Aerial LiDAR Mapping of the entire City of Baguio


Project Brief

As the country’s leader in LiDAR surveying, AB Surveying and Development completes the first ever citywide LiDAR mapping to arrive with survey-grade maps, including an aerial photo, digital surface model and digital terrain model (DSM-DTM), topographic and waterways map and as-built maps of structures, houses, roads, drainage system and surface utilities, suitable for engineering applications.


Baguio City, 5,750 hectares in area, is a highland retreat in the Grand Cordillera of Northern Luzon and is characterized as a highly urbanized mountainous area. If it were to be surveyed using conventional methods, it could have taken several years to gather that voluminous data on land. Through the advancement of technology, this timeframe has been reduced to a record time that seemed unimaginable a few years ago. Baguio City’s aerial LiDAR survey was conducted by mounting a LiDAR equipment from a helicopter and gathering data by grazing and sweeping Baguio City line after line during a flight scan that lasted for a total of only eight (8) hours.


The Government of Baguio City, in their initiative to sustain projects for city-wide infrastructure planning, road network management, flood mapping, tax mapping and disaster risk management, shares this feat with ABSD in a press conference held last November 27, 2018 at the City Multipurpose Hall.
