Why Use TerraSAR-X Data?

Resolution

TerraSAR-X is capable of providing imagery of up to 1 metre resolution so you can compliment your high resolution optical imagery with high resolution SAR data.

Flexibility

TerraSAR-X provides three imaging modes coupled with multiple options for polarization and swath width, allowing you to purchase an image product specifically tailored to your application.

Coverage

TerraSAR-X is able to image in all weather conditions, as well as day and night.

 

Why Use TerraSAR-X Data?

Geomatica TerraSAR-X support leads the industry for the following workflows:

About TerraSAR-X

TerraSAR-X’s highly anticipated launch on June 15, 2007 was a resounding success. The satellite features an advanced X-band SAR that can be operated in several different modes and polarizations.

The table below summarizes the technical details, benefits, and applications of each imaging mode.
