Data:
Enhanced “Value-Added” Image Products
Orthorectified Images
Radiometrically Corrected Images
Radar Mosaics
Ascending-Descending Merges
Data available in 16 bit (“detected”) & 32 bit (“complex”)
*So many different combinations of available data*

3. Mission: Objectives: TanDEM-X Mission:
TanDEM... DEM of somewhere in Bolivia
Mission:
Objectives:
provision of X-band SAR-data for scientific research and applications
establishment of a commercial Earth Observation (EO) market and to develop a sustainable EO-service business, based on TerraSAR-X derived information products
TerraSAR & TanDEM
TanDEM-X Mission:
Launched summer 2010
Goal: Create global DEM in 3 years
12 m. resolution, <2 m. vertical accuracy
1.5 petabytes expected
1,000,000,000,000,000 B (at 8bits/B)

4. Some of the many areas of use for TerraSAR data:
security and defence 
topographic and thematic mapping
agriculture: crop mapping etc. see below! 
forestry applications
urban and regional planning 
coastal management and vessel monitoring 
geology
hazard & disaster management
Snow & Glaciers

5. HST Slide... References TerraSAR Take Home Messages:
TerraSAR is unique in its ability to switch & redirect its sensors quickly
TerraSAR offers a wide variety of “products”, not just raw data
Imaging modes, polarization, frequency, product types
Therefore Price depends upon what you want
