UVI campus computers license these ArcGIS progams and extensions through the GeoCAS license server. The server cannot be engaged outside the UVI network. GeoCAS can provide additional functionality in off-campus settings.

If you need off-campus access to ArcGIS using your laptop computer and you are affiliated with UVI (faculty, staff, student), then the process is as follows:

  1. Make an appointment with either Dr. Avram Primack or Dr. Kostas Alexandridis, and bring the laptop you will be using off-campus.
