What is a GeoJSON Point?
A Point is the simplest GeoJSON geometry: one position written as [longitude, latitude] (optionally followed by an altitude in metres). Wrapped in a Feature, it can carry any properties you like, such as a name.
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [-74.0445, 40.6892]
},
"properties": { "name": "Statue of Liberty" }
}
Longitude first
GeoJSON (RFC 7946) always puts longitude before latitude — the opposite of the "lat, lng" order you see in Google Maps. Mixing them up is the most common GeoJSON mistake: a point meant for New York ends up in Antarctica. This generator always writes the correct order, and the Copy lat, lng button gives you the Google-Maps order when you need it.
Several points
Several points are usually stored as a FeatureCollection of Point features (each with its own properties). A MultiPoint geometry also exists, but it shares one set of properties for all positions, so it's less common in practice.
