just a quick comment, the google map feature will be back soon. if you check each site, you will find links to all sites till 2015. you will also find that the coordinates are embedded in the page. so as far as i can tell, the google map display will happen at least on a site level, maybe on a country level.
a few things i noticed though:
* 2016 data is missing.
+ previous discussion, but raising it again. some locations are only listed in the text, not in the web site, e.g. great canal, falun.
