A cell phone picture has three primary bands (red, green, and blue) that recreate what the human eye sees. But, what if you want or need to see more? Hyperspectral imaging (HSI) uses thousands of specific bands (think hundreds of different segments of blue, green, red, and even going beyond the visible spectrum!) to pick up the unique...

Tight profit margins are nothing new to growers. Fertilizers and crop protection chemicals can amount to up to half of seasonal expenses in large-scale agribusinesses. Crop losses due to disease and pests can take another big bite out of yield. And, with a large portion of budgets tied up in fixed costs, remote sensing applications in precision... Read More >
