How Neighborly is K-Nearest Neighbors to GIS Pros?

Towards AI

Now, in the realm of geographic information systems (GIS), professionals often experience a complex interplay of emotions akin to the love-hate relationship one might have with neighbors. Enter K Nearest Neighbor (k-NN), a technique that personifies the very essence of propinquity and Neighborly dynamics.
