[Mapserver-users] Problem with tiled raster data and ms4

[Ed McNierney]

Steffen -

You might try modifying your map file to treat the TILEINDEX shape file
as a POLYGON.  That is, change the layer type to POLYGON and change the
TILEINDEX statement to a DATA statement.  This should display the
outlines of the tiles as polygons.

This will help you determine whether the problem is in accessing the
TILEINDEX file or in the tiled images themselves.

Your problem is almost certainly due, however, to the changes in path
handling between 3.6 and 4.0.  Try rebuilding your TILEINDEX with
absolute paths (I'm guessing they're relative now) and I expect that
will fix the problem.

Subject: [Mapserver-users] Problem with tiled raster data and ms4

Dear list,

I'm using MapServer under win2000 with apache 1.3.27. 

After upgrading from ms 3.6 to 4.0 I have the problem that ms does not
draw tiled raster data anymore. 

When I access a tiled raster layer I get no result from the web server.
In the task manager I see the mapserv-process, but no result will be
delivered to the client. I get no result or error message until I stop
the apache-service.

The same problem I experience when I access the layer using mapscript
(then I see php.exe in the task manager as long as I do not terminate
the apache-service). 

There are no errors logged in the MapServer log and no error messages in
the apache log.

When I use mapserv with my Query included in the "QUERY_STRING="
Parameter I get the correct result - the http-content I expect written
to stdout. When I use shp2img I get the correct image.

When I set the environment variable MS_ERRORFILE in my http.conf
(pointing to some file) it only contains the message "msBuildPath:
Unable to access file." 

When I use apache 2.0.48 anything works fine.

Can anybody give me a hint? Where is my mistake? Does ms4 have a problem
with apache 1.3.x? 

Thanks in advance for your help.
Steffen Bittner
