Grupo Kalinangan, Inc. (GKI) volunteers worked together to upload and update resources in the Philippine Heritage Map during the organization’s Annual Mapathon on 27 July 2019 at 933 MNL Creatives, Sampaloc, Manila.

The Philippine Heritage Map (PHM) is an online portal initiated and maintained by GKI, and made specifically to create an authoritative and comprehensive inventory of all heritage structures and historic events in the Philippines. It aims to help promote and protect the unique cultural heritage though a showcase of significant Philippine architecture, historic districts, towns and cities.

The GKI organizes the Annual Philippine Heritage Mapathon to continuously update PHM with cultural data gathered from different local government units and government agencies throughout the year.
