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 think it would be fairly straightforward to implement something like this using the Google maps API. There is an example of how to do this in PHP here.

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.
