[Live-demo] ORFEO Toolbox in OSGeoLive?

[Manuel Grizonnet]

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

<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/
<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 at http://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...

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
