Constructors for PostGIS geometry objects.

(require '[psql.spatial :as st])

geography clj

(geography geometry)

Tag a geometry with SRID 4326 (WGS84) so it can be stored in a PostGIS geography column, which requires a known SRID.

geometry-collection clj

(geometry-collection geometries)

Create a GeometryCollection from a collection of geometry objects.

line-string clj

(line-string points)

Create a LineString from a collection of points.

linear-ring clj

(linear-ring points)

Use to construct Polygons from Points.

multi-line-string clj

(multi-line-string line-strings)

Create a MultiLineString from a collection of LineStrings.

multi-point clj

(multi-point points)

Create a MultiPoint from a collection of Points.

multi-polygon clj

(multi-polygon polygons)

Create a MultiPolygon from a collection of Polygons.

pg-geom clj

(pg-geom geometry)

Wrap a geometry in the lightweight PGgeometry envelope for JDBC.

point clj

(point coll-or-str)

(point x y)

(point x y z)

Create a 2D or 3D Point.

polygon clj

(polygon linear-rings)

Create a Polygon from a collection of LinearRings.

srid clj

(srid geometry)

Return the SRID of a geometry object.

with-srid! clj

(with-srid! geometry srid)

Set the SRID on a geometry object. Mutate the object.
