As super simple how to on how to map you global friends on a ..... Map.
let's get started:
We're using Google Forms to collect the data. For that, adjust the existing forms title/description/questions to your needs:
https://docs.google.com/forms/d/1EF9hyL7wD4pODqnWkXZ-tMu66o5Qi0hSzCNuZJS2_LA/edit
In order to collect the data, send an email/tweet/facebook message to your friends, asking to fill out this form:
https://docs.google.com/forms/d/1EF9hyL7wD4pODqnWkXZ-tMu66o5Qi0hSzCNuZJS2_LA/viewform
(same as clicking 'senden' or 'send' button in step 1.)
Once your friends answered the questions, see the results here in the connected google spreadsheet:
https://docs.google.com/spreadsheets/d/1JEocaZbvkChb8n7tQmYSTXQhzL40uWXcKRymZ_tvr88/edit
Finally, to show the location of your friends on a map, go to https://www.mapcustomizer.com and klick on 'Bulk Entry' on the right side. There, copy column D from the spreadsheet of step 3. Now, all your friends locations should appear on a map
For future reference, save the map by clicking 'save' next to 'Bulk Entry'. Name it what you want. E.g. I did a test with
https://www.mapcustomizer.com/map/test%20hallot
To embed the map into your website, you need to add an iframe and reference the saved map. See https://raw.githubusercontent.com/rngtng/global-friends/master/index.html for an source example. Apparently 'mapcustomizer' detects the iframe and redirects to the actual page asap a user action is triggered. Maybe other projects besides mapcustomizer offer a better solution here.
An example Website with an iframe including the mapcustomizer map is here: https://rngtng.github.io/global-friends/
