# geojsoncontour
[](https://travis-ci.org/bartromgens/geojsoncontour) [](https://badge.fury.io/py/geojsoncontour) [](https://coveralls.io/github/bartromgens/geojsoncontour?branch=master)
A Python 3 module to convert matplotlib contour plots to geojson. Supports both contour and contourf plots.
Designed to show geographical [contour plots](http://matplotlib.org/examples/pylab_examples/contour_demo.html),
created with [matplotlib/pyplot](https://github.com/matplotlib/matplotlib), as vector layer on interactive slippy maps like [OpenLayers](https://github.com/openlayers/ol3) and [Leaflet](https://github.com/Leaflet/Leaflet).
Demo project that uses geojsoncontour: [climatemaps.romgens.com](http://climatemaps.romgens.com)
## Installation
Install with pip,
```
pip install geojsoncontour
```
## Usage
Use `contour_to_geojson` to create a geojson with contour lines from a `matplotlib.contour` plot (not filled).
Use `contourf_to_geojson` to create a geojson with filled contours from a `matplotlib.contourf` plot.
### Contour plot to geojson
```python
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, cmap=plt.cm.jet)
# Convert matplotlib contour to geojson
geojson = geojsoncontour.contour_to_geojson(
contour=contour,
ndigits=3,
unit='m'
)
```
For filled contour plots (`matplotlib.contourf`) use `contourf_to_geojson`.
See [example_contour.py](examples/example_contour.py) and [example_contourf.py](examples/example_contourf.py) for simple but complete examples.
### Show the geojson on a map
An easy way to show the generated geojson on a map is the online geojson renderer [geojson.io](http://geojson.io) or [geojson.tools](http://geojson.tools).
### Style properties
Stroke color and width are set as geojson properties following https://github.com/mapbox/simplestyle-spec.
### Create geojson tiles
Try [geojson-vt](https://github.com/mapbox/geojson-vt) or [tippecanoe](https://github.com/mapbox/tippecanoe) if performance is an issue and you need to tile your geojson contours.
## Development
### Tests
Run all tests,
```
python -m unittest discover
```
### Release
Install setuptools, wheel and twine:
```
python -m pip install --upgrade setuptools wheel twine
```
Increase the version number in `setup.py`.
Create dist:
```
python setup.py sdist bdist_wheel
```
Upload:
```
twine upload dist/*
```
