locationare

Locationare is a term in geospatial information science and augmented reality describing a method to link data objects to precise geographic locations and defined spatial extents. A locationare record notes where an object exists and the area considered its influence, enabling spatial queries and context-aware display.

Etymology and scope: The word blends location and area and is used in research and industry discussions on location-based data models. It is not a standardized term across all geospatial communities and has multiple implementations.

Definition and data model: A locationare item typically includes coordinates (lat, lon, optionally altitude), an extent geometry (radius, polygon, or other shape), a coordinate reference system such as WGS84, and metadata like timestamp and accuracy. Data may be stored as GeoJSON, GML, or similar.

Applications: It supports augmented reality object placement, asset management, urban planning, and environmental monitoring where the extent of influence matters.

Standards and considerations: Locationare data often aligns with existing geospatial standards and interoperates with GIS platforms. Privacy, data quality, and precision are common concerns, especially in dense areas or rapidly updated datasets.

History: The concept appeared in GIS literature in the early 2010s and has since seen use in both academic and industry contexts, with varying levels of formal standardization.
