How GIS started, how it evolved, what was first application of GIS  John Snow’s analysis of the cholera outbreak in London in 1854 was the first ever application of GIS. Cause of disease, was examined spatially and water well were found to be the source of spreading cholera. Although this was all human visualization and interpretation on paper maps, but it is marked as first ever GIS Application .                                                                Happy GIS Day 2016  image source : https://blogs.esri.com

How can farmer benefit from Remote Sensing Satellite Images can be used to study vegetation. Farmer can monitor health using satellite images, Using Satellite Images to calculate NDVI   Normalized Difference Vegetation Index ,  NVI   Normalized Vegetation Indice.  Example of Satellite Sensor : SMOS (Soil Moisture Ocean Salinity), can forecast crop production, depict drought as well. How it works : Near Infrared & Red Band can be used to study vegetation since in NIR band vegetation gives maximum reflection and in Red it gives minimum  Crop Monitoring can help farmers in monitoring their fields by giving them real-time information about possible risks that could threaten their crops image source:  Tata Chemicals
