Hi,
Natural Earth is a very low resolution dataset.
A lot of OTB algorithms are targeted (and only make sense) for high/very
high resolution imagery.
So it seems very relevant to include some extracts of one or two high
resolution satellite imagery.
My 2 cents...

Hi all,
I answer below to questions about OTB before moving forward:
1. OSGeo-Live is targeted at applications that people can use rather
than libraries that are included into other applications. Does ORFEO
Toolbox have a user interface (possibly command line interface) that a
user can interact with and try out ORFEO Toolbox?
->Yes the software Monteverdi based on OTB provide a user interface
and an architecture which allows building processing chains by
selecting modules from a set of menus. It supports raster and vector
dataThe architecture takes advantage of the streaming and
multi-threading capabilities of the OTB pipeline. It also uses cool
features as processing on demand and automagic file format I/O. The
application is called Monteverdi, since this is the name of the Orfeo
composer <http://en.wikipedia.org/wiki/Claudio_Monteverdi>. The
application is also packaged on Ubuntu, you can find more informations
here : http://www.orfeo-toolbox.org/otb/monteverdi.html
Moreover the otb-app package provides OTB processing chain (command
line interface) which are also accessible through user interface
(standalone qt application or qgis plugins)
2. OSGeo-Live is memory and disk constrained.
Can ORFEO Toolbox run in 512 Meg or RAM?
->Yes, we already provide in the past Live OTB which works on this
type of platforms. The application monteverdi was developped in the
frame of capacity building activities and it works on PC with memory
and disk constrained (512 Mo of RAM is enough to run the application
and do basic processing).
How much disk space will be required to install ORFEO Toolbox and a
suitable example application.
-> otb package 10 Mo, monteverdi package 10 Mo, otb-app 15 Mo
What datasets would be required for a demonstration? Can you make use of
the naturalearth dataset already installed, or would you need something
else?
http://wiki.osgeo.org/wiki/Live_GIS_Add_Project#Example_Datasets
-> I do not know this dataset, I think that we can use this dataset.
We provide also on our repository extract of remote sensing data which
are used as examples in the software guide and in the OTB tutorial.
http://hg.orfeo-toolbox.org/OTB-Data/
Our documentation (description of algorithms, input images, examples
and results) are automatically generated each time when we update the
software guide to ensure that results which appear in the
documentation are results provided by the library.
We can pointed out interesting "Toy example" if you want which will
give an overview of OTB functionnalities on the Live DVD?
3. You mention that ORFEO is in OSGeo incubation. I can't see ORFEO
listed athttp://osgeo.org. Have you started incubation, or are you on
the waiting list to start incubation?
-> Sorry, I only open a ticket on the OSGeo website to start the
incubation process for now...
4. Stability is very important to us on OSGeo-Live. Do you have a bug
free, stable release, which has been rolled out to production in a
number of locations?
-> The last OTB release 3.8.0 and monteverdi 1.6.0 are the latest
stable release. OTB validation is mainly driven by a platform of
automatic tests (based on cmake, ctest and cdash). The library is
continuously and intensively tests on numerous platforms. There are
more than 1500 tests currently in the library...
http://dash.orfeo-toolbox.org/index.php?project=OTB
5. I notice the CeCILL licence you use is not listed on OSI list of
licences. Has license been discussed and resolved on the
OSGeo-Incubation list?
-> I am not aware of any discussions about the licence, Cecill is a
free software license (adapted to french legal matter) compatible with
GPL : http://en.wikipedia.org/wiki/CeCILL
6. Do you have a person (maybe yourself?) prepared to volunteer to be
the OSGeo-Live representative, who will take responsibility for liaising
between the project and OSGeo-Live and make sure that scripts and
documentation are updated for each release.
-> No problem for liaising between OSGeo and OTB. There is also an OTB
packages team on launchpad with contacts : https://launchpad.net/~otb
<https://launchpad.net/%7Eotb>

Hi Johan,
I think that's some words in your answers are missing... "it is
already packaged and...???"

The toolbox (and also related projects) are also provided
as binary packages for Windows, Mac and recently also on
Linux Platforms. An OTB repository is available on
launchpad.net <http://launchpad.net> for Ubuntu platforms
(9.10,10.4,10.10) and also for OpenSuse platforms.
it is already packaged and
OTB is under incubation for OSGeo Project.
I think it would be a very good idea to include OTB on the
live disk.
