Epina ImageLab stores the raw data of an image and the associated metadata in three files (*.ilab, *.imsk and *.cube), which are optimized for high speed access to the data. For some purposes, it is necessary to get access to (parts of) the data in a readable form, which may be accomplished by exporting the data of interest:

How to export |
| Entire Data Set
|
There are several options to export the entire data set: (1) Use the command File>Export Data>Formatted Text File, (2) use the command File>Export Data>XML Format, (3) export it to a CSV file (automatically generating a MatLab m-file to import it in MatLab). (4) export it as an ASC formatted file (mainly used as an import format for DataLab). (5) Export the data as an IGTIF data file. The IGTIF format is the most general one and is recommended unless you want to import the data by MatLab or DataLab. (6) Export the data in ENVI format.
Hint: Please keep in mind that the export of the entire data set results in files whose size may be in the GByte range. |
| Individual Spectra |
Use the 2D Imager, display the interesting spectrum and right-click the chart at the right which shows the spectrum. Select "Export Data" from the context menu.1)
|
| Images |
Display the required image in the 2D Imager and right-click the image. Select "Export Data" from the context menu.1) |
| Cross Sections |
Use the 2D Imager, display the required cross section and right-click the chart at the right which shows the cross section. Select "Export Data" from the context menu.1)
|
| Spectral Descriptors |
Use the command "File>Export Data>Spectral Descriptors".1) |
| Hint: |
Another, very efficient way to specifically access and export data, is to use the scripting engine ILabPascal which provides a large function library supporting the eport of data. |
