What is an aerial photograph and a satellite imagery?
Aerial images and satellite images are two types of photos that are taken from a vantage point above the ground…but that’s about where the similarities end. Simply put, satellite images generally cover a much wider area and therefore have larger scale scientific applications.

How are historical satellite images used in agriculture?
Agriculture is currently one of the industries leveraging the power of historical satellite images to the crop growers’ benefit. Access to old satellite images of fields collected during the past growing seasons allows to generate NDVI time series and observe the crop growth dynamics, identify growth trends and predict future yields.
