I tried to answer this mail ..

apologize me if it will be a bit confused and for any my mistake.

i'm newbie in live-dvd preparation so maybe is possible i'm ignoring something
but i hope you can point me on the right direction to follow.

Maning, Massimo, Alex, Ravi,

Thank you all for your kinds offers of help with the LiveDVD. This is greatly appreciated, will be very valuable, and will also make space for the overly committed FOSS4G local organising committee to focus on the other aspects of the FOSS4G conference.

As I see it, this is what needs to be done:
1. Anyone who is interested, please subscribe to the live-dvd email list, where we can continue the rest of this discussion. http://lists.osgeo.org/mailman/listinfo/live-demo

i'm already subscribed to the list,
i read the previouse topic and i agree that the main distro to be used must be a debian/debian-based distro.

as live-builder system, i'm tring the remastersys tool
i find it really complete and works fine on ubuntu and debian but need to be hacked to works on sidux. (the best solution for me is to have a custom script to produce a live.iso from an installed linux-distro based on sidux, i prefer to chose sidux beacouse it has updated packages (it include the debian- gis repository, and beacouse has an updated kernel and some virtualizzation .. is the only distro that works fine on my HW "macbook pro 15'' 2,2 with ati 1600 video card))

The wiki associated with this project is at:

i tried to describe the procedure i'm using to build some gis SW on sidux installing the svn version on the osgeo wiki page (search for gfoss.it in the search tool)

I agree with you that for a live projet we need to use the debian-gis

however i prefer to have the last version installed from source. (at least for the main app osgeo project)

why? :

building from source we'll have all the dev-package installed in the live

this implies that a live-dvd user can choose to install the live on its hard-drive (install option is handled by remastersys) and having all the dependencies already installed will simplify the life to an user that want update to the latest version for the source- installed gis app

(this will guarantee a long life for the live ptroject and avoid intense dependence from repository)

obviously is not my intent to build all from source, but only the main osgeo project like :
Gdal, Grass, Ossim, Qgis, ...+?

2. We need someone who can continually keep track of the status of the LiveDVD. Determine what it contains, what package versions are on it, how much space is being used, what should and should not be on it etc.
This data should be kept up to date in this wiki:

i done a list of apt-get-able packages related to scientiphic and geographics software, icluding python dependencies for qgis plug-in R package to handle spatial data, other sw more or less related to academic/sciantific world

2b. Revise the LiveDVD schedule, and then track to it.

3. The LiveDVD needs to be tested, and make sure that the current, and any future packages all work together without impacting each other. Any issues found need to be tracked in the issue tracker.

4. Someone needs to contact all interested parties for the LiveDVD, and encourage them to provide data or software, or configurations, etc for the LiveDVD. This includes: * Workshop and tutorial authors who may want to hand out a DVD at the conference.
* OSGeo projects already on the LiveDVD, or who want to get on the DVD
* UbuntuGIS, DebianGIS, GISVM, OSGeo4W packaging projects, which have significant synergies with the LiveDVD
* And any other people who want to help out.

tring variouse live-dvd build i had some different problems on different distro :

ubuntu 9.04 :

problem to build ossim (mailed the dev list about my issue)
some problems with pyQwt (use python 2.5 while the python used as default is 2.6)

debian+ubuntu :

kernel minor than 2.6.30 has proble to get a working driver on mac laptop using ati video card. again on generic hardware i need to manually install the video driver to enable a full 3d environment

Sidux :

the driver installed as default works well on mac laptop and the 3d environment work out of box on different hardware
whitout need to install additional drivers
but the problem is :

using remastersys (script dedicated to debian and ubuntu distro) i need to hack the script to figure out a kernel module problems : remastersys try to find a pakage "squashfs-module" that on sidux is included in the kernel .. so remastersys fail to check the module presence (but it exists) to figure out this problem i commented out the relative "if statment" to check the module presence.
after this littlle hack i have remastersys "semi-working" on sidux too.
the live-dvd produced has a working gis software (also 3d with ossimplanet) but unluky the script fails to configure the network (resolvconf problems)
and it has missed the "install to hd" tools.
(i'm subsribed to the remastersys forum and i'm tring to get support about this problem)

in short word :

using debian or ubuntu i'm not able to have a really platform independent 3d environment but i have an installable live-dvd

while on sidux i have all working in live-mode except to the resolvconf-dhcp problem (i'll meet a server-mantainers in the next days to face out this problem)

again the live is not yet installable on HD (i'm tring to solve this on the remastersys forum).

