Neighbourhood Analysis
A spatial analysis technique that examines the characteristics or relationships of a cell or feature in relation to its surrounding cells or features, often used in raster analysis (inferred from standard GIS usage).
What is Neighbourhood Analysis?
Neighbourhood analysis is a GIS spatial analysis technique that looks at how a location and its surroundings relate to one another within a certain area, or "neighbourhood." It entails assessing the impact of neighboring cells' or features' properties on the value or state of a centre cell or point.
This technique is frequently used in raster data analysis, where statistical parameters, such as mean, maximum, or standard deviation, are determined based on the nearby cells in a moving window (such as 3x3 or 5x5 pixels). It can be used, for instance, to smooth data, find trends, locate hotspots, and evaluate the slope and aspect of the landscape.
In order to extract insights from local spatial settings, neighbourhood analysis is crucial for environmental modelling, resource allocation, land use planning, and image processing.

The process of gathering, evaluating, and displaying spatial data to depict the social and physical characteristics of a community or region is known as neighbourhood mapping. Better planning, decision-making, and community development are made possible by its assistance in identifying resources, infrastructure, demography, and significant landmarks.
In order to find patterns, clusters, and linkages that are helpful for planning and study, spatial neighbourhood analysis examines how a site is impacted by the areas around it.
In order to comprehend how people live, interact, and use space, an urban neighbourhood study looks into the physical, sociological, and economic aspects of a city's surrounding area. It assists planners, academics, and politicians in enhancing urban living conditions and advancing sustainable development by concentrating on topics such as housing patterns, infrastructure, community amenities, demography, land use, and social dynamics.
In GIS, neighbourhood analysis looks at the geographical connections and trends around a certain feature or site. In order to help planners and researchers make well-informed decisions on urban growth, resource allocation, and environmental management, it assists in identifying influences from surrounding aspects, such as population density, land use, infrastructure, or environmental factors.
