MapboxGL IPython渲染器
mapboxgl-notebook的Python项目详细描述
MapboxGlu笔记本
MabBOXGL为IPython笔记本电脑提供多层支持和灵活性。
如果您正在寻找多层mapboxgl ipython模块，那么这个存储库是一个合适的位置。
创建此项目时考虑到：
- 从一开始就提供多层支持。
- 少量的python、html和javascript代码。
- 支持MapboxGL表达式。 具有很高的灵活性，可以创建新的层。
安装： 下载代码，使用pip从github或pypi安装：
pip install mapboxgl_notebook
示例：
import os
from mapboxgl_notebook.map import MapboxMap
from mapboxgl_notebook.sources import GeoJSONSource
from mapboxgl_notebook.layers import PointCircleLayer, LineStringLineLayer, PolygonFillLayer
from mapboxgl_notebook.properties import Paint
from mapboxgl_notebook.interactions import ClickInteraction, HoverInteraction
access_token = os.environ.get('MAPBOX_ACCESS_TOKEN')
