Re: [gdal-dev] WMS layer issue at higher zoom level

2023-10-20 Thread Rahkonen Jukka via gdal-dev 
Hi,

Do you have another WMS server as a source for this layer? The error message 
that you have this time suggests so: “GDALWMS: Unable to download block 497, 
740.” If that is the case, do you admin also the remote WMS?

If you know the querystring that generated the failure you could run even more 
verbose logging on the command line. Something like:

env CPL_DEBUG=ON CPL_TIMESTAMP=ON MS_DEBUGLEVEL=5 MS_ERRORFILE=/dev/stderr 
mapserv 
QUERY_STRING='SERVICE=WMS=1.3.0=GetMap=image/png=256=256&'

and maybe you could copy the image locally and try something like

gdal_translate -tr 256 256 -projwin ulx uly lrx lry in.tif out.tif

to glean more information.  It's possible the input image (or an overview 
within the image) is corrupted in some way.  If it turns out an overview is 
corrupted, you could try regenerating it with gdaladdo?

Subject: WMS layer issue at higher zoom level

Hi,

I am trying to get a layer from wms and at higher zoom levels I am getting this 
error - msDrawMap(): Image handling error. Failed to draw layer named 
'PICT-INHEND19-psQwiZ1L4t'. drawGDAL(): Unable to access file. 
GDALDatasetRasterIO() failed: /tmp/mapfilePassthru-v2-temp-HxmyxI, band 1: 
IReadBlock failed at X offset 1064, Y offset 1551.

So, for this I checked from the imageservice side the mapfile is being created 
correctly and it is also present there and the mapfile contains a gserve 
request for getting the tiles - that is also working fine. So getting this 
error from mapserver only and tried to put debug level 5 and other things also 
in the mapfile but couldn't get any other error, only this is coming. So need 
help in this if anybody knows what exactly is this and i can i debug mapserver 
locally if i want to then i can figure out the exact point where the error is 
coming from.

Thanks,
Raghav Singh
