Landsatsatellieten

Landsat is a series of Earth-observing satellites operated by the United States Geological Survey (USGS) and NASA. The program began in 1972 with the launch of Landsat 1, making it the longest continuously operating system for acquiring satellite imagery of Earth. The primary goal of the Landsat program is to provide reliable, long-term data on land cover, land use, and environmental changes across the globe.

Each Landsat satellite carries an array of sensors that capture data in various spectral bands, ranging from visible light to infrared and thermal wavelengths. This multi-spectral data allows scientists to differentiate between different types of vegetation, soil, water, and man-made structures. Over time, the Landsat program has evolved with technological advancements, with each subsequent satellite offering improved resolution, spectral capabilities, and data acquisition efficiency.

The data collected by Landsat satellites has a wide range of applications. It is crucial for monitoring deforestation, agricultural productivity, urban sprawl, water resource management, and natural disaster assessment. Researchers and policymakers worldwide utilize Landsat imagery to understand global environmental changes and inform decision-making. The historical archive of Landsat data is publicly accessible, providing an invaluable resource for studying long-term trends and patterns of Earth's surface. The program continues with ongoing missions, ensuring a consistent stream of data for future generations.
