4SM executable code is for Intel x86 CPU in a 32 bits UbuntuLinux/Gnome/bash environment.
MS addicts: most prospective "would-be" 4SM users are stuck with their own MS setup. They won't hear of installing Linux on their machine.
Cloud computing appears to be the solution these days: I see several advantages
4SMguest users on Server shall have a great 4SM-tutorials experience from inside their petty MS session wherever they happen to sit, provided they practise in the basics of using the Server's UbuntuLinux/GNOME/bash environment.
Then later they should love to connect to Server, load they petty image and start playing privately with it on their own, see what gives.
Then eventually decide to request/pay for a 4SM licensekey for their image for full unrestricted 4SM processing, once in a while.
Then some heavy users might want to upgrade to superuser status for commercial 4SM services purposes.
Be quick : register your interest for setting up an Ubuntu server for open cloud use
for 4SM tutorials
for 4SM processing of archive images
for 4SM processing of current project images
for staging a "Water Column Correction contest" for anyone to put forward their own solution under some kind of steering comitee (academics and businesses),
where the same imagery and ancillary data would be made available to interested competitors
where the steering comitee would rate each contribution and publish their assessment
