GIS Help Desk

The CGA offers free GIS helpdesk for 30 minute to 1 hour consultations to those with a valid HUID.  Additional work on GIS projects can be defined with a Project Specification, and will be charged at the rate of $85/hr for Harvard affiliates. If you have funding and would like us to perform the requested mapping or analysis for you and deliever the results, please see the details on our project consulation page.

Please contact us to set up an appointment during Helpdesk office hours below or at another time.

Starting July 2018, due to a reduction in staff resources dedicated to the CGA Help Desk, response time will be 2 – 10 business days. We are very sorry for this inconvenience, and encourage you to find GIS support through other channels, such as online tutorials.

Normal office hours every Tuesday, 1:30 pm - 4:00 pm. During the summer break by appointment only.
