Gnomonic refers to a type of projection used in cartography (the science of creating maps) where the surface of the Earth is projected onto a plane tangential to a single point on the Earth's surface. This projection is commonly known as the "gnomonic projection" and is used to create maps of small areas such as cities or regions.
In the gnomonic projection, great circles (the shortest distance between two points on a sphere) are shown as straight lines, and all other lines are curved. This makes the gnomonic projection useful for navigation and for determining the shortest distance between two points on the Earth's surface.
The gnomonic projection has some limitations, however. It distorts distances and areas outside of the central point, making it unsuitable for mapping larger regions or the entire globe. Additionally, it distorts the shapes of objects that are not near the center of the map.
