Other Tool for Searching ASTER Data
• ASTER Browse Tool --- USGS Global Visualization Viewer
http://glovis.usgs.gov/
http://edcdaac.usgs.gov/aster/glovis.html
• New release version 3.0 of GloVis support for display ASTER Decorrelated Stretch VNIR browse images by using Level 1B metadata.
• The inventory of ASTER granules is current through the end of May 2002. Infrastructure is being put into place to keep the inventory up-to-date on a daily basis, but it is not ready yet.
• Directly ordering ASTER granules is not yet supported as this time. We are in the process of designing the shopping cart option.

http://winvicar.jpl.nasa.gov/From Beta test, register and then JPL will send you the software download instruction.Follow the instructions for installation. The command used for handling HDF format is “hdfextract”.

Check ‘Write Transform to Image’, the ‘Transformation Order’ 1 will be the default setting. Click on ‘OK’, and you’ll get imported image. For SWIR and TIR bands image import, just use ‘Next Image’ on ‘Importer’ window to identify bands needed to be imported with ‘Correction’ option. The output image file is in Lat/Long geographic coordinate system. You can re-project it to UTM projection from there.
II. Read ASTER L1B data in ERDAS 8.5 with georeferencing information:

III. ENVI 3.5 continue
Path-Oriented image North-Up image, in UTM projection

IV. Read ASTER L1B data in PCI with georeferencing information:
1. Setup Project:Start Ortho-engine main manual bar; ‘File’ ‘New’ to setup your new project criteria.
Click on ‘Accept’, Click ‘Metre’ on “Set Projection” window, chose ‘UTM’ from the drop down panel. Two popup windows will prompt you to choose UTM zones and rows.

IV. PCI continue
After the selection step of ‘Output Projection’ parameters, click on ‘Set GCP Projection based on Output Projection’ bar near bottom, you’ll see all the parameters from what you just defined.
Click ‘Accept’

IV. PCI continue
You can either select a single band, or one group of telescope as shown next, click ‘read’.
2. Data Input:Select ‘Data Input’ under ‘Processing Step’,Click on the first button for reading ASTER HDF-EOS data in.

IV. PCI continue3. Ortho-image generation: a. Open image file: On OrthoEngine main manual bar, chose ‘Ortho Generation’ under ‘Processing Step’, click on first button to open image (*.pix) that just created from last step.
Select bands and click ‘Load & Close’. Image view windows will popup.
Land Processes Distributed Archive Center (LP DAAC) http://lpdaac.usgs.gov/main.html
IV. PCI continueb. Ortho image generation:
Click on the third button to schedule ortho generation,
Chose from upper left panel from ‘Available Image’ list, click on the arrow button between ‘Available Image’ panel and ‘Images to Process’ panel.
Land Processes Distributed Archive Center (LP DAAC) http://lpdaac.usgs.gov/main.html
IV. PCI continue
Change ‘Resampling:’ under ‘Processing Option’ from default ‘Nearest’ to ‘Cubic’,
Click ‘Generate Orthos’ button will start the processing.
The ortho image of ASTER VNIR three bands will have the UTM projection information embedded in the *.pix file.

IV. PCI continue
4. Export PCI image format to other image format: To export it to any other format, from OrthoEngine main manual bar, ‘File’ ‘File Utility…’ window,
Make your selection of data need to be exported, click ‘Add’ will active ‘Export’ button. Click ‘Export’.
‘File’ ‘Export to …’; you will see list of options for your output image format. Taking output to ERDAS Imagine format as an example here:
