Equipment & Software

Members of our Smith community are welcome to borrow GPS equipment for teaching and research. Please consult the following details and contact the Spatial Data Specialist to schedule a time to learn how to use the equipment and pick up. If you’re interested in incorporating drones in your teaching or research, please contact Jon ( and review our campus UAS policy.

The SAL uses and maintains (more or less) a variety of drones from DJI Phantom 4 RTK to the Mini 3 Pro.  Most of our drones are used for mapping and we look forward to working with students and faculty to support research efforts that need high spatial resolution imagery.  Our partners in the drone space include the Geosciences, Biology, the Imaging Center and the Botanic Garden.  

Some of our work can be found by search on "drone" on this website, or Vimeo channel,  or in the ArcGIS Online Gallery.  

Base Station

We maintain one of the National Geodetic Survey's Continuously Operation Reference Stations (CORS) - HAMP. Here's the direct data link, and please contact Kala'i ( for information on how to access the RTK differential stream.
