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

Figure 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 5 TM or Landsat 7 ETM+: Select a L1 product given in GEOTIFF. A large number of Landsat TM products in GEOTIFF format can be found at the USGS Earth Explorer site ([RD-6]). To process TM GEOTIFF data in ICOL, do the following steps:
    • The data from [RD-6]usually come in gzipped format named like 'LT5...tar.gz'. If so, unpack this archive.
    • The unpacked product should consist of seven (TM) or eight (ETM+) single .tif files and two metafiles with suffixes '_MTL.txt' and '_GCP.txt'.
    • Select the file '..._MTL.txt' as input file.
    After successful selection, the target product name field will be disabled and will show a name with suffix '_downscaled'. This name cannot be changed by the user. Also, the target directory text field will disappear, as this needs to be set on the LANDSAT TM tab pane (see below).
• 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
    • ENVISAT (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 and ETM+, these are:
    • BEAM-DIMAP
    • NETCDF
    • GeoTIFF
  • MERIS only: 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.
