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.

line-string clj

(line-string points)

Make a LineString from a collection of points.

linear-ring clj

(linear-ring points)

Used for constructing Polygons from Points.

multi-line-string clj

(multi-line-string line-strings)

Make a MultiLineString from a collection of LineStrings.

multi-point clj

(multi-point points)

Make a MultiPoint from a collection of Points.

multi-polygon clj

(multi-polygon polygons)

Make 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)

Make a 2D or 3D Point.

polygon clj

(polygon linear-rings)

Make 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)

Return the geometry object with SRID set. Mutates the object.
