More than 100 years ago National Geo-spatial Information (NGI), a component of the Department of Agriculture, Land Reform and Rural Development (DALRRD) commenced with the establishment of an integrated survey system and provision of extensive mapping and aerial imagery coverage of the country. NGI is also known as South Africa's national mapping organisation.
The integrated survey system expedites and facilitates orderly development while the mapping and associated products facilitate sustainable development. In more recent years, NGI established an active control survey network of continuously operating GNSS base stations covering South Africa, all managed and controlled by a single control centre situated in the offices of NGI.
NGI has the largest repository of historical aerial photography dating back to 1926 and continues to provide national digital aerial imagery coverage.
NGI establishes and maintains the national geodetic and control survey infrastructure.
NGI provides national mapping, digital topographic and other Geo-Spatial Information.
NGI is a key contributor to the South African Spatial Data Infrastructure.
NGI provides professional and advisory services.
