This data set comprises low-resolution browse products of system corrected ,
geocoded and terrain corrected ERS_SAR data (GTC) of the European Remote
Sensing Satellite (ERS-1); on-line access is offered by means of the
Intelligent Satellite Data Information System ISIS, a service of the DFD within
DLR at Oberpfaffenhofen, Germany.
Description of the offered GTC ... data set:
The ERS_SAR Terrain Geocoded Image dataset is a multi-look,
ground range projected, system-corrected digital image. Furthermore,
it is precisely located and rectified onto a map projection, as well as
corrected for terrain distortion. Currently, it is presently the highest level
SAR image product and is intended for Users interested in remote sensing
applications in hilly terrain and where the geometry of the image is important.
The cartographic reference system is UTM for latitudes within -80 deg and
+84 deg., all else with UPS system. The ellipsoid is WGS 1984. Resampling
is performed by Cubic Convolution.
Original data are processed and stored at DFD. They have been downscaled
for distribution as browse image. Total image size of such scene is about
100 km square, with ca. 100 m pixel spacing. The volume of a scene is about
Access to the data:
On-line access to data and information is provided by the Intelligent Satellite
Data Information System ISIS, developed by DLR as a client / server
configuration. It is representing the interface of DLR-DFD to users, providing
an easy access to catalogue-, inventory-, browse- and general textual
The URl is: http://isis.dlr.de/.
Relevant procedures to access this system are described in a separate entry
in the catagory `Data Center` and may be queried by interested people. Access
presumes the installation of the client configuration which can be easily done
by the user on his computer configuration.
