I've recently taken IT team lead position in another global crowdsourced project "Let's do it World" (www.letsdoitworld.org) which is after cleaning up all the rubbish in the world. And we do steps to be sure that it will not be dirty again also. Believe it or not, but there are countries where some 15% of total population has participated in the one-day trash clean up event earlier this year; and there are actions in some 80 or so countries in the world. My specific task is to develop good World Waste Map, using web and smartphone tools. We have some tools, but they are not userfriendly, useful, social and fun enough yet. If any of your geowankers want to help us with it, just let me know. I have also specific question about geohex. Do you know anyone who has population-normalized geohex (or something similar) in at least national level, better if global. I mean grid where each cell has more or less equal number of people living in it? Obviously cells themselves have very different sizes. US census blocks are something like that? Or can you suggest a method to create this kind of grid? Jaak
