 # Transport from farm to factory - using IoT to track food deliveries
 
-Many farmers grow food to sell - either they are commercial growers who sell everything they grow, or they are subsistence farmers who sell their excess produce to buy necessities. Somehow the food has to get from the farm to the consumer, and this usually relies on bulk transport from farms, to hubs or processing plants, then on to stores. For example, a tomato farmer will harvest tomatoes, pack them into boxes, load the boxes into a truck then deliver to a processing plant. The tomatoes will then be sorted, and from there delivered to the consumers in the form of retail, food processing, or restaurants.

-IoT can help with this supply chain by tracking the food in transit - ensuring drivers are going where they should, monitoring vehicle locations, and getting alerts when vehicles arrive so that food can be unloaded, ready for processing as soon as possible.

-> 🎓 A *supply chain* is the sequence of activities to make and deliver something. For example, in tomato farming it covers seed, soil, fertilizer and water supply, growing tomatoes, delivering tomatoes to a central hub, transporting them to a supermarkets local hub, transporting to the individual supermarket, being put out on display, then sold to a consumer and taken home to eat. Each step is like the links in a chain.

 ## Introduction
 
-The main process for getting food from a farmer to a consumer involves loading boxes of produce on to trucks, ships, airplanes, or other commercial transport vehicles, and delivering the food somewhere - either direct to a customer, or to a central hub or warehouse for processing. The whole end-to-end process from farm to consumer is part of a process called the *supply chain*. The video below from Arizona State University's W. P. Carey School of Business talks about the idea of the supply chain and how it is managed in more detail.

 Adding IoT devices can drastically improve your supply chain, allowing you to manage where items are, plan transport and goods handling better, and respond quicker to problems.
 
-When managing a fleet of vehicles such as trucks, it is helpful to know where each vehicle is at a given time. Vehicles can be fitted with GPS sensors that send their location to IoT systems, allowing the owners to pinpoint their location, see the route they have taken, and know when they will arrive at their destination. Most vehicles operate outside of WiFi coverage, so they use cellular networks to send this kind of data. Sometimes the GPS sensor is built into more complex IoT devices such as electronic log books. These devices track how long a truck has been driven for to ensure drivers are in compliance with local laws on working hours.

 ## Geospatial coordinates
 
-Geospatial coordinates are used to define points on the Earth's surface, similar to how coordinates can be used to draw to a pixel on a computer screen or position stitches in cross stitch. For a single point, you have a pair of coordinates. For example, the Microsoft Campus in Redmond, Washington, USA is located at 47.6423109,-122.1390293.

 ### Latitude and longitude
 
-The Earth is a sphere - a three-dimensional circle. Because of this, points are defined is by dividing it into 360 degrees, the same as the geometry of circles. Latitude measures the number of degrees north to south, longitude measures the number of degrees east to west.
