Satellite Imagery: Boats in Bay of Naples

This image shows maritime traffic in the Bay of Naples over several years, taken by the radar satellites from ESA’s SENTINEL-1 mission. These two satellites are providing radar images night and day. The image was created by compiling hundreds of by radar images into a…

Satellite Imagery: Antarctic Sunset

The below image is taken from ESA’s SENTINEL-3B.    The line of light and dark is the line between day and night. This picture was taken by the satellite’s ocean and land color instrument, with a resolution of 300m, 21 distinct bands, and a swath…

Satellite Imagery: Falkland Islands

The image below is of the Falkland Islands, taken by ESA’s SENTINEL-1. The images were taken, via radar, on two separate dates a month apart  – December 2019 and January 2020. The combined images show changes over time. The main visible are in the open…

Commodities: Solutions to Predicting Crop Yields

Commodities: Crop Predictions Challenges The challenges of predicting crop yields are significant, as outlined in the previous article. Traditionally these challenges result in low accuracy rates -  below 50%, for certain crops.  This article will look at how the accuracy rate can be increased to...

Satellites: Revisit time

Revisit to detect a change - How long do I have to wait for an image and often can I have an update? While a single image may contain a lot of information, many times we want to detect a change and hence we need...

Open Grain Storage: Measuring Commodoties

Understanding and predicting commodity supply requires a wide variety of data points and an understanding of what is stored and where. Using satellite data it is possible to calculate the yield of crops, location and storage volume of commodities (e.g grain, sugar, wheat) and even...

Satelite Imagery: Chlorophyll and Spring

The below animation, created by ESA with data from SENTINEL-3, shows the changing Chlorophyll around the world between early April and late June 2017. Tropical Rainforests: These hardly change as they keep their high levels of Chlorophyll. USA: The arrival of spring can be clearly…
