folium-vectorgrid

About The Project

Now part of folium plugins as of v0.13.0.

This library fills a hole in foliums plugin eco-system. Wrapping Leaflet.VectorGrid into a folium plugin, users can now add vector tile layers (e.g. Mapbox, OpenMapTiles) to their folium maps.

Built With

• folium
• Leaflet.VectorGrid

Getting Started

Prerequisite

Install Poetry.

Installation

as dependency

poetry add git+https://github.com/iwpnd/folium-vectorgrid.git

local development

1. Clone and install

   git clone https://github.com/iwpnd/folium-vectorgrid.git
   poetry install
   

2. Test it!

   poe test  # or poetry run pytest .
   

Usage

from folium_vectorgrid import VectorGridProtobuf
import folium

url = "https://free-{s}.tilehosting.com/data/v3/{z}/{x}/{y}.pbf?token={token}"

m = folium.Map()
options = {
    "subdomain": "my_subdomain",
    "token": "my_token",
    "vectorTileLayerStyles": {
        "my_layer":{
            "fill": True,
            "weight": 1,
            "fillColor": 'green',
            "color": 'black',
            "fillOpacity":0.6,
            "opacity":0.6
        },
    }
}

vc = VectorGridProtobuf(url, "folium_layer_name", options)
m.add_child(vc)
m

Or with conditional styling

import folium
from folium_vectorgrid import VectorGridProtobuf

m = folium.Map()
url = "https://free-{s}.tilehosting.com/data/v3/{z}/{x}/{y}.pbf?token={token}"

options = '''{
  "subdomain": "tilehosting",
  "token": "af6P2G9dztAt1F75x7KYt0Hx2DJR052G",
  "vectorTileLayerStyles": {
    "my_layer": function(f) {
      if (f.type === 'parks') {
        return {
          "fill": true,
          "weight": 1,
          "fillColor": 'green',
          "color": 'black',
          "fillOpacity":0.6,
          "opacity":0.6
        };
      }

      if (f.type === 'water') {
        return {
          "fill": true,
          "weight": 1,
          "fillColor": 'purple',
          "color": 'black',
          "fillOpacity":0.6,
          "opacity":0.6
        };
      }
    }
  }
