Our journey through Marinduque had been a thrilling cycling adventure, and the last leg was both the shortest and the most demanding. Our destination: the Luzon Datum of 1911, the geodetic center of the Philippines, perched atop Mt. Mataas in Mogpog, rising approximately 200 meters above sea level. It was the perfect way to conclude our cycling odyssey on this captivating island.
If you’ve ever wondered how the shapes of the islands, the elevation of peaks, and the depths of seas are measured and translated into easily readable maps that common people can understand, it’s all about the science of geodesy and datums. Even before Google Maps ever existed, surveyors and scientists used datums or geodetic reference points to collectively gather information on the lay of the land and sea in longitude and latitudes. That is why I had much appreciation to finally visit the Luzon Datum of 1911 site in Marinduque. A pivotal reference point used to triangulate networks of different datums in the country. It is, literally the center of the Philippines in a geodetic sense.
