You need to install osgeo4w (You just need GDAL) found here https://trac.osgeo.org/osgeo4w/
Here is the link to the jp2 to tif program https://drive.google.com/file/d/0BzHmCf…iew?usp=sharing
configure the maketif_config.txt file (make sure to keep double backslashes between folders C:\\myfolder\\mysubfolder\\
click the maketif.exe or run from command prompt
program reads in a folder of JP2s, converts them to tif, projects them to lat/long and at the end writes the tfw files.
If i have some time this weekend I will have it make the tmc for the total area as well.
Let me know if you have any questions or problems
