VRF (Vector Relational Format)
A relational model-based vector data format similar to VPF, used for storing and distributing geographic vector data.

Explain VRF (Vector Relational Format)?
The National Geospatial-Intelligence Agency (NGA) of the United States created the specialized digital geospatial data format known as VRF (Vector Relational Format). It is a Vector Product Format (VPF) implementation designed to interact with the National Geospatial Data Framework (NGDF) and other mapping systems used in defence.
Geographic features (such as roads, rivers, and borders) are arranged into feature classes and tables in VRF, which uses a relational database structure to store vector data. The format is appropriate for sophisticated spatial analysis, navigation systems, and military decision-making tools since it contains comprehensive geometry, attribute, and topology data.

In GIS, the Vector Relational Format is used to store geographic data like points, lines, and polygons connected to attribute-rich databases. This makes it possible to query, analyse, and map discrete features like boundaries, rivers, and roads in an effective manner.
Spatial characteristics and associated attribute information are stored in a structured, vector-based system using the Vector Relational Format (VRF) GIS data format. It allows for the smooth mapping, analysis, and querying of spatial data by effectively connecting geographic objects such as points, lines, and polygons with relational database tables. Large-scale mapping and urban planning projects frequently employ this format.
A GIS data structure called Vector Relational Format (VRF) allows for the rapid searching, editing, and analysis of linked geographic data by storing spatial features—points, lines, and polygons—along with their characteristics in a relational database.
A GIS data model called VRF (Vector Relational Format) organizes and stores vector features, such as points, lines, and polygons, together with their characteristics. For mapping, network analysis, and terrain modelling, it makes effective querying, editing, and spatial analysis possible.
