Satellite Imagery Applications

Satellite imagery has transformed geography-dependent fields. Archaeologists use multispectral imaging to detect buried structures invisible to the naked eye through vegetation growth patterns.

In agriculture, satellites monitor crop health by analyzing reflected light wavelengths. Stressed crops reflect different infrared signatures, allowing targeted irrigation that saves billions of liters annually.

Deforestation monitoring relies almost entirely on satellites. Brazil's DETER system detects illegal clearing within days. Environmental groups use free Landsat data to hold governments accountable for forest commitments.
