Thermal imaging can be used in all fields where temperature differences help analyse an area or an object. It is a relatively new technology in agriculture, but it is quickly gaining popularity. As the cost of thermal cameras continues to decrease, and as more farmers become aware of the benefits of thermal imaging, it is likely to become an essential tool for many farmers in the future. When used in agriculture, it helps a lot in plant disease detection, yield estimation, evaluating the maturity of the crop, water stress estimation, irrigation scheduling, as well as fertilization planning. Currently, there is not much work being done in the field of combining thermal and multispectral images through machine learning. However, the fact is that by using both technologies, more comprehensive data can be obtained, and potential errors that may arise from using only one technology can be identified. Nevertheless, for more complex research, both thermal and multispectral imaging are used seamlessly, and the gathered information, especially for thermal, is processed manually.
Variable rate application (VRA) maps without guided navigation system
Variable rate application (VRA) maps can still be useful even without navigation, depending on the specific context and goals of their use. VRA maps are designed to guide agricultural machinery, such as tractors or sprayers, in applying inputs (e.g., fertilizers, pesticides) at variable rates across a field. The purpose is to optimize the use of resources and inputs based on the variability of soil and crop conditions within the field. There are cases where VRA maps can be useful even without guided navigation: Pre-Planning: Farmers and agronomists can create VRA maps based on historical data, soil sampling, satellite imagery, or drone surveys. These maps help determine the optimal application rates for different areas of the field before actual application begins. Manual Application: In situations where navigation systems are not available or practical, farmers can manually follow VRA maps’ guidelines to apply inputs at varying rates using their knowledge and experience. Small-Scale Operations: For smaller farms or areas where the use of GPS-based navigation systems is not feasible or economical, VRA maps can be used to guide manual variable-rate application. Non-Precision Applications: Some agricultural machinery may not have advanced navigation capabilities, but they can still make use of VRA maps to adjust input rates manually as they move across the field. Research and Analysis: VRA maps can be utilized in research studies and data analysis to assess the effectiveness of variable-rate applications and identify trends or patterns in field variability. However, it’s essential to note that while VRA maps without navigation can provide benefits, the full potential of variable-rate application is realized when it is combined with precision agriculture technologies, including GPS-guided navigation. Navigation systems enable real-time adjustments and ensure precise execution of VRA prescriptions, maximizing efficiency, and minimizing input waste. As technology continues to advance, integrating navigation capabilities with VRA maps is becoming more accessible and cost-effective, enabling farmers to achieve greater precision and efficiency in their agricultural practices.
What is greenseeker sensor
The GreenSeeker sensor is an agricultural technology device used to optimize the application of fertilizers in crop fields. It measures the variability of crop vigor or “greenness” within a field and provides real-time data to help farmers make informed decisions about fertilizer application rates. The GreenSeeker sensor operates based on the principle that plants reflect and absorb light differently depending on their health and nutrient status. It emits light in the near-infrared (NIR) spectrum and measures the amount of reflected light. By analyzing the reflected light, the sensor can assess the overall health and vigor of the crops. Farmers typically mount the GreenSeeker sensor on a tractor or other farm equipment and drive it through the fields. As the sensor moves, it collects data on the crop’s reflectance and transmits it to a computer or handheld device for analysis. The data is then used to create a vegetation index, such as the normalized difference vegetation index (NDVI), which quantifies the level of crop vigor. By mapping the variability of crop vigor across the field, farmers can identify areas that require more or less fertilizer. This allows for site-specific fertilization, where the application rates can be adjusted according to the specific needs of different parts of the field. It helps optimize fertilizer usage, reduce costs, and minimize environmental impacts by avoiding excessive fertilizer application. Overall, the GreenSeeker sensor is a valuable tool for precision agriculture, enabling farmers to make data-driven decisions and improve resource efficiency in their crop production.
How tractors use prescription maps

Why are reflectance panels must have for multispectral drone operators
A multispectral reflectance panel, also known as a reflectance calibration target or color calibration target, is a specialized tool used in remote sensing and imaging applications. It is designed to have known and stable reflectance properties across multiple spectral bands or wavelengths. The panel consists of a flat surface divided into several patches, each with a different known reflectance value. These reflectance values are typically measured or calibrated using a spectrometer or other specialized instruments. Multispectral reflectance panels are used to calibrate remote sensing instruments, such as satellites or airborne sensors, to ensure accurate and consistent measurements of the Earth’s surface. By imaging the panel under controlled conditions, the instrument can compare the measured reflectance values of the panel’s patches to their known values. This allows for adjustments and calibration of the instrument’s measurements, compensating for any variations or biases. The panels are often constructed to have high reflectance uniformity and stability over time. They can be made using various materials, such as specially designed paints, ceramics, or polymers, depending on the spectral range of interest. Multispectral reflectance panels are crucial for maintaining the accuracy and reliability of remote sensing data, enabling researchers to compare and analyze images acquired at different times or from different sensors. They play a vital role in applications such as environmental monitoring, agriculture, land cover mapping, and scientific research.
