I have a code that running in every 2 seconds. This code prints the coordinate information every two seconds. I want to collect these coordinates in a list but I cannot. How can I do that ?

Code:

Using fetch API and async/await, is it possible to continue polling indefinitely, regardless of availability of a URL? I anticipate that a URL might become available eventually, so I want to keep trying until a condition is met. Tried to come up with a minimum viable code sample and I'm not sure I pulled it off:

I'm trying to do a chloropeth map following this guide: https://www.r-graph-gallery.com/327-chloropleth-map-from-geojson-with-ggplot2.html

I mixed a bit of the tutorial with this answer(Chloropleth map with geojson and ggplot2), since I wasn't getting the result I expected. The cities were being filled with the same color, and it seemed as R wasn't understanding the data as numeric, and filled every city that had at least 1 user with the default color. (tried using as.numeric, didnt work either)

I downloaded "users by city" data from my website from Google Analytics using

I want to create an offline map. I create map that baselayer is openstreetmap for small city (download all tiles and save in folders and it works).

I tried to use JavaScript to redirect visitors by country

The following call checks the IP of the country by visitor e.g. CN (China) and redirects it to an other web site.

I'm using vectorformats to display GeoDjango data on my map, following this resource. I have this in my views.py file :

I have terrain view in Cesium Sandcastle and I have loaded roads data in GeoJSON format, they are lines. I want to clamp them on terrain, like this example (in drop-down menu choose "Sample line positions and draw with depth test disabled") -> http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Ground%20Clamping.html&label=Tutorials In the example, the line you see is defined within code, but I have data (roads) on my PC which is loaded in app. When loaded, roads are flat (under the terrain) and somehow I have to clamp them on terrain but don't know how.

I have tried using the existing code from the example but haven't succeed.

This is my code for now:

I'm making a leaflet map that contains a geoJSON layer. When a point on the geoJSON layer is clicked, the YouTube video identified in that point (by a "youtube_id" field) opens in a leaflet control window. I would really like to be able to get the playback time of the video, and it seems like the only way to do this is with the YouTube iframe API, using their playback status functions.

The way I have the map working now is to add an iframe object to the leaflet control window, similar to how this tutorial works. This works to display the video, but there's no way to get the playback time as the video is playing. Here's the relevant part of my javascript:
