The Landscape Values and PPGIS Institute advocates the use of PPGIS to increase citizen engagement which encourages effective governance. Toward that end, the Institute seeks to work with progressive government agencies and NGOs to provide low cost, turn-key internet-based PPGIS systems for collecting and analyzing data. The Institute is a non-profit entity and only seeks to cover its costs of PPGIS set-up and administration. These costs are quite low and reasonable.
The Institute has provided PPGIS services for agencies such as the U.S. Forest Service (U.S.), NOAA (U.S.), Parks Victoria (Australia), NSW National Parks and Wildlife Service (Australia), and the Department of Conservation (New Zealand) to improve their land/marine planning processes. The Institute has also worked with The Nature Conservancy and National Wildlife Federation in the U.S.
Alternatively, you can use commercial mapping software available through a Finnish company called Mapita to develop your own PPGIS. The software is reasonably priced, reliable, and allows you to develop custom mapping surveys. You can learn about the mapping software product, called Maptionnaire, here.
