Point

The simplest form of GeoJSON that SurrealDB supports is a geolocation point. These can be written using two different formats. The first format is a simple 2-element tuple (longitude, latitude).

UPDATE city:london SET centre = (-0.118092, 51.509865);

In addition, SurrealDB supports entering GeoJSON points using the traditional format.

No other properties must be present in the Point object.

UPDATE city:london SET centre = {
    type: "Point",
    coordinates: [-0.118092, 51.509865],
};

Line

A GeoJSON LineString value for storing a geometric path.

No other properties must be present in the LineString object.

CREATE journey SET route = {
	type: "LineString",
	coordinates: [
		[10.0, 11.2], [10.5, 11.9]
	]
};

Polygon

A GeoJSON Polygon value for storing a geometric area.

No other properties must be present in the Polygon object.

UPDATE city:london SET boundary = {
	type: "Polygon",
	coordinates: [[
		[-0.38314819, 51.37692386], [0.1785278, 51.37692386],
		[0.1785278, 51.61460570], [-0.38314819, 51.61460570],
		[-0.38314819, 51.37692386]
	]]
};

MultiPoint

MultiPoints can be used to store multiple geometry points in a single value.

No other properties must be present in the MultiPoint object.

UPDATE person:tobie SET locations = {
	type: "MultiPoint",
	coordinates: [
		[10.0, 11.2],
		[10.5, 11.9]
	],
};

MultiLine

MultiLines can be used to store multiple geometry lines in a single value.

No other properties must be present in the MultiLine object.

UPDATE travel:yellowstone SET routes = {
	type: "MultiLineString",
	coordinates: [
		[ [10.0, 11.2], [10.5, 11.9] ],
		[ [11.0, 12.2], [11.5, 12.9], [12.0, 13.0] ]
	]
};

MultiPolygon

MultiPolygons can be used to store multiple geometry polygons in a single value.

No other properties must be present in the MultiPolygon object.

UPDATE university:oxford SET locations = {
	type: "MultiPolygon",
	coordinates: [
		[
			[ [10.0, 11.2], [10.5, 11.9], [10.8, 12.0], [10.0, 11.2] ]
		],
		[
			[ [9.0, 11.2], [10.5, 11.9], [10.3, 13.0], [9.0, 11.2] ]
		]
	]
};

Collection

Collections can be used to store multiple different geometry types in a single value.

No other properties must be present in the Collection object.

UPDATE university:oxford SET buildings = {
	type: "GeometryCollection",
	geometries: [
		{
			type: "MultiPoint",
			coordinates: [
				[10.0, 11.2],
				[10.5, 11.9]
			],
		},
		{
			type: "Polygon",
			coordinates: [[
				[-0.38314819, 51.37692386], [0.1785278, 51.37692386],
				[0.1785278, 51.61460570], [-0.38314819, 51.61460570],
				[-0.38314819, 51.37692386]
			]]
		},
		{
			type: "MultiPolygon",
			coordinates: [
				[
					[ [10.0, 11.2], [10.5, 11.9], [10.8, 12.0], [10.0, 11.2] ]
				],
				[
					[ [9.0, 11.2], [10.5, 11.9], [10.3, 13.0], [9.0, 11.2] ]
				]
			]
		}
	]
};
