What is Nearest Neighbour Analysis in Urban Geography
What is nearest neighbour analysis in urban geography Nearest neighbor analysis is a spatial analytical technique used in urban geography to examine the distribution pattern of points or features within a given area. It is primarily used to understand the level of clustering or dispersion of certain phenomena, such as urban amenities, population, or land use. The analysis involves measuring the distances between each point or feature in a dataset and its nearest neighboring point or feature. This distance information is then used to calculate a statistic that indicates the degree of clustering or dispersion. The most commonly used statistic in nearest neighbor analysis is the Nearest Neighbor Index (NNI), also known as the Average Nearest Neighbor (ANN) index. The NNI compares the observed distribution pattern with that of a random distribution. If the observed pattern is significantly different from random, it suggests a non-random spatial arrangement. The NNI is calculated by di...
