[mapserver-users] Not transforming polygons to points

[Oliver Wesp]

Dear List,

I have some datasets where the data is organized in layers containing
both points and polygons. I read these datasets through ogr. I need to
integrate these datasets as two different layers into my mapfile. One
time to display just the polygons (works fine) and another to display
the points. Unfortunately mapserver transforms the polygons to points
so every node is shown. Is there any way to prevent this
transformation and to display only the features that are actually
points?

best regards,
Oliver

[mapserver-users] Re: [UMN_MAPSERVER-USERS] Problem: ANGLEITEM and TRANSPARENT

[Oliver Wesp]

Dear List,

I'm facing the same problems adressed in the messages below regarding
the transpareny of pixmap symbols. Pixmap symbols lose their
transparency after rotation or resizing with ANGLE
 or SIZE parameter. I'm working with mapserver 5.4.0 and gd 2.0.32. Is
anybody aware of this problem? Was this fixed with later versions of
GD? Any help is appreciated.

best regards,
Oliver

Re: [mapserver-users] msOGRFileNextShape(): OGR error. TopologyException: side location conflict

[Oliver Wesp]

Hi,

we recently struggled with exactely the same kind of errors
(TopologyException) when reading S57 data through ogr. We discovered
that the problem only occured when gdal/ogr was build against GEOS. We
rebuild without GEOS support and the TopologyExceptions dissapeard.

Best regards,
Oliver

Re: [mapserver-users] [Info] S-57 nautical map on MapServer

[Oliver Wesp]

We did similar work for IENC Data (inland water)  in Germany. Have a look at

http://wsvmapserv.wsv.bund.de/wms_ienc?REQUEST=GetCapabilities&SERVICE=WMS&VERSION=1.1.1

We're reading S-57 .000 files direct through the OGR Library as Jeff
suggested. We also used scripts for generating tile indexes the way we
needed them and for generating symbols from the S-52 Standard. Also we
used a php wrapper script for generating a S-52 like pick report on
GetFeatureInfo.

Feel free to contact me if you like more details.

Best regards,
Oliver

Re: [mapserver-users] Re: Mapfile multiple CLASSITEM's

[Oliver Wesp]

Hi,
It's not possible to use more than one field in CLASSITEM but it's is
indeed possible to use more than one field in your expression, so you
don't need CLASSITEM at all.

Say you have to fields ANIMAL and ANIMALSIZE.

CLASS
 NAME "SMALL PIG"
 EXPRESSION ([ANIMAL] = 'PIG' AND [ANIMALSIZE] = "SMALL")
 STYLE
   ANGLE 360
   COLOR 0 0 0
   OUTLINECOLOR 0 0 0
   SIZE 10
   SYMBOL "YourPointSymbol"
   WIDTH 1
 END
END
CLASS
 NAME "BIG PIG"
 EXPRESSION ([ANIMAL] = 'PIG' AND [ANIMALSIZE] = "BIG")
 STYLE
   ANGLE 360
   COLOR 0 0 0
   OUTLINECOLOR 100 100 100
   SIZE 10
   SYMBOL "YourPointSymbol"
   WIDTH 1
 END
  END

You still need more than one class but it does the trick.

Best regards,
Oliver

[mapserver-users] WMS GetFeatureInfo returning no results with 5.6

[Oliver Wesp]

Dear List,

I'm trying to execute a GetFeatureInfo Request to an S57-File via OGR.
The Request works fine in 5.2.0 returning all the attributes.
Trying the same request and the same mapfile with Mapserver 5.6.1 or
5.6.5 I just get "Search returned no results.".

Did I miss some configuration changes from 5.2 to 5.6 or is something
else going wrong?

All this happens on a Windows Server 2003 Box.

Below is the mapfile.

Any help ist appreciated.

best regards,
Oliver

[Oliver Wesp]

Found out that it works as soon as I define a TOLERANCE of at least 1
Pixel for the Layer. Thats fine for me also I don't know if that is
intended.

[mapserver-users] Mapserver crashes with large number of layers

[Oliver Wesp]

Dear List,

we're kind of stuck with the following problem:

First of all we are running Mapserver 5.6.5 in CGI Mode on Windows
2003 Server (64bit). Webserver is Apache 2.2.

