What can heritage teach us about climate change, and how we can take action? This online exhibit illustrates the climate change-related impacts, challenges, and opportunities of tourism at UNESCO World Heritage Sites. The tool is designed to inform the general public, educators, policymakers, site managers, and tourists about how the climate crisis is already affecting their lives, how they might be contributing to this crisis, and what can be done to mitigate and adapt to climate change.

"Connecting the Corridor" is a story map that explores the neighborhoods along the route of the Purple Line, a light rail under construction in Maryland. The story map uses photographs, charts, and interactive maps to explore how the historical legacy of racial discrimination continues to shape the region. Purple Line advocates hope that the line, connecting two areas that were intentionally divided by policy, will help foster a more widely-shared economic prosperity and help counter residential segregation.

The extreme disposability of clothing and textiles in contemporary society has reached a critical degree. Around 10 million tons of textile ends up in landfills each year, contributing to water, soil, and atmospheric pollution. Plus, with the ever increasing production of textile, the issue is only growing. In this story map we analyze causes, effects, and possible solutions surrounding this issue.

Lead data from Baltimore, MD is the perfect case study to demonstrate how environmental exposures, and subsequently disparities in health, flowed from policy decisions. Redlining can be understood as a practice in which the Federal Housing Administration rated Black neighborhoods as high risk to prevent people of color from getting mortgages and moving into wealthier, Whiter neighborhoods. Due to these racist policies spanning back to the early 1900s, Black Baltimoreans are more likely to be affected by lead poisoning today.

This project is a continuation of previous research on the oral history of breaking. Breaking is now an Olympic sport and will debut in Paris in 2024. However, there is limited information about the practitioners and scholars of the dance. In the 1990s, dancers released solo travel documentaries, including montages of themselves and other dancers while traveling, then distributed the tapes within a networked community. By mapping the origin of the videotapes, community members and the general public will better understand the spatial relationship between dance styles and how these styles are currently adapted.

This web mapper highlights relative occurrences of environmental hazards and locally unwanted land uses (aka "LULUs") alongside population health outcomes and sociodemographic data to visualize environmental injustice throughout Maryland. The MD EJSCORE model incorporates 22 indicators to produce a percentile ranking for each census tract in Maryland. In 2020, four new functions for screening and visualizing environmental justice indicators were added: the Select Feature and EJScreenChart, Side-by-Side Mapper, Report tool, and Base Map Selector. MD EJSCREEN can be used by local policymakers, regulators, and community leaders in a decision-support capacity to inform strategies for reducing environmental injustice.

The Plant Patent Metadata Portal is a resource created by the University of Maryland Libraries to keep track of US Plant patents. The Libraries, designated by the US Patent and Trademark Office (USPTO) as the College Park Patent & Trademark Resource Center (PTRC), hopes to assist other PTRCs in making color Plant Patent images easily available to browse and search.

To Relate reveals the homelands of Native American Tribes who were Indigenous to Texas and explains their defined relationships to one another. The exhibit features an original video about the National Park Service Historic Trail that goes through Austin, called El Camino Real de los Tejas. The El Camino Real de los Tejas original Native American trail routes developed into roads and highways, travel through cemeteries, parks and golf courses, and are near high schools, fresh water springs, and recreation areas which are actively used today. This project also used advanced GIS imagery and maps to illustrate historical concepts and identify historic Native American village sites in a major metropolitan city.

A story map highlighting the broadcast locations of the radio program Vox Pop, which traveled around the United States interviewing men, women, and children during the Great Depression, the Second World War, and the early post-war period.

This map shows the relationship between average ridership at all the WMATA metro stations and the median household income in those areas, based on Census tracts in the year 2016 (before the world fell apart). Originally, my hypothesis was that areas with lower incomes would have higher ridership levels due to historically being more reliant on public transportation - but I was proven otherwise, as the most popular stations are (expectantly) the commercial hubs of the District such as Metro Center and Farragut North. It's worth noting that outside the realm of these clustered stations, the terminal station of each line has higher ridership than smaller stations along the line. It could be assumed that most people are living outside the metro system and commute to the terminus station, then head into downtown.

Harmful algal blooms are a major environmental problem worldwide. A harmful algal bloom consists of organisms that deplete oxygen in the water killing organisms in marine or fresh waters and potentially causing severe impacts to human health, aquatic ecosystems, and the economy. Blooms can last from a few days to many months. This map illustrates the locations of species that could cause harmful algal blooms worldwide. Each grey dot represents one or more occurrences of the species. The data presented here were collected through a program called HABMAP, a joint initiative of ISSHA (International Society for the Study of Harmful Algae) and the IOC (Intergovernmental Oceanographic Committee) of UNESCO.
