geom - Geometry Helper Functions

This module provides various helper functions for geometry handling. Note: remember to apply a location handler before in order to use these geometry utilities on node locations.

Geometry Factories

class osmium.geom.WKBFactory

Factory that creates WKB from osmium geometries.

create_linestring(self: osmium.geom.WKBFactory, list: object, use_nodes: osmium.geom.use_nodes = <use_nodes.UNIQUE: 1>, direction: osmium.geom.direction = <direction.FORWARD: 0>) → str

Create a LineString geometry from a osmium.osm.Way.

create_multipolygon(self: osmium.geom.WKBFactory, area: object) → str

Create a MultiPolygon geometry from a osmium.osm.Area.

create_point(self: osmium.geom.WKBFactory, pt: object) → str

Create a point geometry from a osmium.osm.Node.

property epsg

(read-only) EPSG number of the output geometry.

property proj_string

(read-only) projection string of the output geometry.

class osmium.geom.WKTFactory

Factory that creates WKT from osmium geometries.

create_linestring(self: osmium.geom.WKTFactory, list: object, use_nodes: osmium.geom.use_nodes = <use_nodes.UNIQUE: 1>, direction: osmium.geom.direction = <direction.FORWARD: 0>) → str

Create a LineString geometry from a osmium.osm.Way.

create_multipolygon(self: osmium.geom.WKTFactory, area: object) → str

Create a MultiPolygon geometry from a osmium.osm.Area.

create_point(self: osmium.geom.WKTFactory, pt: object) → str

Create a point geometry from a osmium.osm.Node.

property epsg

(read-only) EPSG number of the output geometry.

property proj_string

(read-only) projection string of the output geometry.

class osmium.geom.GeoJSONFactory

Factory that creates GeoJSON geometries from osmium geometries.

create_linestring(self: osmium.geom.GeoJSONFactory, list: object, use_nodes: osmium.geom.use_nodes = <use_nodes.UNIQUE: 1>, direction: osmium.geom.direction = <direction.FORWARD: 0>) → str

Create a LineString geometry from a osmium.osm.Way.

create_multipolygon(self: osmium.geom.GeoJSONFactory, area: object) → str

Create a MultiPolygon geometry from a osmium.osm.Area.

create_point(self: osmium.geom.GeoJSONFactory, pt: object) → str

Create a point geometry from a osmium.osm.Node.

property epsg

(read-only) EPSG number of the output geometry.

property proj_string

(read-only) projection string of the output geometry.

Other Functions

osmium.geom.haversine_distance(list: object) → float

Compute the distance using the Haversine algorithm which takes the curvature of earth into account. If a WayNodeList is given as a parameter the total length of the way in meters is computed.
