1. Geographical Positioning System (GPS)
GPS has now become a handy technology. It opens access to opportunities for spatial data.

2. Geographical Information System (GIS)
Futuristic agriculture will be data-driven. In Digital farming, GIS helps farmers manage and analyze spatial data associated with crop productivity and others. Farmers can view the parsed information in the form of maps, thus enabling a better understanding of yield interactions, pests, weeds, etc.
3. Remote Sensing
Remote sensing involves sensors that develop remote inferences about a particular object, land area, etc. In agriculture, it helps explore soil properties, identify crop type, and determine the crop yield.
