Q:
I have thousands of HDF-EOS data sets I want to use with HEG. It's too time-consuming to use the GUI one at a time. What can I do?Anchor multipleDatasets multipleDatasets
A: You can stack many runs on the GUI's Accepted List, but for more than 5-10 runs, it's still cumbersome to open files and load up options. What you need is to run HEG on the "Commmand Line". There are quite a few users who do this and they almost always need some guidance getting started.
Q:
What do I need to start running on the "Command Line"?Anchor commandLine commandLine
A: You need 3 things to get started (trying to keep things simple for now):
...
Q:
How does this run the thousands of HDF-EOS data sets?Anchor thousandsOfDatasets thousandsOfDatasets
A: The parameter file can stack up thousands of runs. Each run is a block of text with a BEGIN and END part.
Q:
How do I make a parameter file?Anchor parameterFile parameterFile
A: Instructions are in the HEG User's Guide, but a much easier way is to load one data set into the GUI, set your options (i.e output format, type of reprojection, field to work on, etc). Once your run is on the "Accepted List", then stack another another run in the "Accepted List". Then "save" it. This will save the parameter file. You'll be asked where to save it. Use this parameter file as a "TEMPLATE". There are simple fields such as input filename, output filename, output projection type, etc. Note how you've saved more than one run. Because of this, you'll see how more than one run can be inside a parameter file (i.e. NUM_RUN = 2 on the top line).
Q:
Is there another way of running batch job for processing thousands of HDF-EOS data sets?Anchor batchJob batchJob
A: Yes. You may also use an script for the batch HEG job for processing a bunch of similar files on Command line.
Q:
The parameter file has the extents (corner points) of the input data set. How can I know what these are?Anchor cornerPoints cornerPoints
A: There is a program called "hegtool" which is in the bin directory.
Set your ENVIRONMENT VARIABLES, then run it as such:
