ASPRS National offers certification in GIS, Remote Sensing, Photogrammetry, LiDAR, and UAS,
at two levels for each discipline!
ASPRS was the first professional organization to offer certification in these disciplines, and its certification program is the most robust. The exams are difficult, and you need to know your stuff.
