I want to draw Timestamped GeoJSON using plugins.TimestampedGeoJson.
But my time bar in folium map shows "Time not available" and doesn't work.
I cannot find which part of my variables are wrong.
Variables I used are as follows.
How can I make my time bar work?

I tried to draw folium map.
But my time lower left in map left doesn't work.
m = folium.Map([37.5650172,126.8494648], zoom_start = 10)
plugins.TimestampedGeoJson( { 'type': 'FeatureCollection', 'features': features },
period='P1D',
add_last_point=True,
auto_play=False,
loop=False,
max_speed=1,
loop_button=True,
date_options='YYYY-MM-DD',
time_slider_drag_update=True,
duration='P1D' ).add_to(m)
m
I had the same problem, which was solved by the following in my case:
The issue you described occurs likely because your sub-dict-keyword "time" doesn't contain a list of equal length to the employed "coordinates" in each "feature".
Also, I suggest you to rename "time" to "times", as you will see in the original post on GitHub mentioned below.
Hereafter, I made a minimal example based on your provided feature list:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# * Example of correct feature list with length 1 * #
## Coordinates
coordinate_list1 = [[37.4725028, 126.4313798],
[37.478525899999994, 126.6663152],
[37.561648999999996, 126.79433700000001]]
## Times
# NOTE: if the same timestamp applies to all coordinates, create list with repeating timestamp of same length as coordinate list
times_list1 = ['2020-01-19'] * len(coordinate_list1)
## Features
# NOTE: fill in the coordinates and times, and name the associated time-keyword "times"
features = [{
'geometry': {
'coordinates': coordinate_list1,
'type': 'Point'
},
'properties': {
'icon': 'marker',
'iconstyle': {
'iconSize': [20, 20],
'iconUrl':
'http://downloadicons.net/sites/default/files/small-house-with-a-chimney-icon-70053.png'
},
'id': 'house',
'popup': 1,
'times': times_list1
},
'type': 'Feature'
}]
Fix this and it should work just fine.
The solution was cited from this discussion:
[...] the plugin requires each
featureto have a property"times", which should be a list containing either unix epoch timestamps in ms or ISO format timestamps. See https://python-visualization.github.io/folium/plugins.html#folium.plugins.TimestampedGeoJson
