Mental mapping is used by an Indonesian non-governmental organisation called Kota Kita in undertaking participatory planning exercises with local communities.
Here is an example of the use of a form of mental mapping in a participatory design tool called a ‘transect walk’ where maps marking key spots in the community are created as Kota Kita staff take walks with community members: https://www.youtube.com/watch?v=xv7zSqHhTqs
For an explanation of the Transect Walk see Kota Kita’s ‘Social Design Field Guide’ (2014), a handbook of experiences in participatory design in Indonesia: http://www.kotakita.org/library
Mapping exercises were also used by Kota Kita in a study on cycling by women in the Indonesian city of Solo, to understand how women factory workers and school girls used the city in terms of the routes they travelled and the places where they experienced danger and obstacles: http://www.kotakita.org/publications-docs/WOW_Program%20Design_251015.pdf
