regionslocated

Regionslocated is a concept in geographic information systems (GIS) used to describe the identification and record of geographic regions that are located within or intersected by a defined spatial extent. The term can refer to either the process of determining which predefined regions lie inside a polygon, bounding box, or area of interest, or to the resulting data field that lists those regions. In practice, regionslocated is produced by performing a spatial overlay or spatial join between a region layer (for example administrative or ecological regions) and the query geometry. The result is a set or list of region identifiers that correspond to the regions whose boundaries overlap the area.

Common methods include point-in-polygon tests for coarse queries, and polygon intersection or containment checks for more precise results. GIS tools and libraries such as QGIS, PostGIS, or ArcGIS provide functions to compute regionslocated automatically.

Applications include determining regional coverage for service delivery, demographic analysis by region, emergency management, and mapping user interfaces to show which regions are affected by a given incident or plan. Challenges include data quality and consistency across boundary definitions, temporal changes to regional borders, and projection-induced distortions that can affect overlap results. Good practice involves using authoritative boundary datasets, validating results against official records, and documenting the date of the boundary data used.
