FILGEO has been providing not only land survey services to First Balfour Inc. but also aerial survey services. Aerial survey was done for the Batangas project in Sto. Tomas, Batangas. The total area to be surveyed was about 910 hectares. Ground Control Point Acquisition was also performed to aid in the processing of the aerial data. Results from the survey were used to produce an Orthophoto map, Digital Surface Model (DSM) and Digital Terrain Model (DTM) of the area of interest.
