How Satellite Imagery Is Collected and Processed

Satellites used for collecting imagery in precision agriculture orbit the Earth at various altitudes.

They capture images of the land below.

These satellites can be classified based on their altitude, such as low Earth orbit (LEO) or geostationary orbit.

Remote Sensing Technology

Remote sensing technology involves using sensors on satellites to detect and capture data about the Earth’s surface.

These sensors can detect various wavelengths of light.

This capability allows for the creation of different types of images, such as multispectral or hyperspectral.

Geographic Information Systems Integration

Once the satellite imagery is collected, it is processed and analyzed using Geographic Information Systems (GIS) software.

GIS allows for the integration of different data layers, such as soil type, crop health, and weather patterns.

This integration helps create detailed maps that aid farmers in making informed decisions.

Satellite imagery plays a crucial role in precision agriculture by providing farmers with valuable data about their fields.

By utilizing satellites, remote sensing technology, and GIS integration, farmers can optimize their crop management practices.

This optimization leads to improved overall efficiency.
