I developed a skills training session, Participatory Mapping and GIS for Community Health, for residents in the Brown Family Medicine Residency at Memorial Hospital of Rhode Island in August 2017. Download the training module here: http://www.josephholler.com/files/PGISHealth.pdf
We opened the session by discussing the utility of participatory mapping for community health assessment and planning healthy communities. We then played the roles of both researchers and research participants: we planned and implemented participatory mapping to solve the problem of elderly pedestrian mobility in the environment immediately surrounding Memorial Hospital. We brainstormed features to look for, planned a data collection schema, implemented the schema in a mobile app, and collected data around the hospital!
This activity used more free GIS data and software than open source, drawing from RIGIS and USGS for base map data, Avenza Maps for data collection, and Google Earth Pro and Google My Maps for data visualization.
