I am following some code examples to plot time aware coordinates on a folium map using the folium.plugins.TimestampedGeoJson method. As in the example, I'm using a for-loop to tie coordinates and timestamps in a list of GeoJson features. In other work I have formatted styling of GeoJson feature collections using lambda functions like so collection = folium.GeoJson( geoPandasDataframeObj, marker=folium.Circle(radius=8, fill_color=None, fill_opacity=1, color=None, weight=1), popup=folium.GeoJsonPopup(fields=["Field 1", "Field 2"]), style_function=lambda x: { "fillColor": colormap(x['properties']['Field 1']), "color": colormap(x['properties']['Field 2']), }, ) Is it possible to use a similar approach with TimestampedGeoJson to apply icon/marker styling using lambdas? The example code I'm using is here (Example Code): import folium from folium.plugins import TimestampedGeoJson m = folium.Map( location=[56.096555, -3.64746], tiles="cartodbpositron", zoom_start=5, ) table = """\ <table style=\'width:100%\'> <tr> <th>Firstname</th> <th>Lastname</th> <th>Age</th> </tr> <tr> <td>Jill</td> <td>Smith</td> <td>50</td> </tr> <tr> <td>Eve</td> <td>Jackson</td> <td>94</td> </tr> </table> """ points = [ { "time": "2017-06-02", "popup": "<h1>address1</h1>", "coordinates": [-2.548828, 51.467697], }, { "time": "2017-07-02", "popup": "<h2 style='color:blue;'>address2<h2>", "coordinates": [-0.087891, 51.536086], }, { "time": "2017-08-02", "popup": "<h2 style='colorrange;'>address3<h2>", "coordinates": [-6.240234, 53.383328], }, { "time": "2017-09-02", "popup": "<h2 style='color:green;'>address4<h2>", "coordinates": [-1.40625, 60.261617], }, { "time": "2017-10-02", "popup": table, "coordinates": [-1.516113, 53.800651] }, ] times = ["2017-06-02", "2017-07-02", "2017-08-02", "2017-09-02", "2017-10-02"] coords = [(-2.548828, 51.467697), (-0.087891, 51.536086), (-6.240234, 53.383328), (-1.40625, 60.261617), (-1.516113, 53.800651)] colors = ['#e41a1c','#377eb8','#4daf4a','#984ea3','#ff7f00'] features = [] for point in range(0,len(times)): features.append({ "type": "Feature", "geometry": { "type": "Point", "coordinates": coords[point], }, "properties": { "time": times[point], "icon": "circle", "iconstyle": {"color": colors[point], "fill": "true", "fillOpacity": 1.0, "radius": 5}, }, }) folium.plugins.TimestampedGeoJson( { "type": "FeatureCollection", "features": features, }, period="P7D", add_last_point=True, ).add_to(m) m.save('TimestampedGeoJsonPoint.html') Continue reading...
