test_example_ISCE_stripmapApp.md

1. Download the directory "test_example_ISCE_stripmapApp" from the link.

2. Under test_example_ISCE_stripmapApp/, you will find the flag_file (flagfile.txt), link_file (linkfile.txt), ref_file (Howland_LVIS_NaN.tif), mask_file (Maine_NLCD2011_nonwildland.tif). All of the associated files for three ALOS PALSAR HV-pol InSAR coherence scenes are grouped by their ALOS (f$frame_o$orbit) and their acquisition dates (under the subfolder int_$date1_$date2). For each scene, there are five associated files outputted by ISCE: stripmapProc.xml, resampOnlyImage.amp.geo, resampOnlyImage.amp.geo.xml, topophase.cor.geo, topophase.cor.geo.xml. This page serves as the instructions for running the FSH software over this test example directory. Finally, an image ISCE.png shows the final output of 3-scene mosaic map (GeoTiff format) overlaid on Google Earth in a QGIS window.

Note: all of the ALOS images files have already been margin-cropped and geocoded in the pre-processing by ISCE as described here.

3. Run the 1-command FSH auto-inversion as described here

   python <full_path_to_directory_of_scripts>forest_stand_height.py 3 2 2 5 \
   "linkfile.txt" \
   "flagfile.txt" \
   "Howland_LVIS_NaN.tif" \
   "Maine_NLCD2011_nonwildland.tif" \
   "<full_path_to_directory_of_test_example>" \
   "gif json kml mat tif" \
   --flag_diff=1 --flag_error=1  --flag_proc=1
   

4. Run the 1-command FSH mosaicking as described here

   python <full_path_to_directory_of_scripts>create_mosaic.py \
   "<full_path_to_directory_of_test_example>" "3sc_mosaic.tif" 
   

5. Open the final output 3sc_mosaic.tif in QGIS.

Note: We use <> symbol as representation of a directory, don't type it as input. If the directory of scripts are added to the path and Python path environmental variables, it can be omitted.
