Project description

A Python 3 module to convert matplotlib contour plots to geojson.

Designed to show geographical contour plots, created with matplotlib/pyplot, as vector layer on interactive maps interactive slippy maps like OpenLayers and Leaflet.

Installation

The recommended way to install is via pip,

Usage

contour plot to geojson

import numpy
import matplotlib.pyplot as plt
import geojsoncontour

# Create contour data lon_range, lat_range, Z
<your code here>

# Create a contour plot plot from grid (lat, lon) data
figure = plt.figure()
ax = figure.add_subplot(111)
contour = ax.contour(lon_range, lat_range, Z, levels=levels, cmap=plt.cm.jet)

# Convert matplotlib contour to geojson
geojsoncontour.contour_to_geojson(
    contour=contour,
    geojson_filepath='out.geojson',
    contour_labels=levels,
    ndigits=3,
    unit='m'
)

See example1.py for a basic but complete example.

Show the geojson on a map

An easy way to show the generated geojson on a map is the online geojson renderer geojson.io.
