 Note that for Mapserver (rather, OGR) to USE the qix file, you must not  
 specify the .shp extension in your DATA statement. If you do, the qix  
 will simply be skipped. e.g.
DATA data/streets/streets.shp
 should be:
DATA data/streets/streets
 (someone correct me if this has changed)

I just verified this on Mapserver 5.0.0 (the on in current Ubuntu). It
tries to open data/streets/streets.shp.qix instead of
data/streets/streets.gix.

But it looks like it has already been fixed in newer versions:

[mapserver-users] 5.2 Problems

2008-08-12 Thread Derek Bain

Hi Jukka

This is what i get back. I should be using WMS. I have defined WMS as the 
connectiontype in the map file. All worked okay on the previous version of 
ms4w. I also tried using shp2img on my map file and it returned saying that i 
need to define WEB.IMAGEPATH in my map file which i did not need in the 
previous version. I added this and the image file generated has 

msWMSLoadGetMapParams(): WMS Server Error.  Invalid layer(s) given in the 
LAYERS parameter

As I say all worked previously. Here is my mapserv -v output if it helps anyone

C:\ms4wmapserv -v

Re: [mapserver-users] Memoryproblem

2008-08-12 Thread Tamas Szekeres

Johan,

I haven't run into this problem yet. Do you able to run the getbytes
console application in the /csharp directory?
Is this issue deterministic or random? Do you have an example to reproduce it?

Best regards,

Tamas

 Hello



 I have a major problem when using imgMapObj.getBytes().

 The memory will be corrupt. The problem doesn't occur when using the save
 function.  I have not seen the problem on other servers so the problem seams
 to be related to a specific server (Windows Server 2003 standard edition).

RE: [mapserver-users] Connection to Mysql 5.0

2008-08-12 Thread Fawcett, David

Nikos, 

Is it possible that MapServer is using a different ogr binary than the
one that you are hitting from the command line.  This is really a
question for the MS4W people and not you, I guess.  

One possible reason that you are having this problem would be if
MapServer was compiled with a different ogr than the one that you are
hitting with your commandline and the one that MapServer is using wasn't
compiled with MySQL support.  

I am guessing that the MS4W maintainers could prove or destroy this
theory pretty quickly...

David.

Hello to everyone!

i have a problem in implementing the example i found in 
http://mapserver.gis.umn.edu/docs/howto/ogrmysql.
I want to project some points on the map.
I have created the .ovf file and the database i want to access with some

appropriate data.
I have also created a user and granted it with all privileges. (GRANT
ALL ON 'dbase_name'.* to 'user'@localhost identified by 'password');

When i use command prompt to connect to mysql with ogrinfo.exe 
everything goes fine!
(ogrinfo.exe -al 
MYSQL:my_db,user='user',password='password',host=localhost,port=3306,tab
les=points;).
The results i get are information about the table contained in database 
and the contents of the selected table.

Next i run  ogrinfo.exe -al /path/to/ovf_file.ovf   and again i get the 
result i expected..
(except from the warning
ERROR 4: Update access not supported fow VRT datasources
Had to open data source in read-only which is fine according to the 
example!).

But when i use the .ovf file through the .map file ,and after a few 
seconds,i get the message :


  /Internal Server Error/

/The server encountered an internal error or misconfiguration and was 
unable to complete your request./

/Please contact the server administrator, [EMAIL PROTECTED] and inform 
them of the time the error occurred, and anything you might have done 
that may have caused the error./

/More information about this error may be available in the server error 
log./


Can anyone help me becuse i'm stuck with this.
Is it preferable to access mysql with php\mapscript instead?

And if yes,is there any informative tutorial???

Thank you in advance!

Well. The ogrinfo i am using is installed with mapserver 
(ms4w-2.2.7-setup.exe).

and the ogrinfo.exe is in C:\ms4w\tools\gdal-ogr.
So i guess that mapserver is using the same binary...

Anyway,i hope i get an answer !!!
Thank you.

2008-08-12 Thread Yvan Calcagni


Thanks David, but I tried this and it didn't work. Nevertheless I found a way 
to solve my problem. I'm pretty sure this solution isn't very clean but it 
works. So, I replaced the EPSG:27582 lon_0 parameter (previously set to 0) with 
this one : +lon_0=2.33722917 and I don't know why but it worked...

See you.

[MAPSERVER-USERS] ms4w bug: mapserv returns empty(blank) image

2008-08-12 Thread BrainDrain


I have this input projection for my layers
+proj=tmerc +lat_0=0 +lon_0=45 +k=1.00 +x_0=0 +y_0=0 +ellps=krass
+towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=mm +no_defs (local coordsys)
and this is output proj
+proj=tmerc +lat_0=0 +lon_0=45 +k=1.00 +x_0=0 +y_0=0 +ellps=krass
+towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=m +no_defs (just mm-m)
so I have a 0 0 point in my map  I found holes in some place with certain
zoom scale:
for ex this produces blank image. 
http://localhost/cgi-bin/mapserv.exe?layers=constructmap=C%3A%2FWINDOWS%2FMicrosoft.NET%2FFramework%2Fv2.0.50727%2FTemporary%20ASP.NET%20Files%2Fwem%2Ff47bfcbf%2FSession_mkkoj034s3ocw4ajt4zlfzvp%2F0_cicbase.mapmap_imagetype=AGG_JPEGformat=image%2Fjpegts=1218605020578session=mkkoj034s3ocw4ajt4zlfzvpmode=mapmapext=-81.16385911179067+-11.48545176110251+-0.7656967840724462+68.91271056661571imgext=-81.16385911179067+-11.48545176110251+-0.7656967840724462+68.91271056661571map_size=256+256imgx=128imgy=128imgxy=256+256
I think mapserv will return empty image for such kind of bbox independently
of map file content.

mapscript c# draws normal image for this extent/scale;
map file is correct;
as a solution I can use my own web service to draw map tiles in this
particular cases, but 
now I have changed my output projection to +proj=tmerc +lat_0=48.70975
+lon_0=44.51205 +k=1.00 +x_0=0 +y_0=0 +ellps=krass
+towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=m +no_defs
(normalized to real world) and all works fine)) But this ms4w bug(?) still
exists.

Re: [MAPSERVER-USERS] Memoryproblem

2008-08-12 Thread BrainDrain


I use mapscript c# in my project running in ms win 2003 std/ent r2 and iis6
all works perfect, but some problem related with writing png's exists in
.net (v 2/3.5)

imageObj imgRaw=null;
imgRaw = map.draw();
//this works (without changing image format)
using (MemoryStream ms = new MemoryStream(imgRaw.getBytes()))
ms.WriteTo(response.OutputStream);
//or this (note: the second memory stream,actually, needed only for
iutputing png's!)
imageFormat = ImageFormat.Png;
using (Image img = Image.FromStream(new MemoryStream(imgRaw.getBytes(
{
 using (MemoryStream ms = new MemoryStream())
 {   
  img.Save(ms, imageFormat);
  ms.WriteTo(response.OutputStream);
 }
}
before version 5.2 I had memory corruption problems in some web service
requests (reason - unknown, perhaps it was related with postgis bug - ticket
now closed) during map.draw(), but now all ok. 
+consideration: mapserv.exe (especially in fastcgi mode) much more faster
