I am wondering if you know any well implemented geoportals for Participatory Spatial Planning. I am looking for the one related to environmental protection or connected somehow with the topic (but of course not only- if you have any just put it here).
A very sucessfull example is the one from Belo Horizonte's city council here in Brazil.
More details in: http://opdigital.pbh.gov.br/ (I guess it's portuguese only).
I'm currently working on a project to do this for another city council, but I can't give further details - for now :D
MarineMap is a spatial planning tool for the marine environment, used to engage stakeholders in the process of planning marine protected areas.
I found myself this project very interesting.
Another interesting projects i've found:
If i will find more i will put it here.
