3.5 Tiny Bytes: Landsat vs Sentinel for NDVI and Variable-Rate Maps
About this episode
This episode explores the use of Landsat and Sentinel satellite imagery for NDVI analysis and variable rate mapping in agriculture.
We take a practical trip into satellite imagery and explain how Landsat and Sentinel support real agronomy work like NDVI analysis and variable rate mapping. We break down what makes these datasets reliable, how resolution changes what you can see, and why revisit timing matters when clouds get in the way. In this episode, we tackle: • free government-operated imagery through NASA USGS and the European Space Agency • using multi-band satellite data to calculate NDVI for crop vig...
