What is Crop Insight and how does it work?
The Proof of Concept (PoC) for this platform presents an innovative solution designed to empower farmers with advanced agricultural insights directly from their desktops or mobile devices. This platform integrates seamlessly with Google Maps, allowing users to select any agricultural field or area of interest with precision. Utilizing the Google Maps API, it enables the creation and interaction with a map interface, providing functionalities such as display customization, layer manipulation, and user interaction personalization.
Key to its utility is the integration of the Google Maps Drawing Library, which facilitates the selection of specific land plots by enabling users to draw polygonal areas that represent their chosen fields. This feature is instrumental in narrowing down the exact location for analysis, ensuring that the satellite imagery and agricultural indices fetched are highly relevant and accurate.
The platform uses the Sentinel Hub API to fetch detailed satellite imagery and a comprehensive suite of agricultural indices for the selected areas. These indices include:
- NDVI (Normalized Difference Vegetation Index)
- EVI (Enhanced Vegetation Index)
- Barren Soil Index
- Moisture Index
- Moisture Stress Index
- Agriculture Index
- SAVI (Soil-Adjusted Vegetation Index)
These indices provide vital information on vegetation health, soil condition, and moisture levels, among other agricultural parameters, enabling farmers to make informed decisions about their land and crops. The Sentinel Hub API also allows users to select specific time frames for the satellite imagery, offering temporal flexibility to monitor changes and trends over time.
To ensure that the platform remains user-friendly and intuitive, it utilizes the Vanilla.js framework, known for its capability to facilitate the rapid development of simple yet powerful user interfaces. This choice underscores the platform’s commitment to providing a seamless and accessible user experience, enabling farmers and agricultural professionals to leverage cutting-edge satellite technology with ease.
This PoC represents a significant step forward in agricultural technology, offering a tool that not only simplifies the process of land and crop analysis but also enhances the decision-making capabilities of its users through precise, data-driven insights.
The website described allows users to select land parcels using Google Maps, view satellite imagery, and access various agricultural indexes. This functionality is supported by integrating several key technologies:

Understanding agricultural indexes is crucial for farmers to optimize crop health, yield, and overall farm management. Here’s a detailed look at the indexes mentioned and how farmers can benefit from them throughout the year and across different seasons:
NDVI (Normalized Difference Vegetation Index)
NDVI measures the difference between near-infrared (which vegetation strongly reflects) and red light (which vegetation absorbs) to assess vegetation density and condition.
It helps in monitoring crop health, estimating biomass, and predicting yield. Throughout the year, NDVI can guide irrigation, fertilization, and harvesting decisions by indicating plant stress before it’s visible to the eye.
EVI (Enhanced Vegetation Index)
EVI corrects for some atmospheric conditions and canopy background signals, providing more sensitive measurements of vegetation cover, chlorophyll content, and biomass than NDVI, especially in high biomass areas.
It’s particularly useful for ensuring optimal plant growth and health, especially in densely vegetated areas. EVI can aid in adjusting crop management practices to improve yield.
Barren Soil Index
This index identifies areas of bare soil, helping in the assessment of land use and management, including erosion risk and previously uncultivated lands.
Knowing the extent of barren soil can help in soil conservation efforts, identifying areas for potential cultivation, and monitoring the effectiveness of soil management practices.
Moisture Index
Moisture indexes assess the water content in soil and vegetation. They are crucial for determining drought stress and optimal watering levels.
Throughout the year, especially in varying seasons, these indexes help in managing irrigation more effectively, reducing water waste, and ensuring crops are not over or under-watered.
Moisture Stress Index
This index specifically measures the stress level of plants due to insufficient moisture, indicating potential drought conditions.
Early identification of moisture stress allows for timely irrigation adjustments, potentially saving crops from drought-induced damage and improving water resource management.
Agriculture Index
This broad index encompasses various factors relevant to agriculture, including vegetation health and soil quality, to provide an overall assessment of agricultural land productivity.
By assessing the productivity of their lands, farmers can make informed decisions about crop rotation, land resting, and other practices to enhance soil health and crop yields over time.
SAVI (Soil-Adjusted Vegetation Index)
SAVI adjusts NDVI for the influence of soil brightness, particularly useful in areas with sparse vegetation where the soil significantly affects the measurement of vegetation health. It offers more accurate information for making farming decisions in semi-arid regions or where the land cover is not densely vegetated, aiding in the detection of subtle changes in plant health.
How Farmers Benefit Year-Round and Across Seasons
- Spring. Early detection of vegetation health and soil moisture can guide planting decisions and initial watering schedules.
- Summer. Monitoring crop health and moisture levels helps manage irrigation precisely, optimizing water use during peak growth phases.
- Autumn. Insights into vegetation health and soil conditions can inform harvest timing and post-harvest management practices, like stubble retention to improve soil moisture.
- Winter. Assessment of barren soil and land productivity aids in planning for the next planting season, including decisions on crop rotation and land restoration efforts.
Armed with data from these indexes, farmers can tailor their agricultural practices to the specific needs of their crops and local conditions, enhancing sustainability, efficiency, and productivity throughout the agricultural cycle.
