Proximity Analysis
The process of analysing spatial relationships based on distance, such as identifying features within a certain radius of a point (inferred from standard GIS usage).
How is a Proximity Analysis defined?
In GIS, proximity analysis is a geographical analytic method that is used to calculate the separation between features and, using that distance, examine the links and effects of one feature on another.
The process of analysing the proximity of spatial features (like points, lines, or polygons) to one another is known as proximity analysis. It provides answers to queries such as:
What lies inside a specific radius of a place?
Which characteristics are closest to a specific location?
How far is the closest hospital from each school?
By showing how locations affect or are influenced by surrounding elements, proximity analysis facilitates better decision-making by illuminating spatial linkages based on distance.

A spatial method for figuring out the proximity or separation of geographic features is GIS proximity analysis. By calculating the distances between items, it facilitates the identification of connections, trends, or accessibility. Common uses include determining the closest facilities, evaluating the effects on the environment, designing routes, and examining service regions. Urban planning, emergency response, transit logistics, and resource management all depend on this study.
One GIS technique for determining the separation or proximity of geographic features is spatial proximity analysis. When determining the closest facilities, evaluating accessibility, or examining event clustering, it assists in identifying connections, patterns, or interactions between items. In order to facilitate well-informed decision-making, this analysis is frequently utilized in environmental research, urban planning, and logistics.
Planning, environmental management, and decision-making are aided by buffer analysis, which in GIS constructs zones around points, lines, or polygons to demonstrate closeness and influence.
In GIS, distance analysis is a spatial method for calculating and assessing the separation between geographic elements, such polygons, lines, and points. By computing straight-line (Euclidean) distance, network distance along roadways, or cost distance taking into account terrain and barriers, it assists in identifying closeness, accessibility, and geographical linkages. Site selection, transportation, urban planning, and environmental studies all make extensive use of this technique.
