Open mapWhy Open Field?
Make mapping, transparency, and participation more accessible.
Many mapping and engagement tools are expensive, difficult to access, or built primarily for technical specialists. Open Field was created as a free and approachable alternative.
Spatial information should be easier to understand, and the tools used to gather public input should be available to more people. Better access to information can support better conversations, stronger participation, and more transparent decisions.
About Open Field
Open Field is free to use and available to anyone. It is an independent project created by Justin Paul Ware and Spatial Politics to support more accessible mapping, stronger public engagement, and more transparent approaches to planning and civic decision-making.
Make your map public.
Build an interactive map, share spatial information, and create new ways for communities to participate. Open Field is free to use.
