(105,000 ha) were classified using Breiman’s random forest classifier, labeled with help of forest enterprise data. In nine test cases, variations of Sentinel-1 and Sentinel-2 imagery were passed to the classifier to evaluate their respective contributions. By solely using a high number of ...
By using band combinations, we can extract specific information from an image. For example, there areband combinationsthat highlight geologic, agricultural, or vegetation features in an image. If you want to see Sentinel band combinations for yourself, you can check out theSentinel Playground. It ...
This example shows agricultural fields in various Sentinel-2 band combinations: Natural Color (left) displays the optical wavelengths our eyes naturally detect, Short Wave Infrared Vegetation (Middle) showing the most vigorous vegetation in bright green, and a Water Moisture Index (Right) with the h...
In order to assess the advantages of combining optical and SAR data, and the importance of each band, the approach was tested separately on three data combinations (S1, S2 and S1+S2) and feature importance was computed to evaluate the contribution of each input layer. The multi-class F-...

To account for the spectral and spatial characteristics of the Sentinel-2 data, we designed criteria for selecting training samples and compared different band combinations. Three strategies for band combination were used: (1) green, red, and near infrared (NIR) bands at 10 m resolution (i.e....
After you download Sentinel satellite data, chances are that you are going to want to display it in the visible spectrum. This is exactly how our eyes see objects around us. Each image is separated by its respective spectral band. See our table above for the spectral bands of Sentinel 2....

Optical VIs are defined as combinations of values measured at different spectral bands, being NDVI (Normalised Difference VI) the most widely used (Bannari et al., 1995, Haboudane et al., 2004). Equivalently, there exists a set of vegetation indices defined on the basis of radar data, ...
