Testing the PDEM to Control the Precision of an IFSAR DEM
Authors: , , ,
Abstract: The Perpendicular Distance Estimation Method (PDEM), a method to estimate the precision of a Digital
Elevation Model (DEM), in “Effectiveness of Geometric Quality Control Using a Distance Evaluation Method”
was tested assuming independent normal random for the vertical and horizontal error, considering isotropic this
horizontal error. Here the PDEM is tested in the case of a DEM obtained by IFSAR technology, also, assuming
independent normal random errors, but this time in three independent directions. Because vertical direction is
correlated with one horizontal direction, -the range axis direction-, a rotation has to be done and so, three
independent directions are obtained.
