TimestampedWmsTileLayers

Add a time dimension to a WMS tile layer.

Note that we don’t render the output in this example, because the web service used here is not always available.

Exploring the WMS with OWSLib

from owslib.wms import WebMapService


url = "https://pae-paha.pacioos.hawaii.edu/thredds/wms/dhw_5km?service=WMS"

web_map_services = WebMapService(url)

print("\n".join(web_map_services.contents.keys()))

Layer metadata

layer = "CRW_SST"
wms = web_map_services.contents[layer]

name = wms.title

lon = (wms.boundingBox[0] + wms.boundingBox[2]) / 2.0
lat = (wms.boundingBox[1] + wms.boundingBox[3]) / 2.0
center = lat, lon

time_interval = "{0}/{1}".format(
    wms.timepositions[0].strip(), wms.timepositions[-1].strip()
)
style = "boxfill/sst_36"

if style not in wms.styles:
    style = None

Map with WmsTileLayer and TimestampedWmsTileLayers

m = folium.Map(location=[-40, -50], zoom_start=5)

wms_tile_layer = folium.WmsTileLayer(
    url=url,
    name=name,
    styles=style,
    fmt="image/png",
    transparent=True,
    layers=layer,
    overlay=True,
    COLORSCALERANGE="1.2,28",
).add_to(m)

folium.plugins.TimestampedWmsTileLayers(
    wms_tile_layer,
    period="PT1H",
    time_interval=time_interval,
).add_to(m)

folium.LayerControl().add_to(m)
