Hello all,
I'm a graduating student and for my dissertation I'm trying to orthorectify a QuickBird satellite image, which I think is an ortho-ready product, so I add the "?&skipcarto=true" at the end of the input image filename.
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?
Thank you in advance
Felicia
