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.
Note: I wrote this as a tiny side project I built while developing an app that ingested geojson. The geojson library has a utility for generating random values, so if you're here looking for a way to generate random geojson data and you don't already use faker, you should prefer the geojson.utilities.generate_random
Install with pip:
pip install geofactory
GeoFactory is a Faker 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() # valid geojson Point feature - all methods follow this pattern
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
multipolygon
Returns a geojson multipolygon with a specific number of randomly arranged polygons :param: count_limit - determines how many polygons will be created
geometry_collection
Note: use of geometry collections is discouraged by the geojson spec.
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
Feel free to open an issue, fork the repo, submit a PR, etc.
If you make changes to existing methods, run pytest to make sure they all
are still passing and include coverage for your new methods/classes.
