What is median filtering in image processing?
The median filter is a non-linear digital filtering technique, often used to remove noise from an image or signal. Such noise reduction is a typical pre-processing step to improve the results of later processing (for example, edge detection on an image).
What is digital image interpretation in remote sensing?
Image interpretation in remote sensing is the examination of images, acquired by sensors using different portions of the electromagnetic spectrum, for the purpose of identifying objects and judging their significance. Multi spectral satellite images are used for better interpretation.
Satellite Data Products
Let’s start with the one we all know, Google. Google has compiled what is likely the largest publicly accessible database of satellite imagery in the world (of course, governments all have their own databases as well) and has made these data available and usable through Google Earth, Google Maps, and Google Earth Engine.
What is Satellite Imagery Data?
Not all satellites (and their subsequent image data) are created equal. Various companies (and governments) that operate satellites have different purposes for the satellites and the data they create becomes available at different spatial resolutions, and time scales.
Using Satellite Imagery for Remote Sensing
Capturing images and spectral light measurements from space can be quite useful as a standalone product, but these data become incredibly powerful when they are combined with on the ground monitoring points.
Harnessing the Power of Space
Remote sensing and satellite imagery data are being used around the globe by the agricultural industry to make decisions, understand changes, and estimate future conditions.

What is satellite imagery data?
Satellites and the images they produce differ from each other, as different companies use them for various purposes. Satellite data is a collection of millions of pixels that are related to distance on Earth. The result is images with different resolutions and time scales. A pixel can display an area from 30 m2 to 1 km2 or even more.
Ways how agriculture satellite imagery changes agriculture and farming
Sustainable resource management is a necessity today. Remote sensing satellites are contributing to more sustainable water use on farms. Satellite data helps to avoid over or under irrigation, improves the quality of agricultural products, and helps to increase yields.
Satellite imagery significantly expands the capabilities of farmers and other participants in agribusiness. Technology continues to evolve and improve, allowing you to capture images of the best quality.
What is satellite imagery?
Satellite imagery. Satellites are one of the most used means in agriculture to perform remote sensing. The satellite imagery in fact allows to monitor crops remotely in a precise and efficient way.
Which satellites have multispectral images?
There are many satellites that acquire multispectral images from space: the most common are Sentinel-2 and Landsat 8 (both used in Agricolus platform ), Airbus Spot 6 and Pléiades (test phase). The images obtained have a spatial resolution of a few meters: Landsat 8 provides data with a spatial resolution of 30 m, while Sentinel-2 of 10, …
How often is Landsat 8 available?
The temporal resolution is in most cases regular. For example, Landsat 8 is available every 16 days, while Sentinel-2 is available every 3/5 days (depending on the zone). Airbus Spot 6 and Pléiades are on demand according to the needs.
Why is it necessary to introduce the concept of vegetation index?
When talking about satellite images, and remote sensing in general, it is necessary to introduce the concept of vegetation index to understand how they allow the monitoring of the health of crops without the need to go to the field.
