Who is Schadow1?

Schadow1 Expeditions

You might have heard or come across Schadow1 ( shadow 1 expeditions ) one way or another in cyberspace since 1997 as this has been the expeditioner's internet handle ever since. Someone who has been a netizen since mIRC, Iconn Chat, PinoyPC, PinoyExchange of the 90's and customized motherboard firmware development, skin development of the early smartphones and desktop PC chassis airflow design of the early 2000's.

He is a gadget enthusiast and one may call a techy during his teenage years and 20's. Although started early having climbed his first mountain at the age of 8, driving a vehicle at the age of 12; the blogger's adventurous side has been forgotten. Not until one day sometime in the year 2004 when he was enticed with aerial and satellite imagery... where his early age of adventure has met its technological counterpart, mapping the Philippines.

Since 2005, the writer has been mapping the Philippines and contributing the data to three mapping consortia namely RoadGuide Philippines, Google Mapmaker, and OpenStreetMap Philippines. Which the data is currently used for navigation guidance and humanitarian mission planning.

Due to the scarcity of the satellite imagery coverage of the Philippines for tracing, he has then started to leave his desk and went on traveling the Philippines and climbing its mountains to map trails, roads and waypoints not yet covered. This resulted in the rebirth of his adventurous childhood.

Schadow1 Expeditions website was born on November 26, 2012, as a diary of experiences while traveling the Philippines and performing its mapping advocacy.

The writer is a graduate of Multimedia Arts at De La Salle - College of Saint Benilde and Electronics and Communications Engineering at De La Salle University. He has started Schadow1 Expeditions as a journal for covering the Philippines as a backpacker, mountaineer, a driver, and a motorcycle tourist; bringing experiences, memories, and photographs of the places he has been to while mapping it to ensure that a Filipino would not be a stranger to his motherland. He also provided free consultancy to the country's National Disaster Risk Reduction Management Council (NDRRMC) Information Management - Technical Working Group. This is all while he earns a humble living as a geospatial scientist in the energy industry.

His passion for technology, arts, and geography enables a mixture that resembles a modern-day adventurer while transforming arts and environmentalism into functional and humanitarian solutions.