5. Add what ever new packages, linux software, windows installers, etc to the LiveDVD. This is the technical grunt work. Note that the packaging projects like DebianGIS and UbuntuGIS are quite robust, and have been very helpful in getting new people started with packaging, and many of these people are also on the LiveDVD email list.

i've discuss about the osgeo live-dvd project on our local-chapter list, we'll be avaiable to produce a local dataset and localized documents.

my idea is to use as example data a common dataset based on global data + a localized dataset based on local-free data if avaiable. however we need a common tutorial/how-to workshop files to follow as guide-line for the local chapters.

just a littel consideration maybe is is obviouse,
i'm tring the variouse .iso produced and is my idea that the live.iso works really more fast if it is booted in a virtualbox machine i do some test on the live.iso, i find that running it in a VirtualBox Machine, it is really fast rather than a boot from cd.

thanks to read this long-confuse mail and for any feedback.


Welcome aboard.
I suggest that any volunteers join the live-demo email list, and respond to this email suggesting how you might want to help.

Happy to note a good discussion.
I can help in seeing the draft of workshops/Labs that deal with Vector-GIS and GIS that focuses on Geoscience. Can help in advising where necessary, to tune the material such that those multitudes not attending the event can equally use the material with ease.

Hi All,

I'm  working on a live dvd project based on GIS

i'm avaiable for any help on the dvd creation.

let me know.

Hi Ravi,

Yes, you are so right, we do need to collect as much of the
material from the FOSS4G conference as we can.

One way we hope to facilitate this has been to give every
attendee a LiveDVD which can be populated with all the
material from the workshops. This means that if workshop
presenters can get their data onto the DVD, then they know
all attendees will receive it.

So we have budget for the LiveDVD. We have an old version
of the LiveDVD (based on FOSS4G 2008). What we need to
continue through to completion is to have someone who will
coordinate the compiling of the DVD.  This is primarily a
project management role, keeping track of what is on the DVD
and what should be on it, contacting workshop authors, and
project leads and helping them get their projects onto the
DVD etc.

Sound like you? It would be an incredibly valuable
contribution to FOSS4G and the greater OSGeo community at

Hi All,

FOSS4G every year is a keenly followed event. Many await
the publication of material on the website eagerly such that
they can follow labs, workshops and presentations of

So the present organisers may please request those
especially conducting labs/workshops to keep in mind the
multitudes who browse them through the internet can have
equal benefit. This can be achieved my keeping on the
internet for download

1. All the binaries that are required for the exercise

2. All the data that are required for the exercise

3. All the printed material provided for the exercise

4. All the other material provided to the attendees, CD or
DVD etc

I agree that most of it is done each time, except for a few

Example:'Download data from the CD provided', is
given in the lab pdf.. but the data is not given for

Example:'Run the pg_setenv.bat file first,'
(FOSS4G2007).. even on date a nice archive is available from
the FOSS4G2007 website, data, text etc..

but, the pg_setenv.bat, not there.

This may be trivial for experts, but for those learning
through the internet and depending on 'Discuss
Lists', it will be a roadblock.

I think Massimo is right, there are lots of people who can
not attend FOSSG4, but would like to learn
through Internet the workshops and conferences. As it is a
fast growing field, the sooner the better. Please,

if there is a way to help this happen, let me know!

I am from Mexico, so if there is some need for spanish
translation, or any other work I'll be glad to help.
