Researchers use GPS to collect geotagged air quality data at street, neighborhood, and regional levels. Mobile stations equipped with both GPS receivers and air sensors, like the Aeroqual Series 500 paired with Garmin GLO 2, capture PM2.5 or ozone concentrations with precise coordinates. Many air monitoring apps log spatial location automatically, ensuring pollutants get mapped to exact spots. I use GPS when scouting wildfire smoke impact zones, which lets me compare readings across repeated visits and detect changes over time.
Water Resource Management
Teams rely on GPS for tracking and recording the locations of water sampling, stream gauges, and pollution sources in watersheds. Devices such as the Trimble Geo 7X make it possible to revisit identical sample sites season after season, cutting errors and improving trend analysis. Municipal water departments tie GPS-tagged monitoring stations to asset management maps for leak detection or regulatory reporting. When mapping riverbanks or reservoir perimeters during droughts or floods, my GPS mapping experience ensures change measurements stay accurate.
Wildlife and Habitat Tracking
Biologists fit animals—including elk, sea turtles, and migratory birds—with GPS collars or tags to record movement and migration routes. Devices like the Lotek Iridium GPS collar or the Garmin Alpha 200i provide frequent, timestamped fixes, which help habitat managers identify breeding grounds, travel corridors, and threats. In conservation, field teams equipped with handheld GPS receivers log sightings, nest locations, and boundaries—the same way I log trail markers on backcountry hunts. Consistent coordinates across seasons make impact assessment and recovery planning more precise.
