NEW DELHI, August 7, 2018/PRNewswire/ --
India's leading climate risk management company, Weather Risk Management Services Pvt. Ltd., leverages Remote sensing and Geographic Information System (GIS) technologies for real-time analysis and forecasts of weather, floods and monitoring crop area sown, lost or damaged due to floods and rainfall.
Agriculture is one of the major sectors in Indian economy. India being a world's largest producer of rice, wheat and pulses, must keep up its pace with growing digital technologies. Over the past few decades, Remote Sensing & GIS has grown exponentially in many sectors for visualization, monitoring, management and potential development. Remote Sensing & GIS technology enables agencies to get reliable information of natural and man-made features, or processed and interpreted appropriately phenomenon occurring over the earth's surface without making any physical contact. Nowadays, farmers rely on these technological improvements. Brief descriptions of Remote Sensing services provided by WRMS are given below.
Crop Sown Area Estimation: Crop sown area estimation is one of the major sections in agriculture Remote Sensing activities, which is done for entire country. Remote Sensing play a crucial role in mapping and monitoring of various crops sown area estimation.
Satellite data such as Sentinel-1, 2, Landsat-8, World View-3, LISS-IV and more provide precise level crop sown area and helps in crop loss assessment due to various catastrophic disasters. WRMS estimates the crops and vegetables sown area of paddy, cotton, wheat, pulses, potato, peas and more.
NDVI (Normalized Difference Vegetation Index): This is primarily used for the assessment of vegetation dynamics, particularly in determining the crop health status. With NDVI, the possibility of understanding the crop phenology escalates as it explains the crop chronology and their relationship with weather and climate (season). NDVI is measured using mathematical calculation of spectral bands within the satellite image which measures healthiness of vegetation, as it has a robust correlation with green biomass indicating a healthy vegetation or crop.
Crop Diseases Identification: Remote Sensing technology provides spatially distribution of information of diseases and pests over a large area with relatively low cost. With the help of satellite imagery and spatial analysis techniques, crop infected areas are identified like Mealybug, Plant Hopper, and White Fly to get an overview for evaluating the potentially infected areas.
Soil Properties: Soil properties are crucial in farm management practices as it has direct impact on the yield output. Change in farming system and land management results in soil change which compromises the current and future capacity for primary production and provision of crops and by Micro Nutrition's mapping as soil is a very important aspect of agriculture with characteristics like soil pH, soil organic matter, soil texture, etc. These characteristics infer information about soil condition by observing what happens on the surface in terms of vegetation growth. On the other hand, water content available within the soil is a very important factor that is taken into consideration by soil moisture mapping.
