Polygon/Multipolygon#
Example Polygon#
You can easily create a Polygon providing the list of vertex locations (in lat/lng).
from ipyleaflet import Map, Polygon
polygon = Polygon(
locations=[(42, -49), (43, -49), (43, -48)],
color="green",
fill_color="green"
)
m = Map(center=(42.5531, -48.6914), zoom=6)
m.add(polygon);
m
Because the Polygon an interactive widget, you can dynamically update the locations/color from Python, and you will see updated on the Map.
Example Polygon with holes#
You can define holes in your Polygon by using nested lists of vertex locations.
from ipyleaflet import Map, Polygon
polygon = Polygon(
locations= [
[(37, -109.05), (41, -109.03), (41, -102.05), (37, -102.04)],
[(37.29, -108.58), (40.71, -108.58), (40.71, -102.50), (37.29, -102.50)]
],
color="green",
fill_color="green"
)
m = Map(center=(37.5531, -109.6914), zoom=5)
m.add(polygon);
m
Example MultiPolygon#
from ipyleaflet import Map, Polygon
multipolygon = Polygon(
locations=[
[(42, -49), (43, -49), (43, -48)],
[(44,-49), (43, -50), (44,-50)]
],
color="green",
fill_color="green"
)
m = Map(center=(42.5531, -48.6914), zoom=6)
m.add(multipolygon);
m
Example Editable Polygon#
If transform is set to True, you can dynamically edit the polygon with the mouse.
from ipyleaflet import Map, Polygon
polygon = Polygon(
locations=[(42, -49), (43, -49), (43, -48)],
color="green",
fill_color="green",
transform=True
)
m = Map(center=(42.5531, -48.6914), zoom=6)
m.add(polygon);
m
