AROSICS

1. Visit this page and read about the package: https://danschef.git-pages.gfz-potsdam.de/arosics/doc/index.html

2. Create a new Anaconda environment using these lines of code (from here):

• conda create -c conda-forge --name arosics python=3

• $ conda activate arosics

3. Install arosics using this line of code:

• conda install -c conda-forge 'arosics>=1.3.0'

4. Run arosics (instructions here). Example: first,

• arosics global -o OUTFILE -br 50 -bs 4 -progress 1 -v 1 -nodata 0 0 -match_gsd 1 REFERENCE_IMAGE INPUT_IMAGE

  • where,

    • global specifies global, as opposed to local, coregistration routine

    • -o OUTFILE specifies the full path to the output file (e.g., /Users/dan.sousa/Desktop/outputfile)

    • -br 50 specifies the band number of the reference image to use (here, band 50 of AVIRISng)

    • -bs 4 specifies the band number of the new image to use (here, band 4 of Sentinel-2)

    • -progress 1 -v 1 specifies that progress written to the screen and the output be verbose

    • -nodata 0 0 specifies the "no data" values of both the reference and new image

    • -match_gsd 1 specifies that the output be matched to the grid of the reference image

    • REFERENCE_IMAGE specifies the full path to the reference image (e.g., (e.g., ~/Desktop/reference)

    • INPUT_IMAGE specifies the full path to the input file (e.g., ~/Desktop/inputfile)

and then,

• arosics local -o OUTFILE -br 50 -bs 4 -progress 1 -v 1 -nodata 0 0 REFERENCE_IMAGE INPUT_IMAGE 50

  • where,

    • local specifies local, as opposed to global, coregistration routine

    • -o OUTFILE specifies the full path to the output file (e.g., /Users/dan.sousa/Desktop/outputfile)

    • -br 50 specifies the band number of the reference image to use (here, band 50 of AVIRISng)

    • -bs 4 specifies the band number of the new image to use (here, band 4 of Sentinel-2)

    • -progress 1 -v 1 specifies that progress written to the screen and the output be verbose

    • -nodata 0 0 specifies the "no data" values of both the reference and new image

    • REFERENCE_IMAGE specifies the full path to the reference image (e.g., (e.g., ~/Desktop/reference)

    • INPUT_IMAGE specifies the full path to the input file (e.g., ~/Desktop/inputfile)

    • 50 specifies the pixel spacing of the tie point grid
