The identification of bare fallow by ground-based spectrometry and satellite data

The purpose of the study is to develop the method for detecting bare fallows by ground-based remote and satellite data during growing season of 2018. The objects of the study are bare fallows and wheat crops on the territory of the Krasnoyarsk RIA FRC KSC SB RAS near the village of Minino (Krasnoyarsk Territory). When conducting ground- based spectrometry of the test sites studied, a field- based spectrometry complex was used, consisting of Spectral Evolution PSR-1100F portable spectroradiometer, a computer, a calibration reflect- ing standard, a digital camera, and software. As a result of ground-based spectrometry, reflective spectral properties of bare fallows and wheat crops were studied, which are commonly expressed by spectral brightness coefficient (SBC). The spectral brightness coefficient of objects in the range from 320 to 1100 nm was measured. Sentinel-2B satel- lite information was used to interpret bare fallows and wheat crops. On the basis of ground and satel- lite data the spectral indices were calculated: NDVI(Normalized Difference Vegetation Index) and NDSI (Normalized Difference Soil Index)...