We have a large Mapfile (seperated into 5 different parts using
INCLUDE) with a total of 571 Layers. The layers have different
MAXSCALEDENOM values  so not all of them are drawn at all scales. The
layers are referencing the DATA via TILEINDEX (it's S-57 data read
through OGR). Most of the layers cover only a small area, so if I zoom
in to the map more and more layers must be taken into account of
drawing but only a small number must be drawn. All of the layers are
divided into three groups using the GROUP parameter.
What happens if I zoom in to the map at some point mapserver crashes
(actually it's not crashing it just stucks). If I reduce the total
number of layers (by commenting out parts of the mapfile) the map will
be drawn again. So my guess is that there is a problem with the number
of layers (or styles?, or symbols?, or number of layers per group?)
included.
I turned on debugging on all of my layers but that didn't helped. If I
check the taskmanager mapserver.exe goes to 100% cpu usage and goes
back to zero after a few seconds but it's not being terminated. It's
still running in the process list. Debug output stops right in the
middle of the line. No error message is send to the client or written
to any of the logfiles. Actually no response is send to the client at
all. If I terminate the process using the task manager "Premature end
of script headers: mapserv.exe" is written to the apache error.log and
the client shows "Internal Server Error".

Right know we have no idea of what to look at. If anybody has any hint
what might goes wrong we maybe would be able to look at it and maybe
fix it. But right now we're stuck.

Best regards,
Oliver

Re: [mapserver-users] Mapserver crashes with large number of layers

[Oliver Wesp]

Hello,

thanks for your help. Like you recommended I tried the request through
the commandline hoping for some kind of new error messages. Instead
the request just did what it should und returned the png without any
error. So it  works through commandline and crashes through cgi.

I also made a test on a 32bit machine and it shows the same behaviour.
And indeed we build mapserver by ourself but we can replicate the
problem with the binary from MS4W.

Best regards,
Oliver

Re: [mapserver-users] Mapserver crashes with large number of layers

[Oliver Wesp]

Thanks anyone for the help.

We didn't actually solved the problem but we found out how to avoid
it. First thing we found out was that the map was succesfully drawn
and that mapserver stucks after that. I tried it with mapscript and
the map image gets written to disk and after that php cgi stucks the
same way mapserver cgi does before. We didn't find out what exactly
happens but it's seems mapserver stucks when writing to the log files.
When we did some try and error with the logging mechanism we found out
(by accident) that everything is fine as soon as we turn of debugging
in the mapfile. For the moment I'm fine with this workaround but I
will try to get a small demo together as soon as as possible so maybe
somebody can have a look at it.

Best regards ,
Oliver

[mapserver-users] Segmentation Fault on Solaris parsing Template

[Oliver Wesp]

Dear List,

I had a running installation of mapserver 4.8.1 on a solaris box which
suddenly stopped working. I'm using mapserver as cgi and everything
was fine until suddenly mapserver crashes with a segmentation fault. I
made a few tests and what it comes down to is that mapserver crashes
parsing the template in mode=browse. If I make a request with mode=map
everything is fine. With mode=browse mapserver generate the images,
returns the template just before the line where the first variable
substitution appears and crashes. Here is some more information from
the core dump:

gdb mapserv_481 core

#0  0xfe633218 in strlen () from /usr/lib/libc.so.1
#1  0xfe686530 in _doprnt () from /usr/lib/libc.so.1
#2  0xfe6882d8 in snprintf () from /usr/lib/libc.so.1
#3  0x00029cbc in processLine (msObj=0xecb48, instr=0xffbe9a30
"/tmp/map_sb120895549616000.png", mode=0) at maptemplate.c:2384
#4  0x0002c26c in msReturnURL (msObj=0xecb48, url=0x1023a0
"..//html/error.html", mode=0) at maptemplate.c:2918
#5  0x0001f244 in writeError () at mapserv.c:200
#6  0x00023bf8 in main (argc=2, argv=0xffbeb5a4) at mapserv.c:1276

I don't have direct access to the machine but there have been some
software installation and I don't now if some libs have changed. Maybe
someone can give me some hints...

best regards,
Oliver

[mapserver-users] Build Mapserver 5.0.2 with sde support on solaris 5.8

Dear List,

I'm trying to build mapserver 5.0.2 with support for sde 9.2 on my
solaris 5.8 box. The following problem occurs:

ld: fatal: Symbol referencing errors. No output written to shp2img
collect2: ld returned 1 exit status

I guess the missing references are in libCrun.so.1 so I tried to add
"-L/usr/lib -lCrun" but that gives me "libCrun not found" but
libCrun.so.1 is located in /usr/lib.

Any ideas?

I'm trying to build with gcc 3.2.3.

best regards,
Oliver
