Läheisyyysanalyysit

Läheisyyysanalyysit, known in English as proximity analysis or closeness analysis, is a type of spatial analysis used in geographic information systems (GIS) and other data analysis fields. It focuses on understanding the spatial relationships and accessibility between different locations or features. The core idea is to quantify how close or accessible certain points are to each other or to a set of points.

This analysis can take various forms. One common approach involves calculating distances between features, such as the straight-line distance or network distance along roads. Another method is to define service areas or buffer zones around points of interest, indicating the region within a certain distance. Läheisyyysanalyysit can also involve measuring the number of features within a specified radius or identifying the nearest feature from a given location.

The applications of läheisyyysanalyysit are diverse. In urban planning, it can be used to determine the accessibility of public services, schools, or transportation hubs for residents. For businesses, it helps in site selection by identifying locations with high customer potential or proximity to suppliers. In emergency services, it can be used to calculate response times and optimize resource deployment. Environmental studies might use it to assess the impact of pollution sources on nearby populations or ecosystems. The results of these analyses help in decision-making processes that involve spatial considerations.
