The short answer is no. The computers in the Lab share an internal network, but do not connect to the ACS or other UCSD networks.
This means that you have to bring all the documents and data you need for your GIS work on some sort of media.
We suggest using a flash drive (2GB or larger), but other less than optimal options include CD/DVD-ROMs and emailing your files to yourself.
You’ll also want to have media to save your GIS work to as the Lab does not offer secure, long-term file space.
