What is Orfeo Toolbox (OTB)?
Initiated by CNES (French Space Agency)
I Following the feedback from SPOT satellite seriesI In the frame of CNES ORFEO Program to prepare the launch of
Pleiades (2011)
GoalMake the development of new algorithms and their validation easier
Why?
I Traditionally (SPOT satellites): provide image simulationsI But here jump in resolution ⇒ develop new R&D methodsI To bridge the common gap between R&D study and tools available ⇒

Progress
Everything begins (2006)I Started in 2006 by CNES (French Space Agency), funding several full-time
developersI Targeted at high resolution images but with application to other sensorsI 4 year budget, over 1,000,000e recently renewed for 1 additional year
(500,000e)
Moving to user friendly applications (2008)I Strong interactions with the end-user community highlighted that applications for
non-programmers are importantI Several applications for non programmers (with GUI) since early 2008I Several training courses (3/5-day courses) given in France, Belgium,

Why doing that?
Why make a multi-million dollar software and give it forfree?
I The French space agency (CNES) is not a software company, its goal is topromote space technologies and encourage the development of newapplications.
I CNES makes satellites and wants to make sure the images are usedI One goal is to encourage research: it is critical for researchers to know what is in

Capacity buildingI Strong demand to provide tools for capacity buildingI Decision to start an integrated application based on OTBI Developpement started last year (September 2009)
National & European environmental policyI In the frame of water & nitrate European directivesI Mapping natural area for biodiversity assessment and protectionI Potential of VHSR imagery
I From best effort to productionI Different category of users without remote sensing knowledgeI Ecology minister regional delegations ⇒ Package : OTB + QGIS + Pleiades
GIS integrationI Need for an “operational & validated methodology” applied at regional scaleI More interaction between remote sensing and GIS applicationI Drive the development of OTB/QGIS plugins

GIS in OTBSeveral softwares
I Integration of Mapnik with reprojection to display vector dataI PostGIS, SpatiaLite integrationI Use of Open Street Map data for image to database registration

Done yesterday (thanks to J. Malik)
With all tools included in OTBI Data read by GdalI GCP entered in MonteverdiI with tiles from OSMI RPC model by OssimI resampling by ITKI OSM shapefile read with OGRI rendered with MapnikI soon in QGIS

QGIS integration
Quantum GIS plugins (C++)I Create otbgui (qtdesigner)I Create HillShadeFilter (based on the OTB example)I Add the plugin to the otb generic plugin constructorI Drawback: need to develop a new plugin for each feature
