Base map and model building
A base map that provides necessary background information of the target area, as well as the 3D model of the known geographic landscape, are the first requirement to start participatory 3D design. The 3D model can be generated by software like ContextCapture. Elements such as cartographic clarity, date, detail level, etc., should be decided in this step.
To empower the participants to freely explore the base 3D model, a training session is recommended. Participants should know how to read 3D maps and how to input their information.
Data/proposal collection and textual information transposing
According the project topics, participants may provide local information or create their preferred design/plan. No matter in which case, participants may provide textual information that they cannot transfer into visualisation by themselves, so organisers should transpose that data/information to the 3D model.
Documenting and publishing the models
3D models generated in the previous steps can also benefit future design and other aspects of planning such as energy, transportation, public services, etc. Publising the models as open data could encourage the public and other third-party organisations to contribute to the area in a sustainable and long-term way.
