Regions acquired from May 2013

Current opportunities and developments

• AO for Intermediate DEM in preparation. Will be published in coming weeks. Stay tuned on TD-X Science System.

• AO for CoSSC data open during TDX Lifetime

• 4th TanDEM-X Science Team Meeting 12-14 June 2013• 105 registered participants + 35 oral presentation + 15 posters• Great potential for forest characterization and stratification revealed• Discussions on after DEM Phase planning for scientific TanDEM-X

acquisitions:• Acquisition Mode (DRA, long baseline across/along InSAR)• Test site definition (e.g. super test sites)• Time schedule

Slide 14

TanDEM-X Data Delivery • Since February 2012 EOWEB is open for TanDEM-X data delivery

• 148 accounts are opened up to now

• 1801 CoSSC products delivered

Final DEM Preliminary Schedule

Start of TanDEM-X DEM delivery Jan-2014

(non-difficult areas requiring only 2 acquisitions)

~50% of the global TanDEM-X DEM end 2014

~90% of the global TanDEM-X DEM mid 2015

~97% of the global TanDEM-X DEM early 2016

Summary – DLR Data access for GFOI R&D

• TerraSAR-X: DLR Science Service Seg.: http://sss.terrasar-x.dlr.de/

• TanDEM-X (DEM) data access: https://tandemx-science.dlr.de/

• RapidEye data available through RapidEye company directly, but scientific exploitation also through DLR RapidEye Science Archive: http://resaweb.dlr.de/

• Collaboration between international GFOI R&D groups and German researchers sought. Contacts can be made.

• DLR ready for more coordinated approach with respect to GFOI R&D through CEOS

TerraSAR-X and TanDEM-X Summary

Public Private Partnership between DLR and EADS Astrium Germany

Both satellites – TerraSAR-X and TanDEM-X – are in very good health Continue/optimize acquisition for validation sites, support scientific exploitation of data, continuity (Constellation with Paz, TerraSAR-X NG) planned

Actual GFOI R&D (FCT) Contribution

FCT Validation sites are established as background mission

Data access along DLR procedures

Potential GFOI contributionBilateral demonstration projects

existing/envisaged (Africa, Latin America)

Framework needed for „GFOI approach“

Other relevant DLR activities

• Funding development/improvement of relevant methods for REDD+ and GFOI, such as automated, large area monitoring of changes in forest cover and landuse, forest degradation, etc.

• Focus on synergistic use of Sentinels and German missions• Coordination/collaboration with GFOI teams being sought• Examples:

• SENSE-CARBON Project (started in May 2013, Humboldt-Uni Berlin, Uni Bonn, Study area in Amazonia)

• Project with TerraSAR-X in Ecuador (Uni Freiburg)• More projects in preparation (encompassing bistatic TanDEM-X

data)• Workshop with relevant German officials, providers, researchers and

international partners (see www.d-geo.de/redd)

• Support of literature study and database (see www.redd.uni-jena.de/index_en.html)

German REDD+ development cooperation• Numerous bilateral activities, incl. Satellite data, monitoring systems and

related capacity building• Ongoing MRV projects in SADC, Ghana, Indonesia, Latin America)• From 2013 on, investment of € 500 Mio/year for forestry and biodiversity • New “REDD Early Movers” program providing, among others,

performance payments for quantified emission reductions

• Key investor in the Forest Carbon Partnership Facility (FCPF) and other multilateral mechanisms

• ICI financed “CD-REDD” Project in 18 countries additional to UN-REDD countries

Mexico and adjacent countries (southwards)

• Transfer of Mexican NFMS to Central America region, as a South2South Cooperation

• Includes RapidEye wall2wall data

• TSX-TDX Data (e.g. sample plots) also proposed to be included

• Implementation proposed to German and Norwegian Government for funding
