• TWB uses a lot of software, can be time-consuming to install, so we put it into a Virtual Machine (VM).
A VM is a copy of Windows running inside Windows. (or Windows inside MacOS, or Linux)
• Saves a lot of time & makes it easy to experiment with workflows
• Don’t use for production modelling.
• We can give VMs to CSIRO staff, not others.
• ArcGIS licence times out on Friday!
