REMOTE SENSING AND GIS IN PRECISION AGRICULTURE: A REVIEW OF CROP MONITORING AND GUIDANCE

Remote Sensing and Geographic Information System technologies have emerged as a key component for precision agriculture as it provides accurate, timely, and large-scale information for crop monitoring and farm management. The GIS and Remote Sensing system enable us to continuously monitor the development of crop, the state of soil, the variation of moisture, and the health of the plant on the basis of the satellite images, UAV data, and measurements on the sensors. It is now that farmers and agricultural planners can easily evaluate the field condition and make their decision due to expansion of satellite missions and increased spatial and temporal resolution. GIS complements the ability of system to organize, integrate, and visualize the multi-source spatial data in a map that helps in crop choice, irrigation programming, fertilizer planning, and estimation of yield.
