Coordinate
A numeric pair (x, y) that describes a position, often (longitude, latitude) in EPSG:4326 workflows.
Category: CRS & Coordinates · Also known as: x/y, lng/lat, lon/lat
Definition (expanded)
Coordinates are the building blocks of rings and polygons. In most web and GeoJSON contexts, x is longitude and y is latitude. If a polygon shows up in the wrong place, coordinate order and CRS are the first things to check.
