Maps & geospatial data
McGill Library collects geospatial data primarily for the Montreal region, secondarily for Quebec, Canada and the United States. For technical assistance with data, contact the Geographic Information Centre (GIC). The GIC actively supports the teaching, learning, and research activities of McGill University in the areas of Geographic Information Systems and Remote Sensing.
Most of the data sets in the Library's collection are licensed to McGill University; use of these data are restricted to students, faculty, and staff for academic teaching and research purposes. Users are required to fill out a Geospatial Data Request form and sign a Data License Agreement before using the files.
