Technological development for agricultural insurance has been the use of remote imaging for damage assessments. Geospatial tools such as satellite imagery are increasingly being used to reduce the time providers spend in-field, giving them data on a claim before they even reach the farm in question. Furthermore, there’s an opportunity for AIPs to go beyond satellite technology by combining it with high resolution aerial imagery coupled with insights powered by AI, bringing improved accuracy and speed to today’s in-person damage assessment methods.

The Solar Induced Chlorophyll Fluorescence-based crop monitoring method mostly addresses crop physiological changes. This method delivers information to the user from a perspective relating to the crop’s biophysical activities than biochemical changes. Solar Induced Chlorophyll Fluorescence is an electromagnetic signal re-emitted by Chlorophyll-a of a plant which was absorbed by chlorophyll-a and chlorophyll-b from active photosynthetic radiation but unused for photosynthesis.

Have you ever wondered why we need so many types of sensors in remote sensing? Visible light, near-infrared (NIR), thermal, panchromatic, and now—SWIR, the Shortwave Infrared band! Today, we’ll uncover the secrets of SWIR sensors and why they’re game-changers in the world of remote sensing. Stick around as we compare SWIR sensors with others, explore their amazing applications, and highlight their advantages. Let’s dive in!
Why does NDVI, NDBI, NDWI Ranges From -1 to 1?

Have you ever wondered how scientists monitor Earth's diverse landscapes from space? They utilize powerful tools like NDVI, NDBI, and NDWI to interpret satellite imagery. But what do these indices mean, and why do their values range from -1 to 1? Let's explore! The Normalized Difference Vegetation Index, or NDVI, is a key indicator used to assess vegetation health. It's calculated using the formula: NDVI = (NIR - Red) / (NIR + Red) Here, 'NIR' represents the reflectance in the near-infrared spectrum, and 'Red' denotes the reflectance in the red spectrum. Healthy vegetation absorbs most visible light, especially red, and reflects a significant portion of near-infrared light. This contrast results in higher NDVI values, indicating robust plant life. Next, we have the Normalized Difference Built-up Index, or NDBI, which helps identify urban and built-up areas. It's computed as: NDBI = (SWIR - NIR) / (SWIR + NIR) 'SWIR' stands for short-wave infrared reflectance. Built-up regions reflect more SWIR and less NIR, leading to positive NDBI values. Conversely, natural surfaces like vegetation reflect more NIR, resulting in negative NDBI values. Lastly, the Normalized Difference Water Index, or NDWI, is designed to highlight water bodies. It's calculated using: NDWI = (Green - NIR) / (Green + NIR) Water features absorb NIR light and reflect green light, resulting in positive NDWI values. Land areas, on the other hand, typically yield zero or negative values.
