The ability to put Thuban on a media an run it from there is independent from the "install_local" feature. This feature is only a comfort function to copy the Thuban files to the system location where it usually would reside in a GNU/Linux system. "install_local" allows you to run Thuban directly in place. Of course you can produce a self-contain media running Thuban. (My company Intevation has done this a few years ago.) You need to put everything on that you need to run Thuban. There are two general ways: a) Complete operating system and Thuban. Works e.g. GNU/Linux like a kanotix or morphix live-CDs. Needs all Thuban packages installed. Putting it in will boot it. b) Only the Thuban application (with all dependencies) e.g. ready to run for several operating system like Windows, GNU/Linux. > What I am looking for is a "portable" (in the sense of moving arround) > GIS viewer that I can use to deliver results of my work to reviewers, > collegues or clients who are not GIS specialists, who may not have GIS > systems installed or just want to view the results of the work.

I do not have experience with portablepython, so I can only guess. My guess is that you at least need the wxWidget and other binary libraries, but you can make it work. I cannot say how difficult it is, though, without having tried myself. > Would a Thuban installation configured in such a way run from any PC > (Linux or Windows) without problems or further dependencies? GNU/Linux and Windows would need binary libraries for their specific variants (e.g. Debian Etch, Ubuntu, RedHat, XP, Vista). Thuban needs those libraries and they are not pure python. > Can I then specify a defaukt session in my startup script that > automatically starts the programm with my layers? Yes. > P.S.: I put this mailing list up on Gmane. I hope that you like that... I am not using Gmame myself, I have nothing against spreading knowledge about this public list. :) Best, Bernhard -- Managing Director - Owner: www.intevation.net (Free Software Company) Germany Coordinator: fsfeurope.org.
