
within the pixel-sized class. I was confused by the docs under
class:symbol, which says Default is 0, which results in a single
pixel, ... Is that part now out of date?
But I like Steve's suggestion that using two layer definitions and
setting the scale denominator for the entire layer in each case
might save time that mapserver would have spent deciding how to draw
each point's symbol.
Of course the most important optimization I can make is the one that
I have not yet learned to implement--tiling. But I want to get the
basics done as well as I can first.
I appreciate being pointed to group--this is something I had not
learned about before, perhaps because I had not seen its practical use
until now. Works very nicely.
I don't know how to answer the question what renderer are you using
beyond doing mapserv -v; its output is
MapServer version 6.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML
SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=CAIRO SUPPORTS=FREETYPE SUPPORTS=ICONV
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WCS_SERVER
SUPPORTS=SOS_SERVER SUPPORTS=GEOS INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE
and in my openlayers code that calls this layer I'm not specifying
an image format. So I assume that mapserv is falling into a default
that is based on my compilation options. Based on the docs, it looks
like I'm defaulting to AGG for png images (which my openlayers is
requesting by default).
My map now (at version 6) appears fuzzier than it did at version 5.
Perhaps this renderer does more anti-aliasing?
Anyway thanks for your help. I will continue to explore.

Hmmm... What if you use one layer with the various class/expressions
and MAXSCALEDENOM set at the layer level for
all the various squares and then a second layer with just one class
for the pixels with MINSCALEDENOM set. I typically
use layer scales far more than class scale and that setup would
perform much better than what you have since there would
be no expressions or scale computations in the scale 700 case. E.g.:
LAYER
NAME 'sites_high'
GROUP 'sites'
MAXSCALE 700
...multi-class...
END
LAYER
NAME 'sites_low'
GROUP 'sites'
MINSCALE 700
...one class...
END
If the second layer indeed renders then it's a class handling issue.
If the second layer (with pixels) doesn't render then
it's a drawing issue. What backend is used, GD or AGG?

But under 6.0.1, I am not getting the 1-pixel symbols when zoomed out.
I assumed that the last class defined above would apply when the scale
is coarser than 1:7M.
Here is the OpenLayers command that loads this layer:
var wms = new OpenLayers.Layer.WMS(

{
map: 'mrds.map',

Would some modification of my map file or my OpenLayers javascript
bring back my little red pixels?
Thanks for any help you might offer.

[mapserver-users] Seeking guidance for gml_geometries in WFS config
I'm running Mapserver 5.4.1, drawing data from PostGIS/PostgreSQL, using WMS successfully with OpenLayers. I have tried to configure the same data as WFS, and am trying to debug using uDig. Through helpful advice from the udig-users list, I now question my use of the gml_geometries and gml_[name]_type elements of the map file. The WFS server how-to page mentions these elements and describes how to write them but doesn't give strong guidance as to why one would, or what the right sort of values should be. So I ask here. My WFS services are currently described at http://mrdata.usgs.gov/wfs.html The map file for active mines, a point data set, contains the code below.
