Ordnance Survey

Definition

Ordnance Survey is the national mapping agency for Great Britain and is renowned as one of the largest and most prolific producers of maps worldwide. This institution is responsible for creating highly detailed geographic data and cartographic products, which serve a variety of purposes, from everyday navigation to advanced geographic information system (GIS) applications. By deploying advanced geodetic and surveying techniques, Ordnance Survey ensures that their map products are accurate, reliable, and up-to-date, thus serving as a critical resource for governmental, commercial, and public utilization.

What is Ordnance Survey?

Ordnance Survey encompasses the comprehensive process of gathering, analyzing, and presenting geospatial data to create maps that represent Great Britain's landscape accurately. This process involves various components, such as aerial photography, field surveys, and advanced geographic information systems, to produce maps that include a myriad of features like topography, infrastructure, land use, and administrative boundaries. The organization utilizes a network of geodetic controls, which are precise reference points used to ensure the spatial accuracy of the maps, integral for applications in navigation, land use planning, environmental management, and emergency response, among others. Through consistent updates and technological advancements, Ordnance Survey remains a pivotal entity in supporting the mapping needs of Great Britain and beyond.
