Topographic survey using an Unmanned Aerial Vehicle was done for Semirara Mining and Power Corporation in Caluya, Antique. A total of five (5) stockpile areas were surveyed. Results were used to determine the volume of the selected stockpiles. For the topographic survey performed, GPS and Total Station were used and control points from the site served as reference. The results were used as basis for adjustments made in the processing for volume computation. Orthophoto Maps, Elevation Models and plans and profiles were generated from the survey.
