geo.gps module

geo.gps (Geo-Positioning)

Author:

Description:

This module is a submodule of geo and includes functions and classes for geographic issues (e.g. coordinate, area, tracks, …).

Contentlist:

class geo.gps.area(coord1, coord2)

Bases: object

Parameters:

Class to store a geographic area and support some calculations.

Example:

>>> import geo

>>> ar = geo.gps.area(...)
center_pos()

osm_map(map_code)
Parameters:

map_code – Map code as defined in geo.osm (e.g. geo.osm.MAP_STANDARD)

This Method returns a geo.osm.map instance.

Warning

Needs sphinx documentation!

class geo.gps.coordinate(**kwargs)

Bases: dict

Parameters:

  • lon (float) – Londitude

  • lat (float) – Latitude

  • height (float) – Height

  • time (int) – Time (Seconds since 1970)

Class to store a geographic coodinate and support some calculations.

Example:

>>> import geo

>>> ab = geo.gps.coordinate(lat=49.976596,lon=9.1481443)
>>> gb = geo.gps.coordinate(lat=53.6908298,lon=12.1583252)
>>> ab.dist_to(gb) / 1000
462.3182843470017
>>> ab.angle_to(gb) / math.pi * 180
39.02285256685333
HIGHT = 'hight'
LATITUDE = 'lat'
LONGITUDE = 'lon'
TIME = 'time'
angle_to(coord)

This Method calculates the geographic direction in radiant from this to the given coordinate.

Note

North is 0 (turning right). That means east is math.pi/2.

Parameters:

coord (corrdinate) – Target coordinate.

Returns:

The geographic direction in radiant.

Return type:

int or float

dist_to(coord)

This Method calcultes the distance from this coordinate to a given coordinate.

Parameters:

coord (coordinate) – Target coordinate.

Returns:

The distance between two coordinates in meters.

Return type:

int or float

Raises:
class geo.gps.track

Bases: list

Class to store a a tracks and support some calculations.

Example:

>>> import geo

>>> ...
append(coord)
