Our goal is to map and measure historic apple trees in Boulder to find the varieties that were planted as part of Boulder’s unique apple industry in the early 1900s. Undergraduate computer science students built the interactive map to display tree locations and a mobile phone app designed for collecting and visualizing data in real time. This paper is a case study that focuses on curricular and extracurricular engagement of undergraduate students, application design, and the contributions of these efforts to the scientific community.
