the images in the correct positional accuracy for orthorectifying and mapping. He also created orthophotos and used Inpho's OrthoVista module to mosaic the orthorectified images into a seamless orthomosaic of the entire AOI at a 2D accuracy of 1.2 in. Lafica then repeated the same process with the 80 oblique images. UASMaster automatically deciphered the unique characteristics of off-nadir imaging and triangulated them in 45 minutes. "One of the reasons we use UASMaster is because of its photogrammetric power," said Lafica. "To accurately tie the oblique images together, the software needed to use different routines and algorithms to figure out puzzles like the camera lens distortion values. And it did. That was a level of smart I didn't expect." About one week after the field survey, Lafica delivered the 3D topographic map, the orthomosaic and a vector-based DTM to the customer, definitively answering any questions around the uncertainty of mapping oblique UAS images in 3D.
