[Geomoose-users] Re: printing in geomoose

     If you read the doc at http://www.gdal.org/frmt_wms.html you will 
see that it is possible to enable cache using <cache> block in your GDAL 
WMS XML.  If you are using my OSM_TAH.map/.xml as a guide, this will 
cache the image tiles created/stored by OpenStreetMap and requested by 
your server via mapserver/gdal.  You are basically using mapserver as a 
TMS client and having it render the tiles into one image to send to the 
browser.  This approach works well for aerial/satellite imagery server 
up in tiles, but not very well for "street" maps because the image tiles 
are resampled as they are written into the output image.  This can lead 
to unreadable text labels and other resampling artifacts, but it is 
quick to set up.

     The approach given at 
http://trac.osgeo.org/mapserver/wiki/RenderingOsmDataUbuntu is totally 
different.  It describes how to get the original VECTOR data (not the 
rendered image tiles) from OpenStreetMap and render it yourself on your 
server.  I think this a superior approach since it doesn't rely on the 
OSM server performance (and you can create your own rendering styles), 
but takes a lot more effort to set up.

     Perhaps some of the other GeoMoose (or mapserver?) users would have 
more info on setting up mapcache...

But now I don't know why is the error occuring, because I haven't changed print_util.php before. And when I tried to comment that line with IMAGETYPE=print in print_util.php it throws exactly same errors as I experience when trying to print layers from geoserver. You can see them here: http://osgeo-org.1560.n6.nabble.com/printing-in-geomoose-td4684481.html In that time I thought there is problem in comunication between geomoose and geoserver, but now, when I commented that line out, it is the same with the mapserver. So, maybe I just need to solve this problem and I will be at good point.

>> Couple of months ago, you sent me some files to use for printing the OSM tiles. Many thanks again. Since that time I was coping another projects and stuff. Now I got back to it. As you, probably, remember I had a problem with printing in geomoose using geoserver. It still is there, but now I tried a new approach, I set up mapserver and make it work. It looks like it is okey now.

>> I have also tried this manual http://trac.osgeo.org/mapserver/wiki/RenderingOsmDataUbuntu . It throws the same errors each time I try to print the layer and the PDF, jpeg and html files are all blank. I can see these layers when I turn them on in geomoose, but when I print them these errors occur.
>> And I have another (probably) stupid question. When I am using anyone of these two layers and I am moving the view or zoom level, they are acting weird, because when I zoom, usually I can see just a piece of zoomed area, or when I move the map to whichever side it usually return back where it was before moving or move  in the other direction...

I have hardly ever used a map file, so what you are suggesting here ( http://www.osgeo.org/pipermail/geomoose-users/2010-July/002435.html ) is a little bit problematic for me. I tried to write a map file with layer of openstreetmap tiles. I wanted to use it as a base layer with possibility to print. But i wasn't successful.
