GIS in Action 2026

This map leverages remote sensing data to analyze the relationship between land surface temperature and transit walksheds in Portland. Using Landsat-derived land surface temperature data, the project identifies significant urban heat island patterns along the East Stark Street corridor.

The analysis reveals that some of East County’s most critical transit-accessible resources—including public libraries and schools—are located within areas experiencing the highest surface temperatures. By spatially intersecting heat data with pedestrian access zones, this work highlights inequities in thermal safety for transit-dependent populations.

This project demonstrates how integrating remote sensing with transit accessibility analysis can support more equitable and climate-responsive planning. The findings underscore the need for targeted interventions—such as shade infrastructure, streetscape improvements, community involvement and land use strategies—to mitigate heat exposure along key transit corridors.
