Massachusetts GIS Day

Permanent URI for this collection

Massachusetts GIS Day is an annual celebration of geospatial technology and the tools and approaches that makes up the the field of geographic information science. The event is a collaboration of organizations across the Commonwealth, featuring posters, lightning talks, and guest speakers.

This site is a repository for materials presented at MA GIS Day, starting with its 2020 inaugural year.

    Correlational Analysis of Mammals and Residential Land Use: Amherst, MA
    (2021-12-20) Gutkowski, Ella
    Mammal diversity varies in different types of land uses. Residential land use oftentimes interferes with the natural occurrence of mammal species. This study conducts a correlational analysis using camera trap data from Excel and land use data in GIS to uncover whether humans have disrupted mammal occurrence in residential land use areas in Amherst, MA. Results reveal that human activity in residential land use areas in Amherst did not strongly influence the occurrence of these mammals.

    Who Bears the Burden? Racial Disparities in Confirmed Cases of COVID-19 in the Greater Boston Area
    (2020-12-21) Helling, Leija
    Documenting racial disparities in the spread of COVID-19 is crucial to bettering public health. In the Boston area, non-white and Black communities are significantly overrepresented in areas of high confirmed COVID-19 prevalence. Areas where high prevalence is clustered (“hot spots”) have disproportionate shares of non-white and Black residents, and the disparities are statistically significant. These results confirm marked COVID-19 racial disparities in Boston.

    Georeferencing the MacConnell Aerial Photo Collection
    (2021-11-17) Heilmann, Alex; Martin, Matthew; Barchers, Camille; Bowlick, Forrest J; Seifried, Rebecca M
    In the 1950s, Professor William P. MacConnell from the University of Massachusetts Forestry Department began working with his students to map the land cover in Massachusetts via the state’s earliest aerial photography program. These individual photographs are now part of the Special Collections and University Archives at the University of Massachusetts Amherst Libraries, and although they have been digitized and made available online, they have not yet been georeferenced. In Spring 2021, our team (Alex and Matthew) began manually georeferencing the photos in ArcMap 10.8 software onto USGS 2019 color orthoimagery of Massachusetts available from MassGIS. Ideal ground control points include building corners, intersections, and any other distinctive features that have not resulted in much change between the historic and contemporary aerial photos. Some challenges we have faced include varying angles in which the photos were taken, cliffs that offset height in parts of the photo, or photos with a heavily forested area that makes georeferencing difficult to pinpoint ground control points. The goal of the project is to georeference the approximately 4,800 individual photos from the 1951-52 series, which spans the entire state of Massachusetts, in order to make them available to the general public as downloadable GeoTIFFs. This result will allow anyone to access the photos and use them to analyze land-use changes in Massachusetts spanning the last 70 years. Manual georeferencing has come with its own challenges when encountering heavily forested aerial photos or aerial photos dominated by mostly urban areas. We find that future research into the potential automation of the georeferencing process would help alleviate the challenges associated with manual georeferencing.
