MDT Distance Calculator Data Files <<Back To get the data files for this application click on this link: points.tar.gz and download this file to your cgi-bin/mdtdist  directory on your UNIX or Linux web server. If you are downloading this file to a PC or Mac and then intend to upload it to a UNIX machine, be sure to save the file as points.tar.gz, then ftp it as a binary file called points.tar.gz. Once the file is in place use the gzip utility to expand the files by typing: gunzip points.tar.gz If you don't have this freeware compression utility you can get it at: ftp://ftp.netscape.com/pub/unsupported/gnu/ Once the file is unzipped it will be in this format: points.tar To untar this file type the following: tar -xvf points.tar The result should be the points directory, which contains the various files with the points along the MDT and their distances from the western terminus. Be sure to chmod these files to 755  and chmod the points directory itself to 777.  If you downloaded this file to the correct location and your $points_directory variable in your mdtdist.pl file points to this location, then the program will have no problem reading these files
