The Association of Geographic Information System Group (G-SIG) 

is a youth-led non-profit organization in Timor-Leste dedicated to advancing the well-being of both people and the environment through sustainable advocacy, research, and the publication of activities related to OpenStreetMap, geoscience benefits, and other community-based initiatives. G-SIG focuses on the development of Geographic Information Systems (GIS) and actively engages in promoting the utilization of GIS technologies for the benefit of the community.

The association was established by geoscience and geographic information systems academic experts with the aim of enhancing and disseminating information to the general public, young academics, NGOs, and government agencies regarding geoscience activities, such as environmental risks, climate change, natural disasters, and natural resources. We are actively promoting the utilization of geospatial data through the application of geographic information systems in Timor-Leste. This is achieved through research endeavors, presentations, dissemination efforts, and training programs.

To ensure legal recognition, G-SIG Timor-Leste has completed the registration process with the Ministry of Justice, with Notary Management, and has been issued registration number N^o 06/DNRN-DGSRN/MJ/II/2023.
