Re: [mapserver-users] geotiff 48bit with mapserver 7 wms
Hi Benjamin, thank you for your tip. QGIS renders the tiles if a set min/max and "stretch to min/max". I did the test with a smaller data set (200 tiles 130MB each). My problem now is, with all tiles (~18500) the connection times out, even with small bounding boxes like: http://192.168.3.231/?MAP=/maps/MAP/eowcs2.map&=WCS=1.0.0=GetCoverage=GEOTIFF=test=646021,5524001,648018,5525998=EPSG:32718_CRS=EPSG:32718=4000=4000 (QGIS always uses the full extent as bbox for the query and times out. Even zoomed in. *sick*) The same data set as WMS, with MINSCALEDENOM MAXSCALEDENOM runs very smooth. I did not find very much help regarding performance improvements and mapserver. For WMS you find alot.

Re: [mapserver-users] geotiff 48bit with mapserver 7 wms
Dear David, Steve, Ben, etc. I am working with MapServer-WCS. I still have problems defining the correct output formats. Input to most of our WCS are 8bit Geotiffs. The MapServer WCS-output is either tiff, png or jpeg with 24bit or Png;mode=8bit with 8 bit (if no output format is defined). The png;mode=8bit-format changes the imagecolours, so it isn't really useful. I can't get a colored 8bit Geotiff as output (a 8bit-definition always results in greyscale images). I tried different output format-definitions, none of them worked. I can define a palette for the png-format, but unfortunately not for any other format. For our WCS it is important that the output-data looks the same like the input-data. It seems that at the moment MapServer can't just pass the input-data through... This might be a GDAL issue... So if you find a way to define your wished output-format, please share it, maybe it helps me, too. Maybe anybody else has an idea?
