Tobler's first 'law' of geography: All things are related but nearer things are more related than distant things. This is the concept that describes regularity

Tobler's first 'law' of geography: All things are related but nearer things are more related than distant things. This is the concept that describes regularity and order to all spatially variable phenomenon. It is essentially the concept of spatial autocorrelation. Without it, the world would be a chaotic place. Imagine if moving from one room to another meant you could encounter a 100-degree drop in temperature or if you had to regularly face a 100 m drop in elevation when walking 100 m down a road. It also means that we can infer an underlying spatial distribution from a sub-sample of point measurements, which is central to understanding most geographical phenomena.
