ISO 19111: Geographic information — Spatial referencing by coordinates

ISO 19111 is a critical standard for the spatial referencing of geographic information, ensuring that geospatial data is represented using consistent and accurate coordinate systems and coordinate reference systems (CRS). This standard enables the precise location of points on the Earth's surface to be documented and shared, facilitating interoperability between different geographic systems. It provides guidelines for handling coordinate systems, transformations, and spatial referencing, ensuring that geospatial data is correctly interpreted and used across a range of applications, from GIS and remote sensing to navigation and land planning.
