2.1 Create Folders and Move Files

First, move the downloaded raw files into Apollo15/RAW and Apollo17/RAW folders correspondingly.

# Create download folders
mkdir -p Apollo15/RAW Apollo17/RAW

# Move Apollo 15 files
mv M175252641LE.IMG Apollo15/RAW/
mv M175252641RE.IMG Apollo15/RAW/

# Move Apollo 17 files
mv M113758461LE.IMG Apollo17/RAW/
mv M113758461RE.IMG Apollo17/RAW/

# Create calibrated folder for ISIS output
mkdir -p Apollo15/calibrated Apollo17/calibrated

2.2 Create ISIS3 Scripts

Second, create three scripts:

#!/bin/bash
function process()
{
        LROCFILE=$1

        # Cut Extension
        FILELENGTH=${#LROCFILE}-4
        IMGFILE=${LROCFILE:0:FILELENGTH}

        echo "Importing $LROCFILE to isis"
        lronac2isis from=./RAW/"$IMGFILE".IMG to=./calibrated/"$IMGFILE".lev0.cub

        echo "Initializing SPICE kernels"
        spiceinit from=./calibrated/"$IMGFILE".lev0.cub spksmithed=true web=true

        # echo "Calibrating EDR to CDR"
        lronaccal from=./calibrated/"$IMGFILE".lev0.cub to=./calibrated/"$IMGFILE".lev1.cub dark=false

        lronacecho from=./calibrated/"$IMGFILE".lev1.cub to=./calibrated/"$IMGFILE".lev2.cub

        echo "done"
}

IMAGES="./RAW/*.IMG"
for image in $IMAGES
do
    image=$(basename "$image")
    echo "Processing $image"
    process "$image"
done

#!/bin/bash
function process()
{
        LROCFILE=$1

        # Cut Extension
        FILELENGTH=${#LROCFILE}-4
        IMGFILE=${LROCFILE:0:FILELENGTH}

        echo "Mapping"
        cam2map from=./calibrated/"$IMGFILE".lev2.cub to=./calibrated/"$IMGFILE".lev3.cub map=mosaic.map pixres=mpp warpalgorithm=forward

        echo "done"
}

IMAGES="./RAW/*.IMG"
for image in $IMAGES
do
    image=$(basename "$image")
    echo "Processing $image"
    process "$image"
done

ls calibrated/*.lev2.cub > lev2.txt
mosrange fromlist=lev2.txt to=mosaic.map projection=SimpleCylindrical

Note: These commands assume ISIS3 is properly installed and configured on your system. Adjust paths as needed for your specific setup.

2.3 Run Scripts for Both Sites

Third, run the scripts for both the Apollo 15 and Apollo 17 site:

# For Apollo 15
cd Apollo15
chmod +x preprocess_lroc.sh
./preprocess_lroc.sh
./createMosRange.sh
./mappingLROC.sh

# For Apollo 17
cd ../Apollo17
chmod +x preprocess_lroc.sh
./preprocess_lroc.sh
./createMosRange.sh
./mappingLROC.sh

2.4 Create Final Mosaics

Fourth, combine the mapped images into a single mosaic:

# For Apollo 15
cd Apollo15
ls calibrated/*.lev3.cub > lev3.txt
automos fromlist=lev3.txt mosaic=M175252641.cub

# For Apollo 17
cd ../Apollo17
ls calibrated/*.lev3.cub > lev3.txt
automos fromlist=lev3.txt mosaic=M113758461.cub

3.1 Data Structures & Crop Coordinates

To load these images into the program, the NAC images are divided into smaller sub-images and stored in their respective data folders. The script follows the structure below. This dataset was created for and used in the anomaly detection research available at github.com/TechnicToms/lunar-technosignatures:

<chosen data root>/
  LRO/
    NAC/
      Apollo[VERSION]/

Replace [VERSION] with 15 or 17. Place the tiff image into the corresponding directory and crop it as follows:

Apollo 15 Landing Site

Apollo 17 Landing Site

Afterwards, place the ground truths from the GroundTruths folder into the appropriate data folder as listed above.
