    GIS Day 2018 Recap

    The University of Arizona Libraries (UAL) Office of Innovation & Stewardship (ODIS) hosted a GIS Day on Wednesday, November 14th . In the morning we facilitated a workshop on Geospatial Analysis with Python which was attended by about 15 people. After lunch, a series of lightning talks by students, faculty and staff displayed the variety of ways that GIS and geospatial technology are being utilizes around campus.

    GIS Day was also a farewell to outgoing Geospatial Support Specialist, Ben Hickson who is moving on from the Library after 4 years of providing support to faculty and students. Ben was also instrumental in the development of the Spatial Data Explorer that UAL now maintains, which offers access to over 3,000 datasets and maps.

    Below are some photos from the event:
