Last Saturday, we gathered together OSM enthusiasts and humanitarian volunteers for Open Data Day with MapaTime! in SLU Baguio event - the first mapathon event hosted by Saint Louis University, and their very first Open Data Day Celebration. We are pleasantly surprised with the turnout of 30 plus participants, apart from SLU’s own students, we have guests from the University of Baguio next door, and 3 participants from Divine Word College of Vigan, and traveled 130 kilomters for 7-hours just to MapaTime! We even have representatives from a local NGO involved in disaster preparedness and response.

We started the program with a short background on Open Data, and the value it brings to the community, local governments, NGOs, researchers, and for humanitarian action, especially disaster preparedness. Thereafter, introduced the community’s OSMaPaaralan public school validation project and how said efforts can improve the quality of open data and OpenStreetMap, plus the practical value of mapping them accurately.

We set the minimum goal of mapping all available schools tasks in Baguio City, which the volunteers successfully completed within the activity, plus more:

During the workshop, I was pleased to make the acquaintance of several active contributors in the region, whom I found through the Active OSM Contributors layer of


All-in-all, together with another Open Data Day event happening in Manila, 250 kilometers away, and led by OSM-PH community enthusiasts we managed to map over 250 schools, typically equivalent to a month’s worth of edits.

Thank you, too, to Mr. RIc Saturay of the Philippine Science High School Cordillera Campus, for linking us up.
