The document summarizes the DUSP GIS Data Drive (also known as the 'M' Drive), which contains geospatial data for DUSP students, staff, and faculty. It can be accessed by mapping a network drive on campus or through the MIT VPN off campus. The drive contains a wide range of datasets that can be used by the DUSP community with documentation reviewed carefully. Contributing data requires contacting the GIS specialist Mike Foster.
