pyturf
Read the docs
pyturf is a powerful geospatial library written in python, based on turf.js,
a popular library written in javascript. It follows the same modular structure and maintains the same functionality as the original
modules in that library for maximum compatibility.
It includes traditional geospatial operations, as well as helper functions for creating and manipulating GeoJSON data.
Installation
$ pip install pyturf
Usage
Most pyturf modules expect as input GeoJSON features or a collection of these, which can be the following:
- Point / MultiPoint
- LineString / MultiLineString
- Polygon / MultiPolygon
These can either be defined as a python dictionary or as objects from pyturf helper classes.
# example as a dictionary:
point1 = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Point",
# Note order: longitude, latitude.
"coordinates": [-73.988214, 40.749128]
}
}
...
# Example using objects from helper classes
from turf import point
# Note order: longitude, latitude.
point1 = point([-73.988214, 40.749128])In order to use the modules, one can import directly from pyturf, such as:
from turf import distance, point
point1 = point([-73.988214, 40.749128])
point2 = point([-73.838432, 40.738484])
dist = distance(point1, point2, {"units": "miles"})Available Modules
