A simple geojson provider for faker

Project description

GeoFactory

This is a faker provider that generates fake geojson data. It simulates all the different types of features and geometries in the geojson specification. There is also a test suite for the class and it's methods run with pytest.

Setup

Install from source:

pip install git+https://github.com/scook12/geofactory.git@master

OR

pipenv install git+https://github.com/scook12/geofactory.git@master#egg=geofactory

Install with pip:

pip install geofactory

Use

GeoFactory is just an additional community provider for geojson.

An example might look like this:

from faker import Faker

from geofactory import GeoFactory

factory = Faker()

factory.add_provider(GeoFactory)

pt = factory.point()

pt is now a valid geojson Point feature. All methods follow this pattern.

Methods

lnglat

Returns a given number of random longitude/latitude pairs.

point

Returns a single geojson point object with random coordinates

multipoint

Returns a multipoint geojson object with a random number of random points :param: count_limit - determines the maxiumum number of points generated

linestring

Returns a linestring geojson object with a random number of nodes :param: node_limit - determines the maxiumum number of nodes generated

multilinestring

Returns a multilinestring with a random number of segments with a random number of nodes :param: node_limit - determines maximum number of nodes for a given linestring :param: count_limit - determines the maximum number of line segments generated

polygon

Returns a randomly arranged polygon with a specific number of nodes :param: node_limit - determines how many nodes will be in the return polygon

multypolygon

Returns a geojson multipolygon with a specific number of randomly arranged polygons :param: count_limit - determines how many polygons will be created

geometry_collection

Returns a specific number of random geojson geometries as a collection :param: count_limit - determines how many geometries will be generated

feature

Returns a random geojson feature object

feature_collection

Returns a specific number of random features in a feature collection object :param: count_limit - determines how many features will be generated

to_file

Writes geojson object to file :param: path - full path and filename for data to be written to :param: data - valid geojson object to dump in path

Contribute

Open an issue, fork the repo, submit a PR. This is a tiny side project I built to be used while developing an app that ingested geojson, so there aren't a ton of guidelines.

If you make changes to existing methods, be sure to run pytest to make sure they all are still passing. If you write a new method or class, please include some basic pytest cases.
