Can you try this one ? https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb-data/blob/master/Input/DEM/egm96.grd

Thanks for the quick reply. In fact I used dem respect to the geoid. So, I added the EGM96 Geoid Model as a geoid file (The Trimble Format GGF file: Ww15mgh.ggf). Unfortunately, the result does not change. Where am I wrong? Thank you Le jeudi 3 mai 2018 13:01:45 UTC+2, Julien Michel a écrit : Hi, Is your DEM with respect to ellipsoid or geoid ? All computation in OTB are done with respect to the ellispoid, so if your DEM is with respect to geoid, you need to add a geoid file.

First, I used the application otbgui_ReadImageInfo and I got: Image general informations: Number of bands : 1 Start index : [0,0] Size : [21948,17320] Origin : [0.5,0.5] Spacing : [1,1] Estimated ground spacing (in meters): [0.698578,0.701359] Image acquisition informations: Sensor : Image identification number: Country : Italy Town : Cretaio Image footprint coordinates: Upper left corner (latitude, longitude) = [40.7882,13.8442] Upper right corner (latitude, longitude) = [40.7899,14.0263] Lower left corner (latitude, longitude) = [40.679,13.8461] Lower right corner (latitude, longitude) = [40.6807,14.0278] Image default RGB composition: [R, G, B] = [0,1,2] Ground control points information: Number of GCPs = 0 GCPs projection = instead the dem I'm using is: Image general informations: Number of bands : 1 Start index : [0,0] Size : [20001,12001] Origin : [13.8509,40.7616] Spacing : [5.80956e-006,-5.79988e-006] Estimated ground spacing (in meters): [0.489746,0.644903] Image acquisition informations: Sensor : Image identification number: Image projection : GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433], AUTHORITY["EPSG","4326"]] Image default RGB composition: [R, G, B] = [0,1,2] Ground control points information: Number of GCPs = 0 GCPs projection = at the end of the orthorectification with otbgui_OrthoRectification I get the image correctly orthorectified, but moved about 40 m to the North-East. What is the reason for this shift?
