Summary:On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat satellites have been collecting data using various portions of the visible and invisible electromagnetic spectrum, at a scale close enough to see highways, but not individual buildings on a city block. Assigning different colors to different combinations of wavelengths allows us to see particular patterns more clearly. Geographic Information Systems (GIS) technology allows us to match locations, integrate data, conduct analyses, and show change from place to place or time to time. These tools allow us to monitor vegetation health, such as identifying areas of drought stress or insect damage. We can find changes in land use, such as expansion of urban areas into what was farmland or even desert. Climate change can be seen in the retreat of glaciers, or even shifts in coastlines of low-lying regions. By combining imagery data with other layers of information such as roads, population, or land ownership, GIS allows us to see trends and develop strategies for addressing issues. Geoscientists, foresters, water managers, and others in countless careers use GIS and its integrative nature to study and cope with issues of change. You can, too.
