The application ctsmapper.exe that was included in Gibbed SR2 Tools does not seem to work. So I make a new program sr2ctsmapper.exe. You just drag <name>.cts file and drop it on the sr2ctsmapper.exe. <name>.png file was created and xy(z) coodinate infomation displayed with colored "+" mark. Ver2.0 added map viewer function and you can get detailed coodinate information.
