The ICOL+ processor graphical user interface is represented by one main dialog, which
consists of the following components:
4.1. I/O Parameters Tab Pane
This tab pane (
Figure 4.1)
consists of the following components:
-
Input product file: Select the input product file by pressing the file selection button to invoke
a standard file dialog.
-
MERIS: Select a L1 product given in .N1 or BEAM-DIMAP format
-
LANDSAT TM: Select a L1 product given in GEOTIFF (original product) or BEAM-DIMAP format
('Geometry' product, see Section 3.1).
A large number of Landsat TM products in GEOTIFF format can be found at the USGS
Earth Explorer site ([RD-5]). To process TM GEOTIFF data in ICOL, do the following steps:
-
The data from [RD-5]usually come
in gzipped format named like 'LT5...tar.gz'. If so, unpack this archive.
-
The unpacked product should consist of seven single .tif files and two metafiles with suffixes
'_MTL.txt' and '_GCP.txt'.
-
Select the file '..._MTL.txt' as input file.
-
Output product file: Select the output product file by typing the product filename into the text
field.
-
Output product format and target directory:
-
'Save as': If this checkbox is selected, the output product will be saved to disk.
-
Output product format: Select one of the available output product formats.
For MERIS, these are:
-
BEAM-DIMAP
-
NETCDF
-
N1 (in case the input product is a .N1 file and the output product has been selected
as 'Radiance Product' (see below). In this case, the output product contains the
same bands as the input N1 product. This allows the AE corrected product to be re-used
as input for many other BEAM processors (such as Case 2 Regional) within a processing
chain.
For LANDSAT TM, these are:
-
BEAM-DIMAP
-
NETCDF
-
GeoTIFF
-
Select the output product directory by either typing the product path into the text
filed or by pressing the file selection button to invoke a standard file dialog.
-
'Open in Visat': If this checkbox is selected, the output product is opened in Visat
after successful processing.
