FAQ

Can I load IRS-1D data in IMAGINE?

Yes, you can.

IMAGINE 8.4

contains an importer for IRS-1D data.

IMAGINE 8.3

IRS-1D data can be imported by using the IRS-1C importer (IRS-1C Euromap Fast Format C). The import procedure is slightly different, because we had to expand the naming conventions for IRS-1D. Therefore the IRS-1C importer is unable to identify the data and header files automatically.

You will find an import example for IRS-1D PAN and LISS data sets below.

PAN data:

1. choose Import | Euromap IRS-1C (Euromap Fast Format C)
2. Media: File
3. select Input-Directory + File: e.g. f:/24_34D/H0D0Y867.07A (header file according to the naming conventions [the smaller of the two files])
4. enter Output-Directory + File: <output>
5. now click OK
6. in the "IRS-1C Band File Error" dialog-box that appears, click Select Band File(s)
7. select the data file (e.g. H0D0Y867.070) in the window that appears
8. assign this file to band 1 by using the button Band # 1 SET
9. now click OK and the "IRS-1C Information" should display all header information correctly
10. from here you can proceed as usual: i.e. click Preview or OK to read the entire scene

LISS data:

1. choose Import | Euromap IRS-1C (Euromap Fast Format C)
2. Media: File
3. select Input-Directory + File: e.g. f:/24_34Q4/N0O0Y867.0FL (header file according to the naming conventions [the smallest file])
4. enter Output-Directory + File: <output>
5. now click OK
6. in the "IRS-1C Band File Error" dialog-box that appears, click Select Band File(s)
7. in the window that appears select the data files which correspond to data channels
   e.g. N0O0Y867.0FM = band 1
   and N0O0Y867.0FN = band 2 ... etc.
   
8. assign the file N0O0Y867.0FM to band 1 using the button "Band # 1 SET",
   assign the file N0O0Y867.0FN to band 2 using the button "Band # 2 SET" ... etc.
   until all four bands are selected. The optional synthetic blue channel has to be read instead of one of the four LISS bands or has to be imported later as a separate band. (five bands can not be imported as "LISS" at the same time)
9. now click OK and the "IRS-1C Information" should display all header information correctly
10. from here you can proceed as usual: i.e. click Preview or OK to read the entire scene
