Render geojson using headless Chromium and leaflet.
pip install leaflet_render
from leaflet_render import render_geojson
geojson_string = """
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [-104.99404, 39.75621]
}
}
"""
rendered_bytes = render_geojson(geojson_string, width=600, height=600)
with open('render.png', 'wb') as f:
f.write(rendered_bytes)
The render_geojson functions returns the bytes of a PNG image. Note to pass a string and not dict as input.
Set the CHROMIUM_PATH environment variable or pass chromium_path as keyword argument.
A new instance of Chromium is spawned on each function call. Optimizations to batch render efficiently can be investigated in future.
A useful tool to translate between various GIS formats is GPS Babel.
To update leaflet sources, edit sources.txt then:
cd leaflet_render
wget -i ../sources.txt
