Purpose
Standard products are imported into the SARscape Data Format for further processing.
Technical Note
The import functionality requires, as mandatory input, only the Parameter file(s). The original data structure must be kept as in the original standard product.
Orbit File
This is an optional input, which is intended for using the precise orbits instead of the standard ones. RADARSAT-2 orbit files can be requested when the standard products are ordered. If orbit files are not initially requested they may be obtained at any time by contacting the MDA client services department. This input can be used only importing SLC products.
If the relevant precise orbit files are already stored in an existing folder, which has been defined as RADARSAT-2 Directory (Preferences common), they do not have to be inputted in the import processing panel since they are automatically retrieved by the program.
Data in NITF format are also supported. To ingest them, the following procedure must be adopted:
•Import the data using the ENVI own functionality "File>Open External File>Military>NITF>NITF".
•Save the imported image in ENVI format using "File>Save file as>ENVI Standard". Before saving you must cancel the ".NITF" proposed extension from the output file name.
•Import the data in SARscape using this module.

Output Files
Output file list
Output file name(s) of the imported data. These files are mandatory.
Root name of the imported file(s) and associated header files (.sml, .hdr). Specific file suffixes are added according to the data type.
.shp
Shape file and associated header files (.sml, .hdr) containing the image perimeter in geographic co-ordinates.
.kml
ASCII file containing the image perimeter in geographic co-ordinates. Double clicking on this file will automatically position the boundaries of the scene into the Google Earth environment.
Details specific to the Units of Measure and Nomenclature of the output products can be found in the Data Format section.
