I need more points!
Point Pattern Analysis
Point as a fixed entity
points are conceptually similar to polygons/lines
the goal is, taking a fixed location, to model other aspects of the data
Examples
Cities (in most cases)
Shops
Polygons represented as their centroid
Point as an event
Points can represent a fundamentally different way to approach spatial analysis
rather than exhausting the entire space,
points can be events subject to occur anywhere
The location of the event is part
of what we are trying to understand/model
The interest focuses on characterizing
the pattern that the points follow over space
Examples
Crime location
Trees
Meteorite hits
Instagram photo locations
Point patterns
Distribution of points over a portion of space
The assumption is a point can happen anywhere in that space but only happens in specific locations.
Unmarked
locations only
Marked
values attached to each point
Point Pattern Analysis
Describe, characterise, and explain point patterns,
focusing on their generating process
