Students wrangle big data during annual symposium

通过maryalice CKM上 - 杰克逊

有个 过多 数据的 out there and growing dem和 for those who can mine it effectively. On May 6, 16 students showed them how it’s done during the 地理信息系统 (geographic information system) Exhibition 和 Poster Session, an annual event showcasing the ways students apply powerful technology to recent or ongoing research.

“It’s a reasonably complicated computer program to learn, but it’s definitely worth the learning curve,” said Jill Hautaniemi '14 of the software, which provides a framework to store 和 analyze geographically based data.

Mapping near 和 far

该 students, all part of an advanced GIS-applications course led by 地理信息系统 Specialist James Ciarrocca, presented data that had been recently gathered in points near 和 far. A 双主修 环境的 科学生物学, Hautaniemi cross-referenced data she’d collected for her senior 生物学-research project with elevation data sets from a government Web site, and found correlations between elevation levels 和 the health of hemlock trees in the Carlisle region.

Jenna LaRiviere ’14, an 考古学 大,结婚 historical and construction data about barns in Pennsylvania with the geological makeup of the ground on which each barn stood. “By integrating location with foundational materials, we can get insights about the economic, political and practical reasons why they chose these materials, and this tells us something about the people who lived there,” says LaRiviere, who will pursue a master’s in museum studies at the University of East Anglia in the fall. “It adds a whole new dimension to our underst和ing of their histories.”

Environmental 科学 major Jack Bryan ’14 examined stream-remediation options in nearby Michaux State Forest, using raw data collected by the Pennsylvania Department of Conservation and Natural Resources and by students in a conservation seminar. By creating elevation and relief profiles of the watersheds, he was able to identify the areas most in need of cleanup, 和 he’ll make the project available to stream-monitoring volunteers.

“Hopefully, they’ll build on this, and as they do, they’ll be able to recognize patterns and use different variables in t和em, combining data they might not think to combine,” Bryan said.

Taylor Thompson ’14 presented student-faculty research on the effects of temperature on sex determination in 锦龟 born in 2010 at a local pond. She inputted temperatures recorded at 16 turtle sites with the precise locations of each nest, the makeup of the soil on which they rested and the sex of the turtles born there. Nests built on natural soil, which stabilizes slight temperature fluctuations, yielded a roughly even number of male 和 female turtles, whereas nests built on a soil-gravel mix did not. “Because the information is displayed spatially, you can 看到 the patterns emerging,” she said. 

Other locally based projects included Michael D’Aprix ’14’s geodatabase for Dickinson’s campus, Anna McGinn '14’s produce-access map of the Carlisle area, Anne Dyroff ’14’s qualitative map of Carlisle running routes, Mary DiGiorgio ’14’s analysis of campus trees 和 Christine Burns ’14’s study of trees in downtown Harrisburg.

Projects rooted farther from home included a crime-rate analysis of North Philadelphia (Amanda Vandenburg ’14), a basin analysis of a state park in Maine (Elizabeth de la Reguera ’14) and a trail map of Michaux State Forest (Tucker Deady ’14). Will Kochtitzky ’16, Aleksander Perpalaj'14 and Leslie Milliman ’14 went global. Kochtitzky created a map of lake vegetation in Bolivia, Perpalaj mapped a sub-glacial volcanic ridge in Iceland and Milliman presented visual data about weathering on an isl和 in Guadeloupe.

“It’s amazing how many different applications there are, as you can 看到 in the variety of subjects represented here,” said Thompson, an 环境的 studies major who plans to apply 地理信息系统 technology to her analysis of trail connectivity as part of her job with the Doylestown Heritage Conservancy, which begins after her graduation in May.

“And we’re just scratching the surface,” added Bryan. “It’s essential to know how to apply basic skills in new contexts. And this is an incredibly useful 和 powerful tool.”
