Hi StackOverflow Community,

I have year-over-year images that I have pulled from Google Earth Image, and I want to animate them so that it's easier to analyze.

I tried to use Folium, which has a plugin that enables the animation with a slider. (i.e. TimestampedGeo). This is the code:

import ee
import folium
import folium.plugins as fplugins


"""
Sources:
- .ipynb#scrollTo=3qB3W9rDfoma
- .html
"""

ee.Authenticate()

ee.Initialize()


dem = ee.Image('USGS/SRTMGL1_003')


m = folium.Map(
    location=(chosen_lat, chosen_lon),
    zoom_start=9,
    height=300
)


features = [
    {
        "type": "Feature",
        "geometry": dem.updateMask(dem.gt(0)).getMapId({}),
        "properties": {"times": ["2017-06-02T00:30:00", "2017-06-02T00:40:00"]}
    }
]

fplugins.TimestampedGeoJson(
    data={
        "type": "FeatureCollection",
        "features": features,
    },
    period="PT1M",
    add_last_point=True,
).add_to(m)

m

The above code keeps giving this error message:

TypeError                                 Traceback (most recent call last)

Does anyone know how to fix this, or whether it's possible for Folium to animate images? I'm also open to trying any Python libraries that can achieve the same.
