Le portail francophone de la géomatique

Le lancement a été couronné de succès fin septembre.

Ca nous fera plein de belles images gratuites pour l'Amérique du Sud !

Salut Sylvain,

Bien sûr que j'ai des infos supplémentaires

The Lauch of CBERS-2B (14/09/07)

On Tuesday 18th, at 11 p.m., from the Satellite Control and Tracking Centre of
the National Institute for Space Research(INPE), in São José dos Campos (SP),
technicians and guests will be able to watch the launch of CBERS-2B by the Long
March 4B Rocket from Taiyuan Satellite Launch Center.

All launching stages of the China-Brazil Satellite will be informed by the
Director of INPE, Gilberto Câmara, and the CBERS Program Coordinator, Ricardo
Cartaxo, by teleconference directly from China.

On Wednesday 19th, at 10 a.m., the first passage of the satellite over Brazilian
territory will be registered. This event will also be watched by the Satellite
Control and Tracking Centre at INPE.

CBERS-2B is the third satellite from a partnership with China, which has become
indispensable to Brazil. Since 2004, when the free distribution on the internet
began, more than 320 thousand images of CBERS were downloaded by around 15
thousand users from institutions such as INCRA and IBAMA, universities, non
governmental and private organizations.

The satellite has three imaging cameras on board: CCD, WFI and HRC, this last is
a high resolution panchromatic one (2,5 m). The diversity of cameras supplies
the necessities from urban planning, which requires high spatial resolution, to
applications that need frequent, but not specific data, such as agriculture and
deforestation.

CBERS-2B will guarantee that the supply of images, started in 1999 with CBERS-1,
won't be interrupted. The estimated useful life of the satellites CBERS 1, 2 and
2B is two years and for the satellites CBERS 3 and 4, it is three years. CBERS-1
operated successfully until August 2003, beyond its useful life, an outcome that
has been repeated with CBERS-2. The launch of CBERS-3 is foreseen for 2009, and
CBERS-4, for 2011.


Après, on peut aller sur ce site en anglais : http://www.cbers.inpe.br/?hl=en

Il y a un lien direct vers le catalogue d'images, qui lui est en portugais, mais assez aisément compréhensible pour qui a l'habitude des catalogues en ligne.
A noter, qu'il faut s'enregistrer ("cadastre-se") pour pouvoir sauvegarder et télécharger les images.

Le catalogue comprend des images Landsat 1,2,3 et CBERS -2, mais pas encore CBERS-2B le petit nouveau encore en test.

Amicalement,
Matthieu

Ca doit être une question d'accord commercial.
Le Brésil propose ca pour l'Amérique du Sud, pour le reste, il est peut-être possible de les acheter du côté chinois...

En fait le Brésil dispose des compétences de traitement et de conception du sat, tandis que les chinois disposent du lanceur (élément le plus cher) et des financements. Donc je pense que l'exploitation du reste du monde doit être du ressort de la Chine, mais je n'en sais pas plus... En tous cas, ce n'est pas gratuit pour le reste du monde.
