If you see or hear a plane flying low over the UC Berkeley campus this weekend, don’t be alarmed.

The UC Berkeley Real Estate Mapping and Drawing unit has hired a company to make a highly-detailed topographic map of the campus. The plane is taking aerial pictures of the campus, the hills east of the campus, and Lawrence Berkeley National Laboratory.

To get detailed photos, the small plane will have to fly repeatedly over the campus at about a 3,000-foot elevation. Cal officials aren’t certain the hours the plane will be flying as it is dependent on the weather, according to Christine Shaff, a spokeswoman for the university’s Real Estate Division. The plane will be in the air around two hours on both Saturday and Sunday.
