    Replying to [ticket:260 knarf]:

    It would be nice to produce an (autmatically generated) map of the locations of ET users

    I recall having used a program (of yours?) that accepted latitude and longitude of various cities, then superimposed markers onto an image file of a world map at corresponding coordinates.

    I could write a script that queries geolocation databases by IP, then plugs the returned coordinates into your map-making program to generate it dynamically. Were we to keep records of this data, we could even visualize the growth of the ETK user base.

    I do have a similar script, for the OpenLayers API (which can use google, but also openstreetmap). I should clean my mess up - but it still means that we need to have the coordinate data.

    Daniel George, a grad student at NCSA produced such a map using Mathematica and the google maps API. He says

    I just wanted to add that an interactive Google map can be made by running the attached code to export a CSV file, which can then be simply imported using the map maker here: https://www.google.com/maps/d/u/0/

    The current map can be found at this link: https://wolfr.am/h9pXJpE0. It should be possible to embed this in the ET website. Each location is tagged with the name of the place as well.

    My wife recommends "folium":
    <https://anaconda.org/conda-forge/folium.> This is a Python package
    talking to the "folium" Javascript library that displays the map.

    Here is a simple example:

    The BHPToolkit map is made using the Google Maps - MyMaps service (www.google.com/mymaps <http://www.google.com/mymaps).> As we currently have a small number of users I have just been keeping the map up to date by hand. Unfortunately it does not look like there is a programatic way to use MyMaps (https://stackoverflow.com/questions/40488333/google-my-maps-api <https://stackoverflow.com/questions/40488333/google-my-maps-api).>
