Re: [Qgis-user] How to display SID raster on QGIS 2.10 PISA Kubuntu 15.04 ?
Last night at a cugos.org meeting, I learned how to compile GDAL with MrSID capabilities. The system he used as a chromebook. You can find the instructions in the link below. I believe that QGIS uses your system's GDAL installation for most of its operations. https://dl.dropboxusercontent.com/u/26575408/gdal_mrsid/gdal_mrsid.html On Thu, Aug 20, 2015 at 8:41 AM, Joachim Bergerhoff agi...@gmail.com wrote: Dears, I guess the message title is explicit enough ?

The instructions can be found somewhere in the qgis-maze, but I don't how up-to-date they are. I tried once, but as the instructions were not really idiot-proof and I prefer to use repositories, and as there was no clear instruction to be found how to deal with incompatibilities, I gave up so far. I think the masterbrains just compile everything, and the stupid masses use a virtual Windows machine to transform to geoTIFF (like me).

If you want to you can download the MrSid SDK and uncompress the sids on your linux workstation: http://www.lizardtech.com/downloads/category/ (MrSID SDK) I downloaded the SDK (placed it in /home/rjhale/apps and wrote a very small messy script that does the following: #!/bin/bash #set library path export LD_LIBRARY_PATH=/home/rjhale/apps/sidgeodecode/bin #fix the extension file=$1 newname=`echo $file | sed 's/\(.*\.\)sid/\1tif/'` #run the Geodecode program /home/rjhale/apps/sidgeodecode/bin/mrsidgeodecode -wf -i $file -o $newname It usually takes just a minute or two to uncompress them on my workstation - for me a sid that is 400 mb usually uncompresses to 6 GB - with a small amount of work (tiling, pyramid layers) it's renders very nicely. I agree - building sid support into QGIS is not for the faint of heart. I did it once but decided against - I would rather just uncompress them using this route and be done with it.
