The images in high definition allow the user to view the vegetation indexes with a resolution that is almost 10 times better than standard images and as frequently as every 2 days depending on the climate factors.
The resolution of the images in high definition is 3 x 3 m per pixel (9m2). From these, it is possible to analyse fields more accurately and to identify variability in situations adjusted to the type of crop or the scale of field work required.
Frequency of Images
The images are displayed very frequently, almost daily, which allows the user to have more information about the crops in important and critical periods, where the capturing and registering of information becomes key to generating maps of production zones, predicting yields or detecting problems that may be affecting the crop.
In practice, high-definition images make it possible to detect and monitor weed outbreaks in fallow land, accurately define areas that have been flooded due to climatic events, analyse fertilisation practices or crops of different varieties, and much more.
By definition, Auravant´s functions generate value from the images available. Therefore, the high-resolution images enhance the tools of the web platform and the mobile app. Some examples are the definition and accuracy when defining environments and prescriptions as well as the number of images available that can be included in the reports.
The images have spectral bands in red, green, blue and infrared. And so, it is possible to view the vegetation indexes that are obtained from equations involving these bands, such as, NDVI, GNDVI and MSAVI2.
