In this case study, we first set possible sensor locations by creating a 3D grid over the entire site. The resolution for the two horizontal directions (Northing and Easting) is 1 m while the resolution for the vertical direction is 0.5 m. The dimensions of the METEC site are approximately 125 meters in Easting and 75 meters in Northing. Considering practical feasibility, the vertical range was designated as spanning from 1 to 10 meters. Subsequently, we excluded all points within the grid that were occluded by any of the five equipment groups present on the site. This exclusion process resulted in a total of 21,774 viable sensor locations, forming the search space for the subsequent optimization analysis. Figure shows the possible sensor locations as well as the potential emission sources on the METEC site.
