Dear Community,
I would appreciate if anyone can clarify my doubt.
what is the impact of DEM density on Orthophoto accuracy.
Will DEM density vary terrain to terrain to acheive same level of ortho ac=
curacy?
To acheive cetain ortho accuracy what is the appropriate DEM density for an=
y type of terrain.
Of course,other factors like scanning ,DEM ,EO accuracies also will have im=
pact on Ortho accuracy.
But I like to know the Impact of DEM density alone on Ortho accuracy.
Thanks in advance,
sudhagar
