Selecting a Data Set to Import

To select a data set to import, navigate through the contents of the file in the Contents pane. Click the plus sign at the left of the filename. This expands the hierarchical table of contents, listing the data sets in the file.

When you select a data set in the Contents pane, the HDF Import Tool displays the metadata associated with the data set in the Metadata pane, such as the size of each dimension.

The HDF Import Tool displays any subsetting options that exist for that type of data in the Importing and Subsetting pane.

Note    The Importing and Subsetting pane might remain empty, even after you have selected items in the Contents pane, if the item is not a data set. For certain types of data, such as HDF-EOS Grid data, you have to navigate down several levels of the hierarchy to reach a data set.

For example, this figure shows the expanded table of contents in the Contents pane, with the data set Example SDS selected. Note how the Metadata pane contains information about the data set. The Importing and Subsetting pane displays the subsetting options available and the workspace variable name assigned to the data set by default. See Data Subsetting Options for more information about these data subsetting options.

Selecting the View.   For HDF-EOS files, the HDF Import Tool Contents pane can provide two different views of the file contents: as an HDF file or as an HDF-EOS file. HDF-EOS files can be viewed as HDF files because the EOS standard is built on the HDF standard. HDF files, however, cannot be viewed as EOS files.

You can switch the Contents pane to provide only an HDF view or only an HDF-EOS view of your files, or you can display both views of your files simultaneously, as illustrated in this figure.

Note    Although HDF-EOS files can appear in both windows of the Contents pane, remember that you are getting two different views of the same file.
