With advances in sensing systems attempts are continuously being made to design Internet of Things (IoT) based interoperable systems. The important issues (water, pest/disease, nutrient management, etc.) pertaining crop-weather-soil continuum can be addressed through high resolution monitoring agro-meteorological parameters. Presently the designed have syntactic and semantic heterogeneity face underlying limitations for achieving interoperability among these distributed In this study an...
Abstract. Spatio-temporal crop phenological information helps in understanding trends food supply, planning of seed/fertilizer inputs, etc. a region. Rice is one the major sources for many regions world especially monsoon Asia and accounts more than 11 % global cropland. Accurate, on-time early on spatial distribution rice would be useful stakeholders (cultivators, fertilizer/pesticide manufacturers agriculture extension agencies) to effectively plan supply market activities. Also,...
Natural calamities triggered by erratic weather conditions like cyclone, earthquakes, hail storms, and flood incurs substantial loss to the infrastructure crops of region. Countries across globe are prone such natural calamities. In India, specifically coastal parts vulnerable tropical cyclones. 2018 east coast districts Tamil Nadu Andhra Pradesh, India were affected three cyclones namely Titli (11 Oct. 2018), Gaja (16 Nov. 2018) Pethai (17 Dec. causing severe damage seasonal as Rice,...
Abstract. The current study focuses on the estimation of cloud-free Normalized Difference Vegetation Index (NDVI) using Synthetic Aperture Radar (SAR) observations obtained from Sentinel-1 (A and B) sensor. South-West Summer Monsoon over Indian sub-continent lasts for four months (mid-June to mid-October). During this time, optical remote sensing are affected by dense cloud cover. Therefore, there is a need methodology estimate state vegetation during crops considered in Paddy (Rice) Punjab...
Crop water stress is one of the major factors limiting crop productivity. Maize (Corn) very sensitive to stress. Efficient monitoring and detection crucial for precision irrigation sustainable agriculture. The main objective this study detect during grain-fill stage in maize crops using hyperspectral (HS) observations. hybrid field trial plots were selected from Hyderabad region, Telangana, India. HS images area collected a hexacopter drone mounted with line scanning camera having spectral...
The Traffic problems are a critical problem that influences the travel time of vehicles. road conditions affecting smooth movement vehicles increases traffic issue also unorganized flow, no dividers, steep curves, etc. gives birth to accidents. Lack information shortest path affects emergency vehicle routing. Although calamities, accidents or casualties subject factors cannot be predetermined, an precautionary measures can play crucial role avoid same. aim this work is develop GIS based...
Synthetic aperture radar (SAR) remote sensing has been widely used for crop monitoring due to its high-resolution imaging and all-weather data acquisition capabilities.

Spatio-temporal root zone soil moisture (STRZSM) plays a vital role in the understanding of land-surface dynamics, climate change, soil-water-balance, hydrologic processes, vegetation growth and yield modeling. STRZSM trails can be captured using remote sensing, in-situ or ground based measurements through land surface models. Apart from this, new generation low-cost sensors present cost effective way measurement moisture, but suffer inherent heterogeneity between sensing techniques,...
