US: Trimble has announced that it is adding another new agronomic service to its Connected Farm solution. The PurePixel Precision Vegetation Health Solution provides specialized processing of multi-spectral images used for crop health analysis. Field images processed with PurePixel technology provide farmers and advisors with a visual representation of the selected field’s crop health or maturity level based on a colour-coded index. Since PurePixel filters out non-crop artifacts such as soil, shadows, and surface wetness, it can be used on fields with newly emerged vegetation or fields with full crop canopy.
PurePixel produces a vegetation vigour index map, which is a calibrated representation of vegetation health that can be used to track crop growth and measure the magnitude of difference between areas. Because PurePixel maps use a calibrated index, users can compare multiple images of the same area and visually detect changes in crop health over time. This feature is especially useful for monitoring expected progress in crop growth or improvements in crop health when treating underperforming areas within fields.
