T.E.R:R.A.I.N. is a system that allows community groups to digitize their resources and store spatial data in an online repository. It was created to help community groups: 1) map local data that is unique to the community and not available elsewhere, and 2) enter data online and link to other applications. A pilot project involved developing features for an open-source digital repository software used to map plants in Pukekura Park with data entered by students and the public. The system is designed to be free, open source software that is customizable, easy to install and use, with support from a large developer community.
