Re: [Qgis-user] What can you do with the Python console?

[Qgis-user] QGIS and ECW and MrSid formats
Hi! Could we clarify the situation for ecw and Mrsid formats in QGIS? (and perhaps put a note somewhere in the qgis web pages). I think that not being able to read these formats is a major drawback in practice. At least in Spain, a lot of public available raster layers are in these formats. Also, for example, the imagery at https://zulu.ssc.nasa.gov/mrsid/ (I know the original landsat images for those are available in not compressed formats, but that site is very convenient for many people) If there is a compiled version of gdal including support for these formats, why QGIS cannot? In any case, is there any workaround so that users can get to have ecw/Mrsid support out of their compiled version? Perhaps through a plugin? I really think that the final QGIS1.0 should be able to read in those formats, somehow. This is probably seen as a minor concern for developers, but a significant problem for users.

Last time we exchanged our frustration with this situation, I even gave a name to the new gdal binaries: we need a gdal-good gdal-bad and gdal-ugly in the same fashion that licence encumbered audio codecs are released as binaries outside of the standard distro repositories.

Your suggestion of a "default_project.qgs" should fill the bill. And it opens the way for adding other global project definitions it the future. Yes, I've implemented it at mine by launching the project file at startup and it's really comfortable. However it's only a workaround... I still wonder if Global Default Projection shouldn't be used also for project projection. In my opinion, yes... Regards!

The situation is, unfortunately, clear: The QGIS project can't allow itself to distribute software with support for formats which they themselves can not be further distributed. And that seems to be the case with ecw. I think that things are not really that bad. Today I've took a brief look at the licenses for ECW and MrSid and it seems that it's okay to build and distribute qgis with their pieces of software if we distribute only the binaries (i.e. not their SDKs). They additionaly request to add their copyright text to about box / readme. MrSid SDK allows only decoding, ECW also encoding, but only up to 500mb. And I think they also require that user accepts their EULA before using those formats. If there is a compiled version of gdal including support for these formats, why QGIS cannot?

While I'm not a developer, the with my (very) little understanding of how QGIS and gdal interact, I don't think this is possible with a plugin. For all work with raster data (except WMS) we use GDAL. So, support for ecw/mrsid must be compiled against gdal. I really think that the final QGIS1.0 should be able to read in those formats, somehow.

From what I've written above, I think everything is just a matter of packaging (and some more annoyances with license statements and copyright notices). - for windows we create the whole toolchain by ourselves so including these formats in GDAL is a matter of compiling GDAL with appropriate SDKs - for linux the situation is more complicated. users usually use gdal packages from their distribution, so we would need to produce alternative packages for several distributions which would be compatible with original ones.

There are no configure scripts for ECW and MrSID but it should be possible to copy and modify the GRASS plugin build script. William must have either done this or written his own build routine since he has created working Mac GDAL plugins. Yes, I originally started with a configured GRASS plugin makefile to create makefiles for other plugins. They're almost unrecognizable now, and are tailored to compiling for the OSX framework (universal, framework-only, no configure step), but could be easily extended to support other systems. Generally, get the OBJ list from the driver's GNUmakefile, and discover the CFLAGS and LDFLAGS (include paths and external libraries) needed for the format for your system by running configure as if you wanted to build the formats into GDAL (values will be in gdalmake.opt). Someone who knows autotools (or cmake) could make configurable standalone source packages like the GRASS plugin. - William Kyngesburye kyngchaos*at*kyngchaos*dot*com http://www.kyngchaos.com/ Mon Dieu! but they are all alike.
