Developer Community



Mapping indigenous oral histories: The project to develop this application was initiated by the Amazon Conservation Team (ACT), an organization which partners with indigenous and other traditional communities in the Amazon rainforest to help them protect their ancestral lands and maintain their traditional culture. In 2017, ACT realized the need to develop a custom interactive mapping application designed for mapping and safeguarding the intangible cultural heritage expressed in indigenous place-based oral histories, which are at risk of disappearing. Through Mapbox's Community Team, we were acquainted with Ruby for Good, a volunteer developer community, who got started building Terrastories. The first version of the application was built at Ruby for Good 2018 for a Surinamese community called the Matawai. ACT is also using Terrastories to map oral histories with the Wauja in Brazil and the Kogui in Colombia.

Terrastories is a free and open-source (FOSS) application and we are looking forward to working with communities across the world in helping them use Terrastories, as recently undertaken in Ontario, Canada.

Currently, Terrastories is being maintained by Digital Democracy.


The Terrastories Stewards are a small, mostly volunteer collective who are guiding the development roadmap, managing and building the volunteer community, reviewing contributions to the code, and getting interested users started in working with Terrastories.
