One of many essential issues of the agricultural producer is having the ability to know, precisely, the tons of harvest that he’s going to receive on his plot. This info is of nice significance for the economic system of the entrepreneur. On the one hand it permits you to quantify your revenue. On the opposite, handle the attainable markets during which you propose to promote the harvested product.
Present harvest gauging programs are based mostly on counts based mostly on subject sampling models. It’s true that they’re fairly proper with actuality, so long as they’re carried out by specialists who’re educated in regards to the particular traits of the crop or plantation in query.
Nonetheless, the usage of new methods to estimate manufacturing, based mostly on the usage of huge information from satellite images and on the Web of Issues (IoT) has turn into a instrument of monumental significance. Their success charges attain up to 95%. Video of the analysis undertaking carried out
How to discover out the manufacturing with satellite images?
Using satellite images, via distant sensing (science that enables acquiring info from any object on the earth’s floor with out coming into contact with it) implies a deep data of the crop or plantation, as well as to the set of reactions that happen within the ambiance and on the bottom. In fact, additionally of the prevailing relationships between every of them.
Figuring out this, and thanks to the usage of the knowledge contained in every of the pixels (within the type of spectral bands) of the satellite picture, a collection of various algorithms are generated. With them, the manufacturing is estimated within the quick, medium and long run so as to receive the utmost adjustment in accordance to the second during which it’s needed to know the manufacturing (Determine 1), be it current, previous or future.
It should be taken under consideration that, to receive an estimate shut to actuality, radiation should be taken under consideration, a variable associated to chlorophyll manufacturing, the scale of the leaf and the fruit, in addition to the extent of evapotranspiration. of the plant, amongst different elements. With out the inclusion of satisfactory radiation, manufacturing shall be underestimated by 15-30%.
Precision agriculture by satellite
Precision agriculture is a technique that enables managing, processing and analyzing, each spatially and temporally, all the knowledge obtained, on the pixel degree, from the agricultural farm. This permits a collection of plot administration choices to be made that permit a rise in effectivity in the usage of assets and, due to this fact, in productiveness, as well as to these elements associated to the standard, profitability and sustainability of the land. agricultural manufacturing.
Cheaper than a drone
With the usage of satellites it’s attainable to have information in a brief time period (between 1 and 5 days), an element that considerably improves the estimation of manufacturing by having a higher quantity of data, decreasing variability and error within the information. outcomes. This is likely one of the benefits over the usage of drones, as well as to the associated fee, since this may differ between 3,000 and 6,000 euros per flight. Regardless of this, so as to complement the satellite info in a well timed method, it’s advisable to perform one or two drone flights each two or three months.
As we speak, the event of know-how based mostly on info from satellites is leading to a rise in decision. This additionally entails a rise when it comes to studying the knowledge per pixel, as a result of the information assortment may be carried out in meshes of 1 x 1 m, Three x Three m or 5 x 5 m, with out counting these utilized by the satellites of very excessive decision (0.2 x 0.2 m to 0.eight x 0.eight m) and priced between $ 274 and $ 400 per sq. kilometer. This leads to a considerable amount of high-quality noticed information, facilitating the excessive precision and reliability of the predictive algorithms of manufacturing on agricultural farms.
